Why is my refrigerator compressor so hot?
The reason your refrigerator compressor is hot could be because there's a lack of refrigerant, the temperature inside the unit is low, or a faulty sensor. Additionally, if your refrigerator is showing signs of a clogged compressor, it's either a problem in the condenser coils or in the internal temperature setting.
Can a fridge compressor overheat?
The most common cause of refrigeration compressor breakdown is overheating. In general, overheating changes the chemical properties of the refrigerant and refrigeration oils, leading to loss of lubrication and chemical decomposition.
How hot does a compressor on a refrigerator get?
The bulk of the heat is generated at the compressor discharge port. It's normal for this temperature to be as high as 300 degrees Fahrenheit, but it should never be higher. If the temperature rises to 320 degrees, the refrigerant will start to break down.

Once you’ve located the compressor on the back of the refrigerator, unplug the start relay from the unit and shake it. If you can hear rattling, the relay is bad and will need to be replaced. If you don’t hear a rattle, the relay is in good condition and the issue may be with the compressor itself.
Why does my refrigerator stop working?
When a refrigerator stops working, it is most likely due to an overheated compressor. Several factors could be responsible for an overheated compressor. This guide will help you to determine whether you can fix your overheating compressor on your own and when to contact a professional.
Why does my compressor overheat?
Similar to dirty compressor coils, a dirty condenser fan can cause the compressor to overheat by limiting the amount of hot air that is able to escape. If the condenser fan is broken, heat will become trapped in the compressor and cause it to overheat. You can clean a dirty condenser fan with compressed air or a vacuum cleaner, but you may have to replace the compressor if the condenser fan is broken.
