Question about Panasonic NN-S251 Microwave Oven

1 Answer

Microwaved buzzed then fan came on

Hi,
I have a Panasonic NN-2501 (yes it says 2501) and just as the unit was finishing heating supper there was a loud buzz and then it shut off. The digital display was off and the range hood fan came on. I unplugged it and plugged it back in and the fan came on and no response from the control panel, not lights or anything. Was the buzz my magnetron going bad? it was built in March 1993. It is 13.0 amps so it is a 1500 watt machine apparently.
thanks
Mike

At that age, a magnetron failure would not surprise me, but I looking at the service manual, the only way the hood fan could be on is if its relay on the control board is on.

I would bet you have a problem on the control board.

I can help with that, but please feel free to contact me directly through our site link via our Fixya link at http://tinyurl.com/yzjozk

Panasonic NN-A755


It does sound like the magnetron is failing, when it shuts down it is because the thermal fuse is detecting to much heat from the magnetron and shutting it down, I might add this part is the heart of the system, rough cost would be in the area of $100.00 maybe cheaper. Intallation of this part is very tricky and there is the danger of high voltage, I recommend a pro for safety and correct installation.

Panasonic Microwave NN-C980-B buzzing noise but it still works.


All:
I have a 2003 Sears Ultra Wave microwave 721.63682300 with a similar problem. A few months ago it started giving off short buzzes when turned on. That stopped but then I noticed that everything took twice as long to heat up. After quite a bit of teardown&inspection I found a circuit break in the inverter board leading to ZD704 diode (pictured). I will now try to find a replacement diode to see if replacing will fix it. Thanks for your postings.

Replace the h.v. capacitor (the silver can mounted in back under the magnatron) and the h.v. diode and it will be fine.

Panasonic microwave buzzing noise


Yes, this is usually a shorted high voltage rectifier diode.

It is usually located behind the high voltage transformer and it attaches to the magnetron and to the chassis.

For ciritical safety links how to test the diode, see: http://www.gallawa.com/microtech/diode.html

It is possible that the magnatron is bad but hard to say on a no heat problem without checking all components. A lot of model give 5-7 yr warranty on that part.

Range light and oven vent fan


This usually indicates damage to the circuit board of the control unit assembly. We repair these control units nationwide for only $32.50 postpaid. If you decide first to remove or replace the bulbs or check the sockets or wiring, please unplug the microwave first. Failure to do that is usually how the boards get damaged. If you or a friend decide to work on it, we have *critical* safety and disassembly info at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can usually find helpful exploded view diagrams and order parts by entering your base model number (without the suffix) here: http://tinyurl.com/gv383 BUT - I don't recognize NN-2501 as a valid model number. Could you confirm that? Thanks!
