Does not heat and turnstarts at a normal speed then within 1 minute it slows down
With the unit not heating you will want to check the magnetron, WB27X10682, to make sure that it has less than 1 ohm of resistance. Also check for cracks on the magnet of the magnetron. That would be the most likely cause for the issue.
I have had to replace the switches several times (the small switches on the door latch). They seem to go out about every six months. This is getting kind of expensive. Is this a common problem? Any suggestions?
Answer Hello Dave,
The most common cause of these switches failing is when the customer using the door to stop the unit instead of turning it off with the button before opening the door. Give that a try and see if it doesn't extend the life of the switches.
