My 3 year old Whirlpool Over the Range Microwave was sometimes not detecting the door as closed (when it was) when I tried to running it. All it took was a couple of opens and closes and eventually it would register.

It's been like that for a several months and I never really did anything about it. However, the other day I got curious and thought it might be a sticky door latch, so as I kept the microwave door open I stuck a wooden pick in one of the door slots (top one) and I assume this activated the switch on the top only (heard it click in). I then realized my microwave now had no power at all (screen was completely off).

**Any idea what could've happened and went wrong?**

I am almost completely certain that the act of me sticking the pick in the top door latch is when the microwave went completely dead.
