Panasonic NN-8501V Convection beeps on AUTO DEFROST when cold

I have to use a hair dryer to stop the AUTO DEFROST button from activating when the built in unit in my RV gets cold. I added a shutting vent to reduce cold but every night, even in relatively warm Yuma AZ in January, I must uplug the microwave or it will wake me with constant beeping and cannot be reset until it is warmed up. It usually takes me about 3 minutes with a hair dryer pointed at the touch panel to stop the beeping and get control to heat up my morning coffee. HELP! Do I have to replace the panel? If so, is it replaceable? Any other possible fix short of replacing the whole unit?

NN 8501V Panasonic Dimension 4 Convection/Microwave oven keeps blowing fuse

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead several seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

I got this microwave in my house, but its not working. all the buttons are not working accept stop/cancel button. please send me the sollution.

I have a similar microwave that I recently repaired. NN-9854 (bad capacitor). So your microwave functions but you cant stop it unless you unplug it, it ends its cycle, or you open the door? Does it beep when pressed? If not, you need a new control pad.

I have the same problem with Panasonic NN-8501V Microwave Oven

I took the touch pad control unit apart, clean the connector for the ribbon wire connection between the key pad and the control unit, reseated the ribbon wire in the connection. Everything worked like new.

RV Microwave/Convection by Panosonic Model NN-8501V, touch controls go crazy when cold, indicating the AUTO DEF button is in continuous contact. CLEAR/STOP only works for a second and then AUTO DEF starts...

I tried looking up the part number for this model and they don't identify clearly what the touch pad is. Would have to get one of the parts companys ( to do research on it.
I've done surgery on a few touch panels and it usually works out. Have to break through the plastic tabs holding it together, then you can clean the contacts. Then do something like find little tiny screws to fasten it back together.
Hope Ya Fix It!
