Mike for Model Number FRT21INGJD1 unit runs and cools fine but at times the compressor will not start. the inside blower runs but compressor doesn't. to start the compressor all you have to do is touch the ptc/compacitor which are connected together and plugged into the compressor. the compressor immediately starts and runs and cools perfectly. it will work hours or a day or two and the same problem. just touch the ptc/compacitor, you hear a slight arc sound or click sound and it starts right up again and runs perfectly. is this a ptc problem or a capacitor problem?
Answer Mike, It's not likely a capacitor problem 5304464438. Before you replace the PTC/Relay 218721108, you may want to unplug the power cord and check the wiring to the capacitor and relay for loose connections, and make sure the PTC relay is properly mounted and seated on the pins of the compressor. If all's OK, replace the PTC relay. Read More... Answered by AppliancePartsPros.com | Tuesday, December 29, 2015
