Microwave will not start. When start is pushed it says open/close door press start. I does occasionally work when you try repeatedly but the problem is getting more frequent and with a lower success rate. I notice there are multiple door switches. What is your suggestion? I don’t really want to remove the microwave more than necessary. Thank you.
For model number MMV4205DH0
Hello David, Thank you for the question. We suggest testing the switches with a multimeter to see if they are reading open or closed. There will be markings on the switch to let you know what it should be reading. Also make sure they are properly seated in the holder. If you need help placing an order, customer service is open 7 days a week. Please feel free to give us a call. We look forward to hearing from you!

Ordered top & bottom micro-switches and mounting plate parts. Internet reviews could not find specifics if the issue was due to a top/bottom or combination of micro-switch or mounting plate failure. Pulled the plug. Removed the top vent assembly cover held in by 2 Phillips screws inside the vent. Removed the control panel held in by 1 P
... Read morehillip screw at the top vent assembly area. Lifted control panel upward to release the catch and moved it off to the side - didn't disconnect any leads. Used a Torx bit to remove the door switch mounting plates at the front and pulled the plates through the opening from the control panel. Documented the wire color code connections, the top plate uses 2 micro's with one using both the closed & open contact. Installed the respective micros on the mounting plates and worked backwards with the wiring and removal steps. Once completed, the open/close sensing has worked every time.
