Thermostats can be repaired or replaced when problems arise. You can thoroughly perform thermostat-related operations if you have the skills and knowledge to fix refrigerator-related issues. However, we recommend you return the damaged thermostat because if it is repaired, it is effortless to have the same problem.

Cooler door

The door with an open gasket will cause cold air inside to leak and infiltrate high temperatures from outside, resulting in the Koolatron cooler not cooling. You can change the door gasket easily. However, if the cooler doesn’t cool because you forgot to close the door, you can just keep the door closed.

Condenser coil

As you know, the condenser coil has to be cleaned periodically to avoid the accumulation of dirt. You use a vacuum cleaner or a damp cloth to clean the stains on the condenser coil. Don’t forget to disconnect the power when cleaning.


Compressor failure is a pretty severe problem. The compressor misused will very quickly be damaged. Therefore, when you detect issues related to the compressor, you need to repair and fix them immediately.
