Looking at the schematic in the service manual here
, I would say relay RY6 on the small sub PCB (relay board) has shorted contacts.
That's the relay that runs both the fan and turntable.
It's possible that it may be a bad connection or driving component on that board, but in my experience, it's virtually always a stuck relay.
The part number on the relay as shown in the photo is hard to read, but it looks like "OJ-SH-112LM".
I should have one of these or I can point you to one if you want to contact me with the exact number.Feel free to contact me directly (and please remind me of your
full model number) for more information & help.
happy to help you with free advice and we'd appreciate your
thoughtful rating of our answer.
