Microwave turns on for 2 seconds and then turns off. History: I changed out a blown fuse about six months ago but did not know at the time I should have changed the monitor switch. Last time it was dead and now it just turns on for 2 seconds. Any ideas what I should be looking for? Model #HMB5050/01 FD 9007100017 FCC ID ACLAP7A01
Does it run correctly with the cover off? On digital microwaves the clock chip is the
same frequency as the RF cooking wave. If the MW is leaking radiation they will only
run about two minutes as the clock doesn’t know to go up or down.
This is an inverter based system and therefore needs a somewhat different approach in diagnosing. Based on your description, toward the bottom of the chart, it may be DPC (control board) but I will tell you that I have seen harness issues cause that same error.
