Question about Panasonic Microwave Ovens

1 Answer

Microwave oven no. NN-A514 cuts out when cooking

Microwave oven no. NN-A514. Trying to cook a jacket potato and the microwave cuts out for 10/15 minutes, then becomes live again. Same thing happens when we start trying to cook again. Screen is blank, buttons unresponsive. When it regains power, it's like you're using it for the first time - put time in etc...

I had that issue and I opened the unit and there was a fuse near where the power went in. Went to the small local hardware store and they ordered it. It was well under $5 (can't remember) but it still works over 10 years later.
If the fuse blew again I would have trashed the unit.

It should default to the high power level without your having to select that.

But if you think it may have a problem, you could unplug it for a few minutes then plug it back in and try again.

After that, if it's not acting as it should according to the owner's manual, it may need service.

If so, since it's under warranty, I would let GE fix it.GE Customer Service is online here.

SOURCE: Fire in Microwave Using Sensor Control for Potato

Please contact your home insurance to have the problem logged as a failure of the microwave. The insurance company will most likely help you with the smoke damage to the house and will contact the manufacturer to get their money back... there might be an issue with the manufacturing of these appliances.

SOURCE: Panasonic Model NN T964SF inverter

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.

In most cases, this is a problem with the inverter or a bad magnetron.

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.

SOURCE: Panasonic Microwave Model NN-S454 glass tray does not rotate

I would suspect that you have trouble with one of the door switches or its mount.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If the switch mount is broken, it's usually more economical and safer to add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

If you only need a switch, you can order a universal type here for $5 postpaid.

You can order other parts for this brand at Encompass (formerly Tritronics). Or you can call them toll-free at 866-779-5835.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases in about a week or so.

Sometimes when cooking dry foods such as popcorn, potatoes, etc. there can be some reflection back to the magnetron, which will cause overheating.

Try it with about 1/2 cup of water on one corner of the cavity.

That load may be enough to keep it from reflecting microwaves back down the waveguide.

Shuts down on potato button only

Not much info to go on here. Are you putting in the number of potatoes vs.the cook time? Most microwave potato functions would not read "5 minutes." It would be read as a request to cook 500 hundred potatoes.

Fuse blows on microwave switch on

one of three things shorted could cause this: H.V. diode,capacitor,or the magnetron tube, take screw driver and short terminals on capacitor before touching anything inside the case, then chk resistance on capacitor should show infinite after needle settles, diode should show hi resistance one way and a lower resistance in the other direction(use the RX100 scale not the RX1) on both parts diode should not show very low resistance or it could be leaking,mag is a different story,it can be chk'd but in a different way

Did I blow it up????

After washing you need to poke holes in potatoe skins or the steam can cause them to explode. Cook potatoes no longer than 6 to 8 minutes depending on your units power.

Microwave ovens can be very dangerous if damaged, so you will be safer to replace the unit. Better safe than sorry. Service on microwave ovens is not cost effective, and the newer ovens are very reasonable.

I have a new microwave MSE 23 i bought it 1 month ago. It has been working fine maybe use it 6 times a week. I put jacket potatoes in tonight when i went to get them out they had not cooked but felt...

If your microwave oven is ONLY 1 month old and there is any question with its performance, it should still be under warranty from the manufacturer so I would bring it back to where you purchased it and have them provide a replacement of have them demonstrate that the one youi have is working to spec. Conversely, if you put large potatoes in the microwave, they havea lot of mass to them and will need to cook for quite a while.. Have you tried anything else in there of smaller proportions and those did not cook? You should be able to boil a cup of room temp water in a minute or two.. If that fails.. bring it back..

Hope that helps
