Our 14 year old GE convection oven does this periodically as well, the magnetron doesn't engage in this case either, so I never thought too much of it. | ||

Sticky relay? Or faulty control board? I can't see any other possibility. | ||

You sure it's not just a cooling fan? | ||

 No MWO has ever operated the Magnetron with the door open, the way the door switches are designed it is just not possible.
In addition No One has ever been injured by microwave energy from a home MWO. They are one of the safest electrical appliances ever made.
I have seen many MWOs that have had the cooling fans run with the door open, and I have seen a few that have actually started when not called for with the door closed. If you have one that actually starts cooking without you starting it you should have it repaired or replace the MWO.

FYI, the 'chrome door' Radaranges have a very elegant monitor switch circuit that has always impressed me. Rather than the 'brute force' dead-short approach taken by other manufacturers (that requires switch replacement), in the RR, a wire wound resistor is placed in the circuit and a thermal cutout is run through it. The resistor heats up and opens the cutout within seconds but also limits current through the switch contacts. Being these machines were designed to be repaired, it makes sense Amana/Raytheon engineers would go to that level of trouble.
Today the only time I see a monitor switch failure on these is when a door spring breaks. For many of these RR's, it's the first time the cabinet seal has ever been broken. | ||
