There is no reset button on a refrigerator compressor. However, there is a self-resetting thermal switch that will turn the compressor off when it overheats. This thermal switch will reset itself after the compressor cooled down.
Reset your refrigerator
Follow the instructions below depending on your model and what you would like to reset: Reset your refrigerator: First, unplug it (or turn off the power at the circuit breaker), and then wait about five minutes for the electrical charge to clear out of it. Then, power it back on again.
However, refrigerator compressors last eight to 10 years, so consider springing for the extra money to replace them as they approach the end of their life span. Otherwise, another issue is more likely to pop up just a few months later, especially if you notice other signs that your fridge is dying.
Appliances do not have a reset button on them - to reset any appliance you UNPLUG the unit from the outlet for 3 minutes - plug back in - or turn off breaker to outlet and appliance for that long - then turn back on. That will reset the control computer board and reset the appliance.
Too Much or Too Little Load. A low load on the refrigerator's evaporator and a heavier load in the refrigerating chamber can both lead to issues with the compressor. Running an empty fridge for a longer period of time and having a lot of ice in the freezer chamber are oftentimes to blame.
Resetting your refrigerator compressor is a useful option for anyone looking to defrost their machine or adjust its temperature. A reset can also sometimes resolve other internal issues, like malfunctioning timer cycles, so it's one of the first things you should try if your refrigerator seems to be having issues.
Clear blocked air vents: Inspect the air vents inside the fridge and freezer compartments to ensure they are not obstructed by food or containers. Proper air circulation is vital for even cooling. Check the door seals: Inspect the rubber gaskets (door seals) around the refrigerator and freezer doors for damage.
But if your refrigerator seems to be “running” all the time, then the appliance is working too hard. While having a refrigerator that works overtime might give the impression the appliance is especially robust, it's actually an indication that something could be wrong with your refrigerator parts.
The location of the reset button on your compressor can vary depending on the model and manufacturer. Typically, it is located on the motor or near the motor housing. Look for a small red or black button that is often labeled “reset.”
For your typical, U.S. home combination refrigerator - freezer, the thermostat in in the fridge box. The fridge box temperature is what turns the compressor on and off.
Flip the switch to the off position and wait at least 5 minutes to allow the refrigerator to completely power down. Turn the switch back on and allow the fridge to recalibrate itself. You should hear the compressor and fans running, which indicates that power has been restored.
One of the most common causes is a lack of lubrication. The compressor relies on oil to keep it running smoothly, and if the oil level gets too low, the compressor can overheat and break down. Another common cause of compressor failure is a build-up of dirt and dust.
When your compressor doesn't kick on, one common culprit might be a faulty pressure switch. For instance, if the pressure switch is stuck in the open position, it may not send the necessary signal to the compressor, preventing it from working as expected.
Without a regular cleaning, the coils can become clogged with dirt and dust. This prevents the efficient transfer of heat from the refrigerant to the air, causing the compressor to work harder and fail prematurely.
Depending on the model, this may take more than 24 hours, so be patient. If your compressor will not start again, try adjusting the controls to colder settings to see if it will start. Wait for some time, as the refrigerator could be in the midst of a defrost cycle, and the compressor won't run when it is defrosting.
If the start capacitor is defective then the compressor may not start. Check for signs of overheating or arcing and replace if necessary. If the overload, start relay and capacitor check ok, then you may have a defective compressor which should be checked by a qualified technician.
Try resetting the control panel by turning off power to the refrigerator briefly. Unplug the refrigerator or turn it off at the circuit breaker for 30 seconds to reset the control.
There are several causes for a refrigerator that doesn't cool, including dirty condenser coils, poor ventilation, improper installation, faulty or dirty gasket seals, unorganized food storage, appliance location and malfunctioning internal parts.
A refrigerator compressor replacement costs $700 to $1,250 on average. Most refrigerator compressor prices are $200 to $400, depending on the brand and size. The labor cost to replace a refrigerator compressor is $500 to $850. The cost to repair a refrigerator compressor is $50 to $125 per hour.
