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. If it gets hotter than 350 degrees, the lubricating oil inside the compressor will start degrading.
If your compressor is running hot to the touch it’s a problem you should take seriously. For example, if you notice scorch marks on the walls behind the appliance you should disconnect its power source immediately. This poses a fire hazard and a danger to your family.
Why is my refrigerator compressor so hot?
A compressor can run hot for a variety of reasons, including lack of refrigerant in the appliance or a refrigerator thermostat that is set too low, thus causing the compressor to work too hard. Check your refrigerator thermostat to be sure it is set at an appropriate temperature.
How do you know if your refrigerator compressor is bad?
You’ll know that your compressor is bad when it starts making abnormal noises, the compressor overheats or not providing proper cooling, or when the fridge compressor clicks on and off too frequently.
What happens when refrigerator compressor overheats?
In the worst-case scenario, an overheating and buzzing fridge compressor can cause a fire.

Can a fridge compressor explode?

What causes an air compressor to overheat?
If the air vents become clogged or are pushed up against a wall, the compressor will become overheated over time. Make sure during installation that your compressor is placed in a proper location and regularly clean the compressor’s air vents over time. If a thermal valve starts to fail, overheating can occur.
Can a compressor overheat?
An electrical problem outside of the A/C also may cause a compressor to overheat, such as voltage issues or spikes in power. If the compressor is short-cycling, this also can cause overheating. The problem might be due to a dirty air filter or evaporator coil, or a faulty capacitor or metering device.
