Making noise and night light flickering when oven is working

My microwave oven just started making a buzzing noise even when I'm not using. When I'm using it the night light flickers even if it is not on. I've changed the light bulbs, but didn't help. what else can I try.

The oven is still heating up and the turn table is fine.

Thank you for any advice.

There must be a short in the wiring between the bulb sockets and the power supply or control board. Otherwise the short may be in the bulb sockets themselves.
I would test the connections to make sure the wires aren't loose and all solder joints are tight. If all wires look good, and bulb sockets are tight, then the problem may be faulty capacitor

Are you talking about the light inside the microwave? The front vent I think will allow you to get to the bulb. Should be a couple of small scrrews holding the vent cover on, remove them take vent off. Start it up again and see if the light bulb wiring or socket is arcing

Yes! it sounds from your description you have a short in the system, the problem is caused by the inverter board or the magnetron, I suggest returning the unit because the alternative is a huge expence.

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.

Buzzing Microwave


the buzzing is the magnatron tube juicing too thousands of volts before emmitting the micro-wave radiation to what your cooking that turns molecules 180 degrees around... guess that friction is what really heats it.
radar ovens is what they use to call em and even people would stand in front of big ones to warm up long ago...lol canibles will love that.
