Panasonic Panel Problems

My Panasonic microwave randomly beeps and then the display shows "8" 1 - 4 times. This happens 1 - 2 times per day, seemingly at random. Nothing works until I push "reset" and then "8" again. What's the deal?

Re: Panasonic Panel Problems

Microwave works fine, it starts, heats and turns off when it is supposed to. When i open the door, it comes back on and the turn table also starts turning again. I am scared ( and not sure) when it does this, is it emmiting radiation. I am scared to reach into it, so i have to keep unplugging it to make sure it is off.

Re: Panasonic Panel Problems

Based on my 25+ years of experience, I would say the "8" key on the keypad is shorting, requiring a new membrane keypad.

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

I always recommend that users spray the cleaner on a soft cloth (not on the keypad itself) then wipe the control panel off.

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.

But of course, the keypad may be damaged or worn out, or control unit may be damaged.

Make sure oven is plugged into a grounded outlet, and that the outlet is actually grounded.
Although extremely rare, I have seen ovens where insects were walking on the back side of a control panel, and causing problems. Could also just be some sort of electronic failure.

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.

I am having a problem with my Panasonic Microwave oven. the operating panel is a touch type one. Now whenevr I am pressing any button, I am not getting any beep sound nor the display panel is showing any...

Hi and welcome to FixYa. I am Kelly.

This can happen when there is a power failure. Usually there is a PF in the display but you can also get 88:88

Try this first: Press stop / pause or cancel then clock and try and set the time. If at that time you do not get any beeps your control board most likely has a problem. To dig deeper if you wish to have more assistance I need your complete model number to possibly troubleshoot.

Thanks for choosing FixYa,

My microwave is possessed!

You have a shorting membrane keypad.

If and when an oven is coming on or doing anything by itself, this is very dangerous and can result in a fire.

So until it is repaired, please leave it unplugged or leave the door open when it's not in use, and please do not leave it running unattended.

FixYa's Web site is currently not notifying us when replies to our Clarification Requests are posted, so please reply directly to me with your full number from the tag on the unit and your oven's color so I can help you with free do-it-yourself tips and/or an estimate.

LG Microwave Beeps 3 times, display shows F3 and keypad dead.

Since it's less than one year old, it would be fully covered under warranty.

I'd suggest returning it to the dealer or contacting the manufacturer to get it fixed free.

For more Goldstar / LG / L.G. help, call 1-800-243-0000 (M-F, 7am-8pm CT, Sat 8-5 CT) and choose the appropriate prompt from the menu or visit here. You can get warranty info & find a local authorized servicer.
