Intermittent: Lower part of control panel, start, cancel, fan, light won't respond. Other numbers seem to respond correctly. Cycle pwr. No help. An hour later tried again and it worked. Sometime later tried again and no go. Very frustrating.

Hello LeRoy, thank you for your question. It sounds as if the control panel touch pad is failing. We would recommend replacing the control panel on this unit. I hope this helps.

This model smells like burning electrical. We had it unplugged and had the electrician come and check the plug and the wiring and all of that is good. Then we tried to plug it back in and it would not work at all. Two questions: Is there a fuse in this model? Can you think of any other reason why there might be an electrical burning smell? Thank 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.
