19.4.8 Compressor:
The following tests should be conducted before concluding the compressor is faulty.
1. Low and high side pressure, temperature of compressor, discharge and suction lines,
temperature of air leaving the evaporator compartment, temperature of condenser
coil, condenser fan operation, and amp draw at compressor.
2. Use a compressor start cord to isolate and test the compressor.
3. Use an ohmmeter to measure resistance / continuity at the compressor to check for
shorted or grounded windings.
a. Resistance between the “Common” and “Run” terminals: this will be the lowest
ohm reading obtained.
b. Resistance between the “Common” and the “Start” terminals: this will be the
mid-range ohm reading obtained.
c. Resistance between the “Start” and “Run” terminals: this will be the highest ohm
reading obtained (This should equal the combined total of the previous two
readings).
d. No resistance between any two terminals signifies an open winding.
e. Check continuity between compressor terminals and the compressor itself
(Scrape off a little paint on compressor to make sure that resistance can be
measured). If continuity is obtained, the compressor is grounded and needs to
be replaced.
