Compressor Crankcase Heater Resistance Check:
Unplug the wire connector from the circuit board. e resistance should read approximately 2.15K ohms. ere
should be no reading from either wire to ground. If readings vary from these measurements, replace the heater.

Reactor
Reactor Resistance Check:
e line reactor helps to smooth the inrush current , reduce harmonics and noise, and buers the system, pro-
tecting the electronics from transient voltage noise. e resistance between the coils will be very low, approxi-
mately .3 ohms and should not have any resistance to ground. You should disconnect the wires fro the reactor
before taking any readings.
