Reverse Phase
Activated
0.8 A 0.7 A 0.8 A
Condenser fan stops. Reverse phase
selector relay is energized and
condenser motor is started in reverse for
2 seconds. Amp draw difference
between correct and wrong motor
rotation must be less than 0.2 amps.

F1.06
Compressor Test
Activated
7.1 A 7.0 A 7.1 A
With condenser fan on and compressor
on, compressor is operated at 25%
capacity. Amp draw is measured and
compared to voltage. Evaporator
temperature and condenser coil
temperature are measured and stored.
NOTE: If the condenser
temperature is below 15 C (59 F),
the condenser fan remains off for
this test.
