Question about Panasonic NN-T990SA Microwave Oven

1 Answer




   John here, My aunt recently passed and we where cleaning her house for resale. I was given the oven and I pluged it in before we took it out of the house and seamed to work fine. We set it up in the house and used it for 3 days , everything worked fine.   Until we tried to re heat osmething and when you push the start button and release it it would work fine for 3 minuter and turn off? When you keep your finger on the start button it will cook. My solution I unpluged it and it worked for 1/2 a day and started the same thing again. I remember working in a nursing home where they had a oven that you had to put a code in it to work it. Could this be one of them? I got from the monitor read out on the unit that it had a child lock on it.


  I didn't get a n owners manual with the unit, so I am a little lost. As I said earlier I only went with the read ont on the unit.


           Looking for your help>John

    bought ours at a garage sale for $20 so it doesn't owe us a thing. Worked fine for about a year - then got cute! Like going to Vegas - sometimes you win and sometimes you don't. First it works fine. Next time it shuts off after about 3 seconds and says to read the manual. Haven't got the manual. Tried going through the functions and resetting all. It will work again once - and then nada. Unplug - reset the time - and it might work once. Might not. Any ideas? Tired of going to Vegas.

It sounds like a probemI with the inverter.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here:

I have a Panasonic NN-L829BA Microwave. I need to replace the door release button - it broke in half. I can't find a part on the web. Can you assist?

I had a handle break and I had to buy a new microwave. You usually can't find parts for smaller appliances on line or at a hardware store. Is it under warranty still? See link below.

Operates for 3 seconds on microwave then stops

If the digital programmer circuit / controller does not get a feedback signal from the inverter for a period of 3 seconds, the controller will stop the cook cycle.

It could possibly be as simple as a loose connection in that area. The repair shop your friend used may not have been Panasonic-authorized.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer.

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