How to Reset Your Kenmore Refrigerator Control Panel (The Definitive Guide)

Seeing a flickering display or a sudden “Er” code on your fridge is a panic moment for any homeowner. Before you rush to call a repair technician, you need to know How to Reset Your Kenmore Refrigerator Control Panel.

Often, power surges or software glitches cause the main control board to freeze, halting ice production and cooling. A simple “hard reset” or specific button sequence—like holding “Home” and “Ultra Ice”—can restore functionality in seconds. This guide covers the precise reset protocols for Kenmore Elite and standard models, helping you save food and service fees immediately.

Why Your Refrigerator’s Brain Needs a Reboot

Just like a computer or a smartphone, your refrigerator’s main control board (PCB) can get its signals crossed. An unresponsive panel is the most common symptom of a confused processor. Several factors can cause this.

The Impact of Unstable Power

The sensitive electronics in your refrigerator are designed for a steady, consistent flow of electricity. When that flow is disrupted, the control board can freeze up.

• Power Surges: A brief, intense spike in voltage, often from a nearby lightning strike or the power grid being restored after an outage, can overwhelm the circuitry.
• Sags and Brownouts: These are drops in voltage that can starve the control board of the power it needs, causing it to lock up or behave erratically.

Internal Software Glitches and Stuck Buttons

Sometimes, the problem is purely digital.

• Software Glitches: The internal software that runs your refrigerator can encounter a bug, causing it to enter a frozen state. This can happen for no apparent reason, just like any other computer.
• Stuck Buttons: If a button on the control panel is physically stuck or a spill has created a short circuit, the control board may be receiving a constant, single command. This can make the entire panel unresponsive as it tries to process the endless input.

Is It Broken, or Just in a Special Mode?

Before assuming a failure, make sure the panel isn’t simply in a special mode.

• Control Lock (Child Lock): This feature is designed to prevent accidental changes. If active, a small lock icon is usually illuminated, and the panel will not respond. Disabling it, typically by pressing and holding the “Lock” button for three seconds, will restore function.
• Demo Mode (Showroom Mode): If the lights are on but the refrigerator isn’t cooling, it may be in Demo Mode. This is a setting used in retail stores. The display might show “OF F” or “O FF”. We will cover the specific button combinations to exit this mode in Section 2.

The Hard Reset: Your First and Most Powerful Tool

There are two types of resets: a “soft reset,” which uses a button combination, and a “hard reset,” which involves a full power cycle. While we will cover specific button combinations later, the hard reset is the universal solution that works on nearly all models and resolves the vast majority of electronic glitches.

The goal of a hard reset is to completely drain all residual power from the main control board and its components, forcing the internal memory to clear. This erases any temporary glitches, just like rebooting your computer.

Step-by-Step Guide to Performing a Hard Reset:

1. Access the Plug.Carefully pull the refrigerator straight out from the wall. You only need enough space to comfortably reach the outlet behind it.
2. Unplug the Refrigerator.Firmly grip the plug and pull it directly from the wall socket. You’ll feel the solid disconnect.
3. Wait for at Least 5 Minutes.This is the most important step. Do not skip it. The main control board has capacitors, which are like tiny batteries that store a small electrical charge. Simply unplugging and immediately replugging the unit is not enough time for these capacitors to fully discharge. You must wait for a minimum of five minutes (ten is even better) to ensure the board’s memory is completely wiped clean.
4. Plug It Back In.After waiting, plug the refrigerator back in. You should hear the compressor kick on within a few moments, and the control panel should light up, often with a flash or a beep.
5. Observe and Calibrate.The panel is now reset. The temperature readings may be flashing or showing default settings. Give the refrigerator a few minutes to recalibrate and display the current internal temperatures. At this point, the panel should be fully responsive.

 

Pro-Diagnostic Tip: If you perform a hard reset and the control panel comes back to life, but then freezes again a day or two later, it’s a strong sign that your home may be experiencing frequent, minor power fluctuations. This is a good time to consider a dedicated surge protector, which we cover in our maintenance section.

 

Hard Reset Checklist	Status
1. Refrigerator unplugged from the wall	☐
2. Waited a full 5-10 minutes	☐
3. Refrigerator plugged back in	☐
4. Control panel lights up	☐
5. Compressor sound confirmed	☐

 

Seasonal Intelligence: Thunderstorm season is prime time for control panel glitches. Power grids are most unstable during severe weather. If you experience a flickering of lights or a brief outage during a storm, don’t be surprised if your refrigerator needs a hard reset afterward. Unplugging it ahead of a major storm is the best preventative measure.

Preventive Actions Checklist

• Check for Stuck Buttons: Gently wipe your control panel with a damp cloth to clean any sticky residue from around the buttons that could cause them to stick.
• Know Your Breaker: Identify which circuit breaker in your home’s electrical panel controls the refrigerator. In a pinch, you can use this to perform a hard reset if you cannot access the plug.
• Listen for Clicks: If a reset fails and you hear a faint, repetitive “clicking” sound coming from the back of the refrigerator, it could be a sign of a failing relay on the main control board, which will require professional service.

If a full power cycle didn’t resolve your control panel issue, don’t worry. The next step is to investigate model-specific “soft resets” and to understand what the panel might be trying to tell you with an error code.

This is where a crucial piece of information comes into play: Kenmore doesn’t actually manufacture its own refrigerators. They are typically made by other major brands like LG, Whirlpool, or Frigidaire. Finding the right reset procedure depends entirely on identifying the original manufacturer.

 

The Kenmore Secret: Who Made Your Refrigerator?

The key to unlocking the correct reset sequence is hidden in your refrigerator’s model number. Open the refrigerator door and look for the model number sticker, usually located on the interior side wall or along the door frame. The first three digits of the model number, followed by a dot, will reveal the original equipment manufacturer (OEM).

• XXXXX:Your refrigerator was made by LG.
• XXXXX or 596.XXXXX:Your refrigerator was made by Whirlpool.
• XXXXX:Your refrigerator was made by Frigidaire.

Once you know the manufacturer, you can use the correct button combinations to access diagnostic and reset functions.

Manufacturer-Specific Reset and Diagnostic Sequences

After a hard reset fails, these button combinations are your next logical step. A successful reset is often confirmed by a beep or chime, or by the control panel lights flashing before returning to normal.

For LG-Made Kenmore Models (795. series)

LG models often have the most accessible diagnostic modes.

• General Reset:Press and hold the ULTRA ICE and REFRIGERATOR TEMPERATURE buttons at the same time for five seconds or more.
• Exit Demo Mode:If the lights are on but there’s no cooling, open both refrigerator doors and press and hold the REFRIGERATOR and ICE PLUS (or Ultra Ice) buttons simultaneously for about five seconds. You should hear a beep to confirm the mode is deactivated.
• Forced Defrost:To clear ice-related errors, you can force a defrost cycle by pressing and holding the FREEZER and REFRIGERATOR buttons at the same time for five seconds.

 

For Whirlpool-Made Kenmore Models (106. or 596. series)

Whirlpool models rely more heavily on the hard reset, but have a specific sequence for the common “Demo Mode” issue.

• Exit Demo Mode:If “Cooling Off” is displayed on the panel, press and hold the FRIDGE and FREEZER temperature buttons simultaneously for three seconds.
• Temperature Reset:To reset just the temperature settings, press and hold the “Fridge Temp” and “Freezer Temp” buttons at the same time until you hear a beep.

 

For Frigidaire-Made Kenmore Models (253. series)

Frigidaire models have several known combinations for exiting showroom mode.

• Exit Showroom/Demo Mode:Try one of the following:
  1. Press and hold the Lockand Light buttons at the same time for about 3 seconds.
  2. Simultaneously press and hold the minus (-)button and the Water Filter button for about 10 seconds.
• Enter Diagnostic Mode:To view error codes, press and hold the freezer temperature Up (▲) and Down (▼) arrow buttons at the same time for 5 to 10 seconds.

 

Decoding Common Kenmore Error Codes

If your control panel is displaying an error code, it’s providing a valuable clue to the root problem. A reset may clear the code temporarily, but if it returns, it means a specific hardware component needs attention.

 

Error Code	Meaning and Potential Cause
OF F or O FF	Cooling Off / Demo Mode. This is not a true error. The cooling system has been disabled. Use the manufacturer-specific button combinations above to exit this mode.
Er CO	Communication Error. There is a connection issue between the main control board and the user display board. This is often caused by a loose or damaged wire harness.
Er FF or FF	Freezer Evaporator Fan Failure. The fan that circulates cold air in the freezer has failed. This could be due to a bad fan motor, loose wiring, or a physical obstruction from ice buildup.
Er IF or r IF	Ice Compartment Fan Failure. The fan in the icemaker compartment has failed. This is often caused by moisture shorting out the fan, which can also damage the main control board.
Er dH, F dH, r dH	Defrost System Failure. This is a critical error. It means the automatic defrost cycle failed to melt the frost off the evaporator coils. The cause is a faulty defrost heater, defrost thermostat (bi-metal), or thermal fuse.
Er FS / Er rS	Freezer Sensor (FS) or Refrigerator Sensor (rS) Error. The temperature sensor in the respective compartment has failed and is sending inaccurate readings to the main board.
Er CF	Condenser Fan Motor Error. The fan that cools the condenser coils and compressor at the back of the unit has failed.

 

What Common Advice Gets Wrong: Do not just start pressing random button combinations. Without knowing your refrigerator’s original manufacturer, you could accidentally put the unit into a diagnostic or demo mode that is difficult to exit. Always identify the OEM via the model number first. The hard reset (power cycle) is the only universally safe procedure.

 

Preventive Actions Checklist

• Photograph Your Model Number:Take a clear picture of the model number sticker inside your refrigerator door and save it to your phone. This will save you a major headache if you ever need to look up a part or procedure.
• Keep the Manual:Store your user manual in a safe, accessible place. It contains the specific reset and diagnostic information for your exact model.
• Address Error Codes Promptly:Don’t ignore a recurring error code. A defrost system failure (Er dH), for example, will lead to massive ice buildup and eventually cause the entire refrigerator to stop cooling.

You’ve performed the hard reset, and you’ve tried the manufacturer-specific button combinations, but the control panel remains unresponsive or an error code keeps returning. This is the point where the problem transitions from a simple software glitch to a hardware failure.

But that doesn’t automatically mean you need to call a repair service. With a simple tool—a multimeter—and a methodical approach, you can often diagnose the faulty component yourself. This section will guide you through testing the most likely hardware culprits.

Your First Hardware Check: The Door Switch

Before diving into complex circuit boards, there’s one more simple component to check: the door switch. This small switch tells the main control board whether the door is open or closed. If it fails, it can send an incorrect signal that can make the control panel unresponsive or behave erratically.

How to Test a Door Switch:

1. SAFETY FIRST: Disconnect All Power.Unplug the refrigerator from the wall.
2. Locate and Remove the Switch.The door switch is a small plunger-style button located along the door frame. Carefully pry it out with a putty knife or a flathead screwdriver.
3. Disconnect and Test.Disconnect the wires from the switch. Set your multimeter to the continuity setting (it will beep when the probes touch). Touch one probe to each of the switch’s terminals.
   • When the plunger is not pressed(door open), the multimeter should have continuity (it will beep).
   • When the plunger is pressed(door closed), the continuity should break (the beeping will stop).
   • If the switch fails either of these tests, it is faulty and needs to be replaced. This is an easy and inexpensive fix.

Main Board vs. Display Board: Identifying the True Culprit

If the door switch is working, the problem lies with one of two circuit boards: the user control and display board (the panel you touch) or the main control board (PCB) (the refrigerator’s brain). Distinguishing between them is key.

• Symptoms of a Failed User Control/Display Board: The refrigerator is still cooling and running normally, but some or all of the buttons on the control panel don’t work, or the display is blank or garbled. This points to the board you interact with.
• Symptoms of a Failed Main Control Board (PCB): The problem is more widespread. The entire control panel is dead, and the refrigerator is not cooling, the compressor won’t run, or you hear a faint, rhythmic clicking sound from the back of the unit. This points to the main brain.

Diagnosing a Failed Main Control Board (PCB)

If signs point to the main board, a visual inspection can often confirm the diagnosis.

1. Access the Board.With the refrigerator unplugged, locate the main control board. It’s usually on the back of the unit behind a metal or plastic access panel. Remove the screws to expose the board.
2. Perform a Visual Inspection.Carefully examine the board for obvious signs of electrical failure.
   • Look for burn marks or blackened spotson the board.
   • Check the capacitors(small, can-shaped components). If the tops are bulging or leaking fluid instead of being perfectly flat, the board has failed.
   • Look for any signs of corrosion or loose connections.

If you see any of these signs, the main control board needs to be replaced.

Safety Guardrails & What Common Advice Gets Wrong: You may see guides on testing a live control board for voltage with a multimeter. DO NOT ATTEMPT THIS unless you are an experienced technician.

 

Working on a live circuit board carries a high risk of electric shock and can cause further damage to the appliance. A visual inspection is the safest and often most conclusive diagnostic step for a DIYer. If a visual inspection is inconclusive, it’s time to call a professional.

Special Case: Diagnosing a Defrost System Error (Er dH)

If your panel is showing a defrost error code (Er dH, F dH, Er FF, etc.), the problem is in a specific system. After performing a manual defrost to melt the ice, you can test the components located behind the freezer’s back panel.

• Defrost Heater: Disconnect and test with a multimeter set to Ohms (Ω). A good heater will show a resistance reading, typically between 10 and 150 ohms.
• Defrost Thermostat (Bi-metal): This must be tested when cold. It should have continuity when cold (in ice water) and no continuity at room temperature.
• Thermal Fuse: This should always have continuity. If it doesn’t, it has blown and must be replaced.

If all these components test good, but the defrost error returns, the main control board is the culprit, as it is failing to send power to the defrost system.

 

Maintenance Checklist

• Invest in a Surge Protector: The single best thing you can do to protect your refrigerator’s electronics is to plug it into a dedicated appliance surge protector with a high joule rating (1000-4000 joules).
• Keep it Clean: Gently wipe your control panel regularly with a damp, soft cloth to prevent sticky buildup that can cause buttons to fail.
• Ensure Good Airflow: Do not block the vents inside the refrigerator or freezer. Proper airflow is critical for the defrost system to work correctly and prevent ice buildup that can lead to fan errors (Er FF).

You’ve successfully navigated the world of resets, error codes, and hardware diagnostics. Whether you solved your issue with a simple power cycle or by replacing a faulty component, the final step is to ensure the problem doesn’t happen again. Proactive care is the key to a long and reliable life for your refrigerator’s sensitive electronics. This section covers the essential preventative measures every homeowner should take.

Protecting Your Refrigerator’s Electronics from Electrical Risks

The main control board is the most expensive component to replace, and it’s highly vulnerable to damage from unstable electricity. Protecting it is a wise investment.

• Use a Dedicated Appliance Surge Protector: This is the single most important thing you can do. Do not use a standard power strip from an office supply store, as it cannot handle the high power draw of a refrigerator’s compressor and can be a fire hazard. An appliance surge protector is specifically designed for this task.
  • Joule Rating: Look for a rating of at least 1,000 to 2,000 joules. For maximum protection, especially in areas with frequent storms, a rating between 2,000 and 4,000 joules is ideal.
  • Clamping Voltage: This is the voltage at which the protector kicks in. Lower is better. Aim for a clamping voltage of 400 volts or less.
  • Indicator Light: Choose a model with an indicator light that confirms it is still providing protection. Surge protectors wear out after absorbing a major surge.
• Consider Whole-House Protection: For the ultimate defense, a whole-house surge protector can be installed at your main electrical panel by a qualified electrician. This protects every circuit in your home from external power surges.
• Practice Power-Outage Safety: During a severe storm, unplugging your refrigerator is the only foolproof protection. After an outage, wait 5-10 minutes before plugging it back in. This prevents the compressor from being damaged by the initial surge of returning power.

Safe Cleaning Procedures for the Control Panel

Moisture is the enemy of any electronic panel. Proper cleaning prevents short circuits and keeps buttons from getting stuck.

• Never Spray Directly: Never spray any cleaning liquid directly onto the control panel.
• Use a Mild Solution: The safest and most effective cleaner is a simple solution of warm water with a few drops of mild dish soap.
• Apply with a Soft Cloth: Lightly dampen a microfiber cloth with the solution. The cloth should be moist, not dripping wet.
• Wipe Gently: Clean the panel with gentle motions. For grime around the edges of buttons, use a lightly dampened cotton swab.
• Dry Thoroughly: After cleaning, immediately wipe the panel with a clean, dry, soft cloth to remove all moisture.
• Avoid Harsh Chemicals: Do not use cleaners containing ammonia, bleach, alcohol, or other abrasive chemicals, as they can damage the panel’s surface and electronics.

 

Maintenance Best Practices	Frequency
1. Check surge protector indicator light	Monthly
2. Wipe down control panel with a damp cloth	As needed
3. Inspect door gaskets for a proper seal	Annually
4. Clean condenser coils (if accessible)	Annually

FAQ

Is it expensive to replace a main control board?

A new main control board can cost anywhere from $100 to $300+, depending on the model. A professional installation can add another $150-$200. Because of this cost, it’s crucial to rule out all other possibilities before replacing the main board.

My control panel works, but the display is dim or unreadable. What’s the problem?

This almost always points to a failure of the user control and display board. The main board is functioning and running the refrigerator, but the display itself has failed.

I hear a clicking sound from the back of my fridge. What is that?

A repetitive clicking sound, happening every few minutes, is a classic symptom of a failed relay on the main control board. The board is trying to send power to the compressor to start it, but the relay is failing, causing the clicking sound and a no-cool situation. The board will need to be replaced.

Can I replace the main control board myself?

If you are comfortable with basic repairs, yes. It is typically a plug-and-play process. Take a picture of the wire connections before you begin, carefully swap the boards, and reconnect all the harnesses. However, if you are at all unsure, this is a good job to leave to a professional.

My panel is fine, but the ice maker and water dispenser don’t work. What should I check?

First, check for a “Control Lock” feature, as this often disables the dispenser. If that’s not the issue, check that the water supply line is not frozen. If both are fine, the problem could be the dispenser’s own control board, the water inlet valve, or the door switch, which on many models must be engaged for the dispenser to operate.

I tried the button combination for my model, and nothing happened. What’s next?

If both a hard reset and the correct soft reset sequence fail, it strongly suggests a hardware failure. The issue could be a faulty user control board (the panel you touch), a damaged wire harness, or a failed main control board. Section 3 will cover how to diagnose these hardware issues.

My refrigerator is displaying “0 F”. Is this an error code?

No. A display of “0 F” is simply indicating that the freezer temperature is set to 0 degrees Fahrenheit. This is a normal display, not an error. An error code is typically “OF F” (with the letter O) or another combination of letters and numbers.

Can I clear an error code just by resetting the panel?

Yes, a hard reset will almost always clear the error code from the display. Underlying hardware problem has not been fixed (e.g., a bad defrost heater), the control board will detect the failure again on the next cycle, and the error code will reappear.

Why do I have to wait 5 minutes? I unplugged it and plugged it back in, and nothing happened.

The waiting period is non-negotiable. The electronic components on the control board hold a residual electrical charge. If you plug it back in too quickly, that charge is never fully cleared, and the board’s memory doesn’t get wiped. The glitch you’re trying to fix will still be there. The 5-minute wait ensures a complete reboot.

Will resetting my refrigerator change my temperature settings?

Most modern refrigerators will remember your last temperature settings after a hard reset. However, some models may revert to a factory default setting (e.g., 37°F for the fridge and 0°F for the freezer). Always double-check the settings on the control panel after it reboots.

Can I just flip the circuit breaker instead of unplugging it?

Yes. Cutting the power at the circuit breaker achieves the same result as unplugging the unit. This is a useful alternative if your refrigerator is in a tight space and you cannot easily access the outlet. Just be sure to leave the breaker off for the full 5-10 minute waiting period.
