Base Pan Heater Check
Base Pan Heater Resistance Check:
Unplug the wire connector from the circuit board. e resistance should read approximately 740 ohms. ere
should be no reading from either wire to ground. If readings vary from these measurements, replace the heater.
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.
