I changed the relay switch because the microwave would count down but wouldn't heat. Now the microwave turns on automatically and wont shut off. Did i do something wrong?
Answer Hello Melissa,
This sounds like a door switch issue has occurred. The no heating needs to be troubleshot for since it can be a primary or secondary voltage issue. This can be the H.V. diode, the H.V. capacitor, the H.V. transformer, the magnetron, or the control board. More detailed diagnosis is possible with the model number from the units' I.D. tag.
Are all 3 switches on door the same?
Answer Rick, the top and bottom switches are the same, part number 5304440026, and the bottom is different, part number 5304468224. Thanks!
I believe I have a bad door switch. I see this one: Part # AP3769802 (in the picture it has this on it: D3V-16G-3C25). I have a total of 3 door switches. Does this one fit all three spaces? Or are there others? Thank you
Answer Hello Amy,
There are three door switches but they are not all the same. You will need one 5303319559 and two 5304440026. Note that the first switch listed is called a kit. This is because it includes the ceramic fuse that is commonly blown from the switches failure.
The microwave door will not open.
Answer Hello Panchito. You will need to remove the outer cover off the microwave and check for bad or broken parts preventing the door from opening.
