Question about Frigidaire PLMV168 Microwave Oven
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
