A refrigerator compressor is the heart of your fridge, responsible for circulating refrigerant and keeping food cold. If your refrigerator isn’t cooling properly, makes unusual noises, or stops running altogether, resetting the compressor may help resolve the issue. This guide explains when and how to reset a refrigerator compressor safely.
When Should You Reset a Refrigerator Compressor?
Resetting the compressor can help if you notice:
- The refrigerator is not cooling or is cooling unevenly
- The compressor won’t start or keeps clicking on and off
- Power outages or electrical surges occurred
- The refrigerator recently overheated
If your fridge is brand new or under warranty, check the manufacturer’s guidelines before attempting any reset.
Important Safety Notes
Before you begin:
- Unplug the refrigerator from the power outlet
- Avoid touching exposed wires or components
- Never attempt compressor repairs beyond a reset—compressors are sealed systems
If the compressor shows signs of physical damage or burning smells, contact a professional technician.
Method 1: Power Reset (Most Common Method)
This is the simplest and safest way to reset a refrigerator compressor.
- Unplug the refrigerator from the wall outlet.
- Wait 5–10 minutes to allow electrical charge to dissipate.
- Plug the refrigerator back in.
- Listen for the compressor to start within a few minutes.
- Allow 24 hours for the refrigerator to stabilize and reach the correct temperature.
This method resolves most temporary compressor and control board issues.
Method 2: Reset Using the Control Panel (If Available)
Some modern refrigerators include a reset function on the control panel.
- Keep the refrigerator plugged in.
- Locate the Reset, Power, or Cooling Off button on the control panel.
- Press and hold the button for 5–10 seconds.
- Release the button and wait for the system to restart.
Refer to your refrigerator’s user manual for exact button combinations, as they vary by brand.
Method 3: Reset the Compressor Overload Protector
The overload protector prevents the compressor from overheating.
- Unplug the refrigerator.
- Locate the compressor at the back or bottom of the fridge.
- Carefully remove the access panel.
- Find the overload protector attached to the compressor.
- Let the unit cool for 15–30 minutes.
- Reattach the panel and plug the refrigerator back in.
If the overload protector trips repeatedly, it may need replacement.
Method 4: Temperature Control Reset
Incorrect temperature settings can prevent the compressor from running properly.
- Open the refrigerator door.
- Set the temperature controls to OFF or the lowest setting.
- Unplug the refrigerator for 5 minutes.
- Plug it back in and reset temperatures to recommended levels:
- Refrigerator: 37°F (3°C)
- Freezer: 0°F (-18°C)
Signs the Compressor Reset Worked
- The compressor hums or vibrates slightly
- Cooling resumes within a few hours
- Interior temperature steadily drops
Full cooling performance may take up to 24 hours.
When to Call a Professional
Resetting may not fix problems caused by:
- A faulty compressor
- Damaged start relay or capacitor
- Refrigerant leaks
- Control board failure
If the refrigerator continues to malfunction, contact a licensed appliance technician.
Conclusion
Resetting a refrigerator compressor is a simple troubleshooting step that can resolve many common cooling issues. Start with a power reset, check temperature settings, and allow time for recovery. If problems persist, professional repair is the safest and most effective solution.
