To reset a freezer compressor, disconnect the unit from power (unplug or flip the circuit breaker) for 5 to 10 minutes. This clears system faults and allows internal pressures to equalize. Restore power, then verify the temperature controls are properly set.
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.
Most freezers do not have a dedicated, physical "reset" button. Instead, you can reset the freezer's internal computer or clear system errors by performing a hard power cycle. Unplug the freezer for 5 to 10 minutes, then plug it back in to reboot the system.
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".
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.
12 Reasons Why Your AC Compressor Is Not Turning On
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.
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.
Here are a few tips to troubleshoot it on your own:
To reset a fridge freezer, perform a power cycle: unplug the unit (or flip the circuit breaker), wait 5 to 10 minutes to allow the compressor and control board to reset, and plug it back in. This clears minor errors and recalibrates the system.
Types of Common Freezer Problems
To quickly check if your fridge compressor is working, first listen and feel for vibration. If it is silent but hot to the touch, or making a rhythmic clicking sound, it is likely struggling to start.
Most freezers do not have a dedicated, physical "reset" button. Instead, you can reset the freezer's internal computer or clear system errors by performing a hard power cycle. Unplug the freezer for 5 to 10 minutes, then plug it back in to reboot the system.
Running an empty fridge for a longer period of time and having a lot of ice in the freezer chamber are oftentimes to blame. This can result in the incoming refrigerant in the compressor being both in a vapor and liquid form which is a mixture it is not designed to handle. Because of this, failure can occur.
Green = Run. The green run light indicates the compressor is running. If the indicator is dark it does not mean the unit is off. The compressor only runs when the compartment temperature is too high.
Resetting your compressor on your own
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.
To reset a deep freezer, power-cycle the unit by unplugging it from the wall or flipping the circuit breaker. Wait 5 to 15 minutes to allow residual electricity to dissipate and internal pressure to equalize, then plug it back in and set the thermostat to the desired temperature.
Reset Power
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.
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.
To test a freezer start relay, unplug the freezer, remove the relay from the compressor, and perform a visual/rattle test. Then, test for continuity using a multimeter. Replace the relay if it rattles heavily (if it’s a standard non-rattle style), smells burnt, or fails the continuity tests.
The very first thing to check when a refrigerator stops cooling is its power supply and thermostat. Ensure the power cord is securely plugged in, the outlet is active by testing it with another device, and the circuit breaker hasn't tripped. Then, verify that the internal temperature dials are set correctly.
The thermostat, sensing the room temperature, signals the relay. That signal tells the relay to either allow or block the electrical current to the compressor. When the thermostat calls for cooling, the relay closes, energizing the compressor motor.
