I'd highly suspect the control board with all the issues you're having. Turn table malfunctions can and are caused by either a control failure or a faulty door microswitch. However, since most of the issues you're having are low voltage circuits, it points to an issue with the control board. The Ewave units are NOT Whirlpool. They are Ewave. I would pull the board, check for ALL solder joints and/or burnt circuit paths. Make sure there are no cracked solder joints. Use a magnifying glass under bright light. Also, check the microswitches if you can. The no heat and no turntable could be a malfunction of one of the door switches. The one thing that is NOT controlled by a door switch is the panel lighting... this is why I believe you have a control board issue.
Are you referring to the lights on the microwave?
The door switches: There are usually three of them. You might check for a faulty connection, or you can pull the wires off (take a photo first) and do continuity checks. NO, NC, and COM are labeled in embossed plastic. Still, I think you have a main board issue because you're losing your display. Double check all the wiring for poor connections, and as I said, take the main board out and look for bad solder joints. You may find a faulty connection at the board low voltage transformer. This is what produces the voltage to close the relays. With all the problems of not heating sometimes and no turntable sometimes, I'd be suspecting a bad microswitch, but not with the display issue. Every symptom could be due to a faulty board though..
lets see if i can add a photo
I talked with customer service and thay fixed the isue bout paying you. Couild you please tell me if universalapplianceparts.com is a good source for boards and if model number will do to identify. I had trouble finding info on Ewaves using the model number from the unit itself.
On the washer which fills but won't cycle past filling. Its an analog so can't get a code. I open the door and used a screw driver to initiate door switch but nothing happend. Does it sound like a bad door switch or/and should I start a new question?
Sorry for the delay.. Holiday weekend and all. The part can be purchased following this link. http://www.repairclinic.com/PartDetail/Main-Control-Board/PKMPMSLA00/1206848?modelNumber=KOT151S
Yes, you would have to start a new question. We're only allowed to answer one question per thread. Site policy. However, I think you're on the right track :)
