Compressor
When diagnosing a compressor that is not starting first verify that the contactor coil has a
minimum of 24 Volts. Verify the the load side of the contactor has 208 – 240 Volts when the
contactor is energized. Check the wiring to ensure the start winding is not tied into the same
leg of power as the common winding on the compressor.
