Microwave oven functions normal.

A buzzing sound is heard from what appears to be localized to a lamp relay area on the PCB.

The buzz sound is only present when the door switch is open and when the hood lamps are on. Note that the sound is lower when the night hood light is depressed.

I removed the lamps to see if the problem was related to current drain of the lamps. It was not related to current drain.

Seems the relay cannot hold and is chattering. It is possible to see a flicker/variation of the lights.

To workaround the problem, we turn off the hood lamps.

My guess is a PWB

Anyone else see this problem?
