Compressor Crankcase Heater Check - Gree Neo GWH09MA-A3DNA3A Installation, Service & Troubleshooting

Reactor Resistance Check:
The line reactor helps to smooth the inrush current , reduce harmonics and noise, and buffers the system, pro-
tecting the electronics from transient voltage noise. The 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 from the reactor
before taking any readings.
Compressor Crankcase Heater Resistance Check:
Unplug the wire connector from the circuit board. The resistance should read approximately 2.15K ohms. There
should be no reading from either wire to ground. If readings vary from these measurements, replace the heater.
