How do you reset the compressor on a refrigerator?

Author: scraper  |  Last update: Thursday, July 16, 2026

To reset a refrigerator compressor, perform a hard power reset: unplug the fridge (or flip its specific circuit breaker) for 5 to 10 minutes. This allows the compressor’s internal thermal overload switch to cool, clears error codes from the control board, and resets any compressor timing locks.

Do refrigerator compressors have a reset button?

No, there is generally no physical reset button on a standard refrigerator compressor. Instead, the compressor relies on a built-in "overload protector" designed to automatically cut power if it overheats or draws too much current, and will reset itself once the motor cools down.

What is the most common cause of refrigerator compressor failure?

The most common cause of refrigerator compressor failure is overheating. Overheating places extreme thermal stress on the motor and internal moving parts, ultimately leading to mechanical seizure or motor burnout.

How to get a refrigerator compressor to kick on?

Starting a fridge compressor depends on whether you are simply resetting the system, replacing a failed starter component, or attempting to hotwire it for testing purposes. Follow these safety precautions and step-by-step instructions.

How long does it take for a fridge compressor to reset?

Wait it out: Leave the refrigerator unplugged for 5–10 minutes to allow the compressor to fully reset. Listen for the click: When power is restored, you should hear the compressor kick back on within a few minutes.

Is there a reset button on a refrigerator compressor?

Will unplugging the refrigerator reset the compressor?

Yes, unplugging a refrigerator will reset the compressor, as well as the main control board and sensors. This simple power cycle forces the system to reboot, which often clears minor software glitches and allows the compressor's internal thermal overload switch to reset.

Where is the reset button on a compressor?

The reset button is almost always located on the electric motor itself—usually on the side or back near the terminal box. It typically sticks out as a small rubber-covered or exposed black/red button, sometimes labeled "Circuit Breaker".

What would cause a compressor not to kick on?

12 Reasons Why Your AC Compressor Is Not Turning On

  • Dirt Buildup in the Compressor. ...
  • Expansion Valve Issues. ...
  • Loose or Disconnected Terminal Connector Parts.

Is it worth fixing a compressor on a refrigerator?

Whether fixing a refrigerator compressor is worth it depends mostly on the age and cost of the fridge. Compressor replacement typically costs $500 to $1,200+ for parts and labor. If your appliance is over 8–10 years old or the repair exceeds 50% of the cost of a new fridge, you should generally replace the appliance instead.

How do I know if my fridge needs a new compressor?

If your fridge is making loud clicking noises, constantly running without cooling, or failing to turn on entirely, the compressor may be bad. You can confirm a failing compressor by checking the electrical pins with a multimeter or observing the motor's physical behavior.

What is the most expensive thing to fix on a refrigerator?

The compressor, coils and control board are the most expensive repairs. Your fridge's brand, model and size, plus your location, will impact repair costs. If your refrigerator is more than 6 years old and it will cost you more than half its original price to repair it, consider replacing it instead.

What is the number one cause of compressor failure?

The most common cause of compressor failure is overheating and poor lubrication, often triggered by a lack of preventative maintenance. When a system runs too hot or lacks proper oil, internal components wear down rapidly, leading to mechanical breakdown.

How do I do a hard reset on my refrigerator?

To hard reset a fridge, unplug the power cord or trip the circuit breaker for 5 to 10 minutes. This clears the main control board, recalibrates internal sensors, and resolves cooling or display glitches. Once the power returns, reset your temperature settings.

What is the average life of a refrigerator?

A refrigerator's average lifespan is 10 to 15 years, with a median of about 12 years. However, exactly how long your unit will last depends heavily on its style and maintenance.

How long should I leave the fridge off to reset it?

To reset a refrigerator, unplug it for 5 to 10 minutes. This duration ensures the internal capacitors fully discharge, allowing the control board to reboot and clearing out temporary electronic glitches or sensor errors.

How to force a fridge compressor to turn on?

Reset Power

  1. Unplug your refrigerator. If the plug is too hard to reach, switch the circuit breaker off.
  2. Wait 5 minutes before returning power to the fridge.
  3. Once power is back, open your freezer and push the light switch 3 times to trigger a cooling cycle.
  4. Monitor temperature over the next 24 hours.

Is a 7 year old refrigerator worth fixing?

Bottom-freezer refrigerators should be repaired within seven years and considered for replacement after that. Top-freezer refrigerators should be repaired within three years, considered for repair within three to six years, and replaced if older than seven years.

What is the life expectancy of a refrigerator compressor?

A refrigerator compressor typically lasts 10 to 15 years. With diligent maintenance and ideal operating conditions, some can even reach 20 years. However, because the lifespan of the compressor often matches the lifespan of the fridge itself, many units are replaced entirely when the compressor fails.

How to fix a compressor not turning on?

6 Troubleshooting Options When Your AC Compressor is Not Working

  1. Check Your Power.
  2. Check the Air.
  3. Check the Terminal Connections.
  4. Look for Dirt Buildup.
  5. Check the Capacitors.

How to check if a compressor is not working?

Diagnosing a bad compressor involves listening for strange noises, feeling for lukewarm air, or performing a multimeter test. The most telling physical signs include the compressor failing to turn on, tripping your circuit breaker, or showing visible oil/refrigerant leaks.

Will a bad capacitor cause a compressor to not turn on?

Yes, a bad capacitor is one of the most common reasons an air conditioner compressor will not turn on. The capacitor acts as a battery, providing the necessary jolt of electricity to kick-start the compressor and fan motors.

How do I reset my refrigerator compressor?

To reset a refrigerator compressor, perform a hard power reset: unplug the fridge (or flip its specific circuit breaker) for 5 to 10 minutes. This allows the compressor’s internal thermal overload switch to cool, clears error codes from the control board, and resets any compressor timing locks.

How do you tell if your compressor is locked up?

A seized AC compressor means the internal pistons, scroll, or bearings have locked up completely. Common symptoms include a loud squealing or grinding noise, a burning rubber smell from a slipping drive belt, the serpentine belt snapping, the AC blowing warm air, or the engine stalling when the AC is turned on.

What is a reset compressor?

A reset can help clear any errors and get your system running again. Additionally, if your air conditioner fails to start or keeps tripping the circuit breaker, it might indicate that the compressor needs resetting. This reset process can often resolve minor electrical issues without needing professional intervention.
