This week I’ve had two built in Kitchen Aid refrigerators with bad boards that need to be sent out for repair since Whirlpool no longer manufactures these control boards. Both had similar symptoms. KSSC42QMS03 pulsed the whole unit on and off, no cooling. KSSO42FTX02 pulsed only the evaporator fan on and off, cooling ok. Both had one bulging capacitor, see images below. Both evaporator fans had crazy high resistance, up into mega ohms (1400-1700 ohms is normal). So…are these things related? I think they almost have to be.
