In this video, I simulate common failures with refrigeration compressor electrical controls. The failure modes involve the relay going bad and exhibiting the following failure modes:
Not engaging the start winding.
Not disengaging the start winding.
Not disengaging the start winding AND overload relay not tripping.
The last of the three tests is destructive. The motor used was from a seized Westinghouse compressor. The winding insulation had already been damaged by moisture and sulphur dioxide attack. It was not a serviceable part, so no usable parts were destroyed.
