Dan D for Model Number ZSC2002NSS01 HI Expert Help! Been trying to fix my microwave for a couple of weeks. Had a service guy out but not lots of help!! Started out, just went dead. Replace Magnatron Thermal and started working but Magnatron was on all the time even in clock mode. Replace thermal, overheated in 5 minutes. Transformer was buzzing fairly loudly as its on 100%. I have replaced the relay PCB board, transformer, Magnatron, Capacitor & diode and Thermal fuses. Have checked all the thermals & cermanic fuses. Service guy said 4 @ 8 amps coming out of Transformer. Everything seem to work but does not get hot. All I can think is the Power PCB board might be bad? Suggestions? Love your service and delivery. Buying a new Microwave piece by piece! :). Dan
Answer Dan, This issue will most likely be caused by a faulty main control board on the unit supplying power to the HV side of the system. Read More... Answered by AppliancePartsPros.com | Wednesday, March 22, 2017
