Panasonic Inverter Microwave - Platter motor buzz and dim light when idle
Subject:
Panasonic NN-S563WF S/N: 6B43180461 Mfr Date: April 2003 Problem: The platter motor buzzes or vibrates (no visual motion) and the interior light has a very faint glow when the unit is in idle. Otherwise the microwave works fine. In checking a few components, I found what appears to be an encapsulated wirewound resistor under the main transformer that tests open. I know someone else on here tried testing the high voltage diodes unsuccessfully as they seem to require a high forward bias voltage. However, since the microwave works, I don't think there is a problem with the diodes. Does anyone have a schematic? What is the component under the transformer? I would like to avoid replacing the whole board as that seems such a waste. I really hate the way electronics have become "disposable". Has anyone come across this "vibrating/buzzing motor" problem?

Welcome to low end...so called state of the art electronics! All this
is normal for this unit!

Thanks for the feedback. The real slap in the face is that this was not a
cheap microwave and I bought two of them (one for the travel trailer) The one in the trailer has seen little use and does not buzz - go figure. Why can't at least one major electronics comany have consistency in quality?! Sheesh! I'll check for a leaky component. When the door is open the buzz goes away (and of course the light comes on) so you may have a good idea with a door switch.

I have an Inverter but my light does not come on when door is open, a real pain for me. Is this normal?? greg Bruce wrote in message roups.com... check for leaky door switches and leaky relay on the control panel Bruce H wrote: Subject: Panasonic NN-S563WF S/N: 6B43180461 Mfr Date: April 2003 Problem: The platter motor buzzes or vibrates (no visual motion) and the interior light has a very faint glow when the unit is in idle.

It´s not normal. You should get your bulb replaced, or better yet,
smashed. |
