Question about KitchenAid KHMS155LSS 1000 Watts Microwave Oven
After just a few hours of operation, we started to notice a faint humming/buzzing sound. It is a little louder when you open the door. Seems to be coming from the left side. All microwave functions seem to work AOK. Cooks fine too, but the high pitch is too much to bare. I tested the H.V. Diode and it checks out OK. Thanks!
I was going to suggest the low voltage transformer, but when you said it sounded like it was coming from the left side, that seemed odd. I have a stock transformer here I keep for test that is loud, but it works. Odd, eh?
