Sam for Model Number ziss480drjss I had to replace the inverter (WR49X10283) which is next to the compressor. It looks like the inverter was overheated as the casing near the compressor is brownish vs the original putty color. Now that the unit is working again, the compressor temperature seems very hot to me. I inserted a kitchen thermometer probe between the compressor housing and the inverter. After letting it sit about 15 minutes, the kitchen thermometer registered a temperature of 180F (about 83C). What is the ambient operational temperature range for the inverter WR49X10283? I am concerned that the compressor is hotter than it should be and the inverter will not last very long. Thanks so much. Sam
Answer Hello Sam, The temperature of the compressor should be warm as compared to room temperature. If the condenser fan is running and the hot coils are free of dust, and it is still running hot, it is an indication of a partial restriction of the sealed system. There isn't anything that can be done short of a sealed system repair. The filter/drier, heat exchange assembly, compressor, and evaporator would have to be replaced to clear the issue completely. Gauges can be put on the unit to verify that the low side pressure is too low and the high side pressure is too high but that is about all that can be done to verify that an issue exists. This would require a Freon certified technician since there are federal laws in place where Freon handling is concerned. Read More... Answered by AppliancePartsPros.com | Wednesday, September 4, 2013
