Remove the wiring from the three terminals before testing. 2.
Measure the resistance of common and run.
Measure the resistance between common and start.
Typically three to five times the resistance of to . 5.
Measure the resistance between start and run.
If to and to equal to then the windings of the compressor reading the proper resistance..
If to and to measure resistance of infinity and to has measurable resistance the the internal overload of the compressor has tripped.
If this is the case the compressor will most be hot to the touch and will need to cool down before the compressor can be restarted..
With the wiring still removed from the compressor terminals test the resistance of each terminal to ground.
