Is your refrigerator not cooling properly? You might need to reset the compressor. This simple fix often solves cooling issues without requiring expensive repairs. To reset a refrigerator compressor, unplug the refrigerator from the power outlet for about 10-15 minutes, then plug it back in.
This reset gives the compressor—the heart of your cooling system—time to rest and restart. It’s similar to restarting your computer when it freezes. Sometimes the compressor can get overworked or stuck in a cycle that prevents proper cooling. The short break allows the system to clear any temporary issues.
Before attempting a reset, make sure to remove any food that might spoil quickly. After plugging the refrigerator back in, you may hear some normal noises as the compressor starts working again. Give your fridge a few hours to return to its proper cooling temperature before deciding if the reset worked or if you need professional help.
How To Reset Your Refrigerator Compressor
If your refrigerator isn’t cooling properly or seems to be cycling on and off erratically, the compressor may need a reset. The compressor is essentially the heart of your fridge’s cooling system, and a quick reset can sometimes solve common problems without needing a service call. Here’s how to do it safely and easily.
Step-by-Step Guide To Reset Your Refrigerator Compressor
Step 1: Unplug the Refrigerator
Start by pulling the refrigerator’s plug from the wall outlet. This completely disconnects it from power and helps clear out any lingering electrical charge in the system.
Step 2: Turn Off the Temperature Controls
Inside the fridge, turn both the refrigerator and freezer temperature dials to “Off” or the lowest possible setting. This ensures the compressor won’t immediately turn back on when you plug it back in.
Step 3: Wait 5 to 10 Minutes
Give the refrigerator a few minutes to fully reset. Waiting allows residual power to drain from internal components like the compressor and control board.
Step 4: Plug the Refrigerator Back In
After the wait, plug your fridge back into the outlet. You may hear a slight humming noise after a minute or two—that’s the compressor starting up again.
Step 5: Turn the Temperature Controls Back On
Set your fridge and freezer dials back to your desired temperature. Typically, the refrigerator should be around 37°F (3°C) and the freezer around 0°F (-18°C).
Step 6: Allow the Refrigerator to Stabilize
It may take a few hours for the temperature to return to normal. Keep the doors closed as much as possible during this period.

Understanding Your Refrigerator’s Compressor
The compressor is the heart of your refrigerator’s cooling system. It pumps refrigerant through the system and creates the pressure needed to remove heat from inside your fridge.
Components of the Compressor System
The compressor works together with several key parts to keep your food cold. The main components include:
- Compressor motor: Provides power to compress the refrigerant gas
- Condenser coils: Usually located at the back or bottom of the fridge where heat is released
- Evaporator coils: Located inside the refrigerator where cold air is produced
- Expansion valve: Controls refrigerant flow into the evaporator
- Start relay: Helps the compressor motor start up
- Overload protector: Prevents the compressor from overheating
The compressor system also includes a thermostat that monitors the temperature inside your refrigerator. When the temperature rises above the set point, the thermostat signals the compressor to start working.
How the Compressor Affects Cooling
When your compressor is working properly, it pressurizes refrigerant gas. This process is essential for the cooling cycle to function properly.
First, the compressor squeezes refrigerant gas, heating it up. The hot gas then flows to the condenser coils where it releases heat and changes to liquid form.
The liquid refrigerant moves to the evaporator coils inside the fridge where it expands and absorbs heat. This cooling effect is what keeps your food fresh.
If your refrigerator is not cooling properly, the compressor might be to blame. Common signs include unusual noises from the back of the fridge, warm food, or the motor running constantly without cooling.
The evaporator fan helps distribute cold air throughout the refrigerator. Without proper airflow from this fan, even a working compressor can’t keep your food cold effectively.
Signs of a Compressor in Need of Reset
Your refrigerator compressor may need a reset when it shows certain warning signs. Recognizing these problems early can prevent bigger issues and costly repairs.
Inconsistent Temperature Levels
When your refrigerator fails to maintain proper cooling, the compressor might need a reset. You may notice foods spoiling faster than normal or ice cream becoming soft in the freezer. The temperature might fluctuate throughout the day, with items cold one moment and warm the next.
Check the temperature settings first to rule out a simple adjustment problem. Many refrigerators should be set between 37-40°F for the fridge section and 0-5°F for the freezer. If the settings are correct but cooling remains inconsistent, this points to a compressor issue.
You might also notice the fan running constantly while the fridge struggles to reach the set temperature. This overworking puts strain on the system and wastes electricity.
Unusual Noises from the Compressor
A healthy compressor makes a low humming sound when operating. Strange noises like clicking, knocking, or buzzing often signal a compressor problem that might benefit from a reset.
Listen for these sounds:
- Clicking: Repeated clicking when the compressor tries to start
- Buzzing: Electrical problems within the compressor
- Knocking or banging: Mechanical issues with compressor components
These noises tend to be loudest near the back or bottom of the refrigerator where the compressor is located. Sometimes the noise comes and goes, becoming more noticeable when the cooling cycle begins.
If strange sounds persist after a reset, you might have a more serious compressor issue requiring professional attention.
Compressor Overheating
An overheating compressor is a serious warning sign. Touch the exterior back wall of your refrigerator carefully – it should feel warm but not hot. If it’s uncomfortably hot to touch, the compressor might be overheating.
You might notice these additional signs:
- Refrigerator exterior feels very hot near the compressor area
- Circuit breaker trips repeatedly
- Burning smell coming from the back of the unit
- Compressor shuts off unexpectedly
Dust buildup around the compressor coils can cause overheating. Before resetting, check if the coils need cleaning. Make sure there’s proper ventilation space (about 2-3 inches) between the refrigerator and the wall.
Overheating issues that continue after resetting could indicate a malfunctioning compressor that needs replacement.
Safety Precautions Before Resetting
Before attempting to reset your refrigerator compressor, take proper safety measures to protect yourself and your appliance. Electrical safety should be your top priority when working with any kitchen appliance.
Disconnecting Power
Always unplug your refrigerator before attempting any reset procedure. This step is crucial for your safety and prevents electrical shock. Locate the power cord at the back of your refrigerator and pull it straight out from the wall outlet. Don’t yank the cord or pull it at an angle.
If your refrigerator is built-in or difficult to move, turn off the dedicated circuit breaker instead. Make sure everyone in the household knows you’re working on the appliance.
Wait at least 10 minutes after disconnecting power before proceeding with any reset. This delay allows the electrical components to fully discharge and ensures the compressor isn’t in an overload state.
Checking the Circuit Breaker
Before assuming your compressor needs resetting, check your home’s circuit breaker panel. Look for a tripped breaker that controls your kitchen or specifically your refrigerator. A tripped breaker may appear slightly out of alignment with others or show a red indicator.
If you find a tripped breaker, switch it fully to the “off” position first, then firmly push it back to the “on” position. This proper reset technique helps prevent damage to the circuit breaker.
Sometimes power surges can trip breakers without being obvious. If your refrigerator isn’t running properly, this simple check might solve the problem without needing to reset the compressor itself.
The Reset Process
Resetting a refrigerator compressor is a straightforward task that can solve many cooling issues. The process involves disconnecting power and following specific steps to allow the compressor to restart properly.
Locating the Reset Button
Most refrigerators don’t actually have a dedicated compressor reset button that’s accessible to users. Instead, the compressor has a self-resetting thermal switch that works automatically. This switch turns off the compressor if it overheats and turns it back on when the temperature drops to a safe level.
For some refrigerator models, particularly older ones, there might be an overload protector or relay near the compressor. These components are typically located at the back of the refrigerator near the bottom where the compressor sits.
If your refrigerator has continued problems, check the owner’s manual for model-specific information about reset mechanisms or switches.
Steps to Safely Reset the Compressor
The most effective way to reset a refrigerator compressor is by doing a power cycle:
- Turn off power – Unplug the refrigerator from the wall outlet or turn off the circuit breaker.
- Wait patiently – Leave the refrigerator unplugged for about 10-15 minutes. This allows the compressor system to equalize pressure and the control board to reset.
- Restore power – Plug the refrigerator back in or turn the circuit breaker on.
- Adjust settings – Set the temperature controls to the recommended settings.
You might hear whooshing or knocking noises when the refrigerator restarts – this is normal. The cooling process should begin within a few hours.
If the refrigerator still doesn’t cool properly after resetting, check for other issues like a stuck defrost timer or blocked vents. These problems might require additional troubleshooting.
Post-Reset Checks
After resetting your refrigerator compressor, it’s essential to verify that everything is working properly. These checks help ensure your appliance is cooling correctly and prevent future issues.
Confirming the Compressor Restart
Listen for a gentle humming sound from the back or bottom of your refrigerator. This noise indicates the compressor is running again. Place your hand near the compressor area to feel for slight vibrations or warmth, which are normal signs of operation.
Check if the internal light turns on when you open the door. While this doesn’t directly confirm the compressor is working, it shows the refrigerator has power.
The fan should also be running if your model has one. Listen for its sound or feel for airflow inside the refrigerator. No airflow might mean the fan isn’t working properly, even if the compressor restarted.
Monitoring Temperature Consistency
Set your refrigerator thermostat to the manufacturer’s recommended temperature – usually between 37-40°F (3-4°C) for the refrigerator section and 0°F (-18°C) for the freezer. Use a separate thermometer to verify these readings, as built-in displays can sometimes be inaccurate.
Monitor temperatures over 24 hours. Temperatures should steadily decrease and then maintain consistency. Record readings at different times to spot any unusual patterns.
Check various spots inside the refrigerator for cold air distribution. Some areas may be colder than others, but extreme differences might indicate air circulation problems.
If temperature settings need frequent adjustments or the unit can’t maintain consistent cooling, your compressor might need professional attention despite the reset.
When to Call a Professional
Sometimes refrigerator compressor problems go beyond simple reset solutions. Knowing when to seek expert help can save you time, money, and prevent further damage to your appliance.
Troubleshooting Persistent Issues
If your refrigerator isn’t cooling properly after trying the basic reset steps, it’s time to call a professional. Watch for warning signs like the compressor running constantly but not cooling, making unusual noises, or shutting off repeatedly. These symptoms often indicate deeper electrical or mechanical problems.
A repair technician can properly diagnose issues with temperature control boards, start relays, or failed capacitors that home fixes can’t address. Many appliance technicians offer same-day service for urgent cooling problems.

Assessment for a New Compressor
When your refrigerator is more than 10 years old and experiencing frequent cooling problems, a professional assessment becomes critical. An appliance technician can determine if a compressor replacement makes financial sense compared to buying a new refrigerator.
Compressor replacement is one of the most expensive refrigerator repairs, often costing $200-$500 for parts plus labor. A professional can check if your warranty still covers the compressor, as many manufacturers offer 5-10 year coverage on this specific part.
Ask the technician about energy efficiency improvements with a new compressor. Modern replacements might reduce your energy bills enough to offset repair costs over time.
Preventive Maintenance and Tips
Proper maintenance of your refrigerator can prevent compressor issues and extend the life of your appliance. Regular upkeep saves money on repairs and keeps your food safely cold.
Regular Cleaning of Condenser Coils
Condenser coils play a crucial role in your refrigerator’s cooling system. These coils release heat from inside the fridge to the surrounding air. When dust and debris build up on them, your compressor works harder and may overheat.
Clean your condenser coils at least twice a year. For homes with pets, clean them every three months due to increased pet hair and dander. To clean:
- Unplug the refrigerator for safety
- Locate the coils (usually at the back or underneath)
- Use a coil brush or vacuum with a brush attachment
- Gently remove all dust and debris
- Wipe down the area with a cloth
This simple task can reduce energy consumption by up to 30% and prevent premature compressor failure.
Ensuring Proper Ventilation
Your refrigerator needs adequate airflow around it to function correctly. Poor ventilation forces the compressor to work harder, leading to overheating and potential breakdowns.
Leave at least 2-3 inches of space between the refrigerator and walls. Don’t place items on top of the fridge that might block vents. Check that nothing is blocking the toe kick vent at the bottom front of many refrigerator models.
For built-in refrigerators, make sure the installation allows for proper air circulation. Blocked vents can raise the internal temperature of mechanical components dramatically.
Check periodically to ensure furniture hasn’t been pushed against the fridge. This is especially important after cleaning or rearranging your kitchen.
Routine Refrigerator Care
Daily habits affect your refrigerator’s compressor health. Set the temperature correctly—between 37-40°F for the fridge and 0-5°F for the freezer. This prevents the compressor from working too hard.
Don’t overload your refrigerator. Cramming too much food blocks air vents inside and forces the cooling system to work harder.
Check door seals monthly by placing a dollar bill in the closed door. If it pulls out easily, your seal needs replacement. Damaged seals let cold air escape and make the compressor run constantly.
Clean food spills promptly to prevent sticky residue on door gaskets. Wipe down interior surfaces weekly with a solution of baking soda and water.
Defrost manual-defrost freezers when ice buildup reaches 1/4 inch. This improves efficiency and reduces strain on the cooling system.
Special Considerations for RV Owners
RV refrigerators have unique requirements compared to home units. When troubleshooting compressor issues in an RV fridge, owners need specialized knowledge about both power sources and travel conditions.
RV Community Resources
RV owners benefit greatly from community knowledge when dealing with refrigerator problems. RV forums like iRV2, RV.net, and RVers Online provide valuable troubleshooting advice from experienced travelers.
Many RV owners share their real-world fixes for common fridge issues. These forums often have dedicated sections for appliance problems where members can post questions and get solutions.
Facebook groups for specific RV models can also help with model-specific compressor resets. Some groups have thousands of members with extensive knowledge about particular refrigerator brands.
Local RV clubs often host workshops about maintaining RV systems, including refrigeration. These hands-on sessions can teach owners proper reset procedures and preventive maintenance.
RV Refrigerator Compressor Challenges
RV refrigerators face unique challenges that home units don’t encounter. Constant movement and uneven surfaces can affect compressor performance. When parked on an incline, refrigerant may not flow properly.
Most RV fridges operate on both propane and electricity (AC/DC power). Switching between power sources sometimes requires a complete reset of the compressor system. After power loss in a camper, many residential-style fridges enter “demo mode” and need specific reset procedures.
Temperature fluctuations in RVs are more extreme than homes. A compressor working harder in hot weather might trip and need resetting more frequently.
Battery voltage is critical for 12-volt fridges. Low voltage can prevent proper compressor function. Testing battery levels before attempting a reset can save time and frustration.
Limited space means RV fridge ventilation is crucial. Poor airflow often causes compressor overheating and shutdown, requiring a reset after cooling down.
Warranty and Manufacturer Support
When dealing with refrigerator compressor issues, knowing your warranty rights and how to contact the manufacturer can save you significant time and money.
Understanding Your Warranty Terms
Most refrigerators come with a limited warranty that typically covers parts and labor for one year. However, many manufacturers offer extended coverage specifically for compressors. These warranties often range from 5-10 years, covering just the part but not labor costs.
For example, LG refrigerators have been subject to a class action lawsuit regarding compressor defects. While LG agreed to cover replacement compressors for affected units, consumers reported having to pay for labor costs out of pocket. This highlights the importance of reading the fine print in your warranty documents.
Key warranty terms to look for include:
- Coverage period for different components
- Parts vs. labor distinctions
- Transferability if you sell your home
- Registration requirements to activate full coverage
- Exclusions that might void your warranty
Keep your purchase receipt and warranty documentation in a safe place for easy access when needed.
Contacting Manufacturer Support
When your refrigerator compressor fails, contact the manufacturer’s support team promptly. Most companies offer multiple ways to reach them:
- Phone support: Often the fastest option for urgent issues
- Online chat: Convenient for initial troubleshooting
- Email: Good for non-urgent inquiries or sending documentation
Before calling, gather your model number, serial number, purchase date, and a clear description of the problem. Take photos or videos of any error codes or unusual behavior to share with support staff.
If dealing with warranty service for an LG refrigerator or other major brand, be prepared to advocate for yourself. Request a case number for all communications and take detailed notes of conversations, including representative names and promised actions.
For persistent issues or warranty disputes, consider filing a complaint with the Better Business Bureau or your state’s consumer protection agency.
