We have a Panasonic NN-SN952 microwave. After two years it has developed an intermittent power issue. It will power off completely and reset the clock sometimes after cooking potatoes and now it does it randomly. Opening and closing the door several times will often get it to power back on so we can use it. I have given up resetting the clock as it loses power so frequently. Could it be a door switch related issue or a thermal fuse issue, or something else?

It sounds like your magnetron is overheating and its thermostat is resetting.

Try it with a cup of water in one corner and see if that helps.

Otherwise, most manufacturers have a warranty of several years on the magnetron.

For info on that, visit http://www.magicchef.com/home.jsp

TO mdambros

You have a bad magnetron. We see this over and over.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

You'll save a lot by taking it in yourself.

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting.

TO guest (Panasonic oven)

The door switch you suspected is bad, and it must be replaced. They normally cannot be cleaned or burnished and be reliable.

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.

Replace the fuse with a ceramic fuse from Home depot! costs less than $3 and it will fix the problem. I had all the same problems as everyone else, you name it my microwave had it! you must remember replace it with a ceramic fuse! not a glass one. I know people say its the switchboard and all that nonsence but I promise you, the fuse plays a majoe roll in the microwave not working properly. Even though it doesnt look broken, a junky fuse can cause your appliance to do very strange things. I replaced mine 6 months ago and it works like its fresh out of the box.

SOURCE: Microwave beeping and F2 error code

hi,
The F2 code is a keyboard failure. Since it's intermittent I would check for a loose wire/connection. open the control panel and reset the ribbon cable on the circuit board....

Ken,
Usually there is an internal fuse and that is probably your problem. You will need to take off the outside cover of your microwave and then look where the power cord goes into the back of the unit. Look for the black wire coming out of the power cord and follow it. It should take you to the fuse. Hope this helps!

These early inverter microwaves blew their high current power transistors quite regularly. These high current power transistors are quite expensive to replace, and if one blows, there is a likelyhood of others blowing. As the microwave is over 13 years old, I'd suggest getting a new one. Inverter technology in microwaves is now a mature technology, resulting in reasonable prices and much improved reliability.

Faulty magnetron

I would contact Panasonic about this and tell them your story.

That is one way it can happen, but things just fail, too.

Otherwise, we servicers would not be in business.

You do need to be sure there is no grease or food particles stuck to the inside of the oven or stuck on or behind the waveguide cover.

You can call Panasonic at 1-800-211-7262 or visit here.

Panasonic NN-CS596S Convection Combi Steam Oven

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

Let us know if the hard reset does not fix it.

If it stops at 16 seconds and is a sensor model, it probably has a defective humidity sensor.

If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter or a bad magnetron.

If you do indeed have a problem, Since it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

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