model NN-SN966S Lost all control of the keypad exept Reset

First, out of the blue, the display screen showed the Power Level counting down repeatedly (P 10, P 9...) while at the same time the speaker was sending out a continuous beep, beep, beep.

When I unplugged the device for a couple minutes, then plugged the power cable back into the socket, the display came up flashing and showed 88:88. I pressed every button on the keypad and only the Reset button worked clearing the display and showed : and again none of the keys on the keypad worked.

Anyone have any ideas? I'm thinking maybe the keypad failed or possibly the microprocessor. Is this even fixable?

I, too, have this problem. Pressing Reset causes a beep and clears the 88:88 from the display. No other buttons beep or do anything.

Hi @dustinjarrett,

If it is "new" check the warranty provisions for the oven that are usually found in the user guide that came with the oven, as to what to do to make a claim for a manufacturer's warranty repair, replacement or refund.

That's what warranties are for.

From what I've been reading they are saying it's a faulty door switch. I'm going to check my door switch to see if that fixes the problem. This is my second microwave doing the same exact thing so might be able to fix both cheap.

Yes, Panasonic is aware of this faulty product, and has a solution. A chat with tech support today (9-12-2023) said "Yeah, those are symptoms of an internal component failing, unfortunately. Would you like me to look for a service center?"
My microwave, and dozens of other people's (read the unhappy 1 star reviews on Amazon) echo the exact same failure sequence. And they are not happy, because if it is out of the 1 year warranty-- so it's toast. For what I paid (over $350 with tax and shipping) it should have lived longer than 2 years and 6 months!

@flasharoo since there are no schematics for the keypads, it might be difficult to repair those. From what you are telling us, it sounds like a bad keypad. Of course, check it for any obviously failed component and post pictures. That way we might identify what may have gone wrong. 在已经存在的问题里加入图片
