The appliance is making a loud buzzing sound when running, and it is not heating up at all. Everything else on the microwave works. The problem came on all at once. I’d appreciate any help I can get.
Thanks for the info. How do I determine which part it might be? Thanks!
Gene, I replaced the parts you recommended and there’s still no heat. How do you check capacitor? Should we consider replacing the magnetron?
Thanks!
