Compressor Windings
Compressor Winding Resistance Check:
Remove the compressor wires from the AP1 circuit board. The wires red to yellow, yellow to blue & red to
blue should have readings from 2 - 4 ohms. There should be no reading from any wire to chassis ground. If the
readings between the windings differ greatly, the windings are bad. If there is a reading from any wire to the
chassis, there is leakage in the windings.

Red, Yellow & Blue Wires
Reactor
The reactor filters out electrical noise and transient voltage spikes to the control board. There will be a reading of
less than 1 Ω after the wires are removed. There should be no reading from either reactor terminal to ground.
