After replacing the door switches on my over-the-range microwave, there was a sound coming from the microwave like a low hum, not like when the microwave was running at full power, but like the magnetron was on low. Hitting "Cancel" didn't do the trick. An internet search turned up the suggestion that it sounded like one of the relays on the keypad panel was stuck open or closed, and that a replacement keypad circuit board was orderable. I ordered the part from partsimple.com, it arrived a couple days later and I installed it with no problem. No more humming and the microwave works great.
