Overload

The most comprehensive refrigerator compressor start relay and overload testing video on the internet. We show how to test a start relay for continuity and resistance, how to test the compressor overload, rattle test, and much more. When the start relay fails it will cause the compressor to not start and the refrigerator will stop cooling. You may also hear a clicking noise coming from the overload as the refrigerator tries to start the compressor. Some people call the start relay a start device, they are interchangeable terms for the same part.
