When you close the door the microwave turns on for 10-15 seconds. Opening the door stops it but closing again will cause the same result. The problem is intermittent. What parts should i check/replace to fix the problem?Thanks,
For model number FPMO209KFB
Hello Justin, thank you for your inquiry. We would suggest testing the relay switch, PartSelect number PS979520, for continuity. It also wouldn't hurt to test the other door switch, which is PartSelect number PS3409702. We hope this helps.

Microwave died so replaced the one fise. Plugged it in and it beeped but then when tried to use it, it died right away.

Hi Kris, thank you for contacting us. We would recommend testing the control board for continuity with a multimeter. If there is no continuity, replace it with part number PS2369251. If that does not take care of the issue, we would suggest checking the door switch, part number PS8769124, and thermal cut-out fuse, part number PS466969. Customer service is always available to help you place an order if you are having trouble doing so. Good luck with your repair.
All digital controls are working but when the door closes and l push start, the light comes on and the timer works but nothing else is functioning. Plate is not turning either.

Hi Wendy, thank you for the question. According to our research, the most probable cause of this issue is one of the door switches, part numbers PS8769124 and PS3409702. If any of these switches is faulty, you may need to replace them. If the issue persists, you may need to check the latch hook, part number PS11728390. We hope this solves your problem!

I first removed the top plate above the microwave door (3 screws), then I removed the plate containing the buttons and clock. The microwave has 3 relay switches and they are in a little holder. The holder was too difficult to remove so I just removed the bottom switch and replaced. The microwave started right up.
was told buy a repair person to check the door micro switches as it was a common problem. removed the top plastic air grill to get access to the screw that holds in place the control cover. After unplugging the unit, i took out the (2) screws that held in the switches and removed them (3). One switch was a bit melted so i tested it with a 12 volt battery and it was bad. Ordered a new one from Part select and got it fast . Works great .
After unplugging the unit remove the control face buy removing the screws. All three door switchs are on a bracket on the left. Remove the two screws holding the bracket in place and pull out. Disconnect the wires from the three switches and test each switch indivually to determine the bad one. I used a multimeter set on ohms.Replace the bad switch with the new one and replace all the wires. Reassemble the unit and you are good to go.
