Question about Microwave Ovens

1 Answer

Panasonic NN-S533WF Microwave

Manufactured in 2003, purchased in 2003-2004. Went to heat some leftovers, unit runs about 23 seconds then stops, does not beep when it stops. Does not heat at all. Unplugged for 2 minutes, reset clock, tried to heat again, shuts off 23 seconds. No beep when it shuts off. It will keep the correct time. It will not go into child lock mode. Most likely cause, worth fixing or not?

    Since I am in no way a repairman for microwaves, ballpark figure on the cost of taking this to a service center for repair?

  • Anonymous Nov 16, 2007

    it is the magnetron. to fix mine, it cost about $55 for labor plus $5 for shipping for a total of $60. the part was still covered under the 5yr warranty.

    Mine does the same thing. Is it worth pulling apart to fix? What price might parts be? (I have had a quick look inside but there was nothing obviously blown/damaged.)

    I have the same problem too. Runs for approx 30 seconds and then just stops and produces no heat.

    I'm thinking about replacing it with a toaster oven.

Panasonic microwave problem help needed

Dan, That unit has an inverter, that is the power source for the part that puts out the Microwave energy called the Magnetron. The inverters are expensive and I stopped doing warranty work for Panasonic beacuse of them. Some pencil pusher somewhere though it was a great idea to replace 3 common fairly inexpensive parts. with that dang inverter. Microwaves have come down a lot in cost, I would buy a new one without an inverter. Sorry, wish I had better suggestions, I DO NOT LIKE THEM. LOL Sorry! Panasonic and their distributors are always out of them and there so expensive no one wants to stock them. I have had new ones sent to me that were already bad.

Comes on for 5 Secs

Hi I am Vortash sounds to me as if the Magnetron is burning out and the heat sensor switch is turning the unit off as the mag gets hot ? .. you can get a cheap replacement of ebay but to be honnest microwaves are so cheap now you will probably get an oven for what you would pay for a new magnetron .. Regards Vortash

Microwave runs for about 20 seconds then shuts off.

My mother had the same problem and she was going to trash it. Me being an extreme environmentalist, dint wanna let it go to the scrapyard. Got it down to Mumbai India checked with the engineers down here and rectified it. Problem was with the Magnatron. You would need to replace it. Well this one's getting repaired and off to a institution in need like the Home for the Aged rather than some scrapyard.

Shuts off after 23 seconds....

In most cases when the microwave stops @ 23 seconds it's the Magnetron which has failed, and is shorting to earth.

Either that or the magnetron isn't getting the right signal from the inverter board. It gives it 20 seconds to get the right signal or it shuts itself off.

My Panaosmic microwave model number NN-S543 just stops after running for 23 seconds. It was running fine for the past 5 years and suddenly yesterday this problem starred. Even the 23 secconds it runs there...

The 22 seconds is the giveaway.

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.

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