Bob for Model Number Ziss480nxcss Compressor has problem starting shake a few time then starts and seems to work properly. The voltage on j15 is 12.5 v dc power supply board 120 in 25v dc out
Answer Bob, if the voltage at J15 was tested with the wires disconnected, the voltage would be good from the main control. As the inverter is receiving 120VAC, and the main control is sending the proper voltage, the most likely issue would be with the inverter WR87X29409. However, you may want to test the compressor windings to ensure they have not been impacted. With the power disconnected, the compressor pins will need to be tested to each other and should read 12.4 ohms of resistance on each set of pins tested together. If the compressor WR87X10111 windings should fail a resistance test, a licensed technician would be required to repair the unit. Read More...
