Is a megohm test a valid test for checking an air conditioner compressor?

Yes. A megohm test is a way of determining the condition of the compressor's winding insulation. If the insulation is deteriorated or beginning to deteriorate, a megohm test will show this. Generally speaking, 20 megohms or less shows bad motor winding insulation. When AC voltage is applied to a compressor that has bad windings, it will likely blow a fuse as it will short to ground. Moisture in the system can cause a false megohm reading. Also, it is not advisable to test a system that is in a vacuum, as this also can cause a false reading. If a compressor is grounded, a regular multimeter set to ohms will determine this (one probe on any of the compressor terminals and one to the discharge or suction line pipe). A megohm meter will show that a problem is eminent even if the compressor is not yet fully grounded and blowing fuses.
