What is the proper procedure for checking an internal compressor overload?

To check an internal compressor overload, first, ensure the power is disconnected for safety. Use a multimeter to measure the resistance across the overload contacts; a reading of zero ohms indicates a closed circuit, while an infinite reading suggests the overload is open and may need replacement. Additionally, inspect the compressor for any signs of overheating or damage. If the overload is functioning properly, further diagnosis of the compressor may be necessary.
