Nn-c855 microwave/convection oven suddenly started beeping and showing beef/pork in the middle of the night, can't reset it

Tried pressing reset which stops the beeping and the words showing, but no other buttons will work. The display just shows a : and it doesn't matter what I press nothing works. Tried unplugging it for a few days but as soon as I plug it back in it goes straight back to beeping and showing beef/pork in the display

SOURCE: keypad on microwave wont work

.
This may have already been dealt with, but others can benefit from an accurate, thoughtful reply to this problem.

Is it possible that some spray cleaner got into the controls?

I always recommend that users instead spray cleaner on a soft cloth then wipe the control panel.

Also, I always recommend non-ammonia cleaners since ammonia can crack and damage plastic.

Otherwise, the spray can get into the controls and lock it up or make it act odd.

If it does not dry out over time, it may need to be manually dried or blown out.

The keypad may be damaged or worn out, or control unit may be damaged.

SOURCE: Microwave/Convection Oven has mind of its own: turns to Crisp mode on its own.

Yes this is a touchpad issue. As you have noted the crisp button is stuck and this is the cause of this. You can try removing the keypad and push up the pressed button. If its jammed then replacing it is the only way.

SOURCE: My microwave won't turn on

I would try another rest buy unplugging ti for a couple of minute,s then plugging it back in.

If it still fails, the keypad may be failing.

Sometimes this is due to direct spraying of cleaner on the controls, or steam or grease.

In models like this, disassembly and cleaning is required.

We can do that for you if you like.

New unit used 3 days. Microwave beeps and screen goes to menu, or set time screen. Sometimes changes the date all by itself. Does this in the middle of the night all night long.


I advice you to contact service if it has guarantee. This seems to be a psychological problem about your oven(!). Technical person need to do an electronic research surgery on its board to see if there is any wrong thing.

Sharp carousel convection/grill/microwave maybe R990


Hello :

This happens because of a bad door switch . The plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door .

Check also the turntable . It could be out of it's right place .

WARNING :

1:Don't slam your microwave door because this may cause the fuse to blow and this is the reason of bad door switch problem .
2: A microwave is capable of giving you a serious electrical shock even when it's unplugged , so I recommend you to call a repair technician for help .

please don't forget to rate .

good luck .

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.

It sounds like you have a shorted pad ("defrost", maybe?) on the 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.

If you would like to have us do this repair 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.
