I have a Whirlpool GMC305PDQ2 Combo microwave/oven. When I push start, the microwave will run for 3 secs, and shut off. I push start again and it will do the same thing... If I keep pushing start, it will start running fine and complete the cycle. Sometimes it will run just fine.

I do notice that the word 'door' briefly shows up on the control panel when it shuts down.

1. How can I access the door switches to test them?

2. Reading in here it could be the magnetron leaking RF. How can I test if the magnetron is leaking RF. If I run at 0 power, is the magnatro on at all??

Thanks,
MikeB.
