The touch pad need to be replace, it is not so cheap but if you want to fix it you can order the panel and do it yourself just make sure the unit is off and the capacitor is grounded.
good luck

There may be an F type fault code on the display, or the display may reflect that a key has been pressed when it has not.

If you can supply more details along those lines, that can help in the diagnosis.

The rest of the answer assumes you have a failed keypad.

If you (or someone you know) might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

You can order Panasonic parts from Tritronics, but if you don't find what you're looking for there, try here.

Or you can find an authorized Panasonic servicer here.

If you would like to have us do this for you, we do that for $39.95 plus part costs.

Feel free to contact me directly (and please remind me of your model number) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Panosonic Microwave convection Model NN-8501V Touchpad appears dead


The unit has a fuse in the power board, but when the fuse is gone it does not even start up. If it starts it is not the fuse.

Look rather a problem with a faulty touchpad, or the magnetron that is not working and need to be changed.

Check also the door sensor.

PANASONIC Microwave Inverter #NN-SD697S. Everything works except the START button. Works sometimes, and not other times. Checked outlet, all was good.


This is either the door sensing switch (most likely) or a bad membrane switch [start switch] (that's what Panasonic calls it) on the touch pad. The contacts on the door sensing switch can be slightly contaminated and not read "zero ohms" to the control PCB. The control board thinks that the door is open and it will not allow the cook cycle to start.

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.

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 (andrewselectronics.com) 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!
