Why does my GE microwave not spin and stay silent when I try to use it

Why does my GE microwave not spin and stay silent when I try to use it

When it was working anytime I set a amount of time it would spin and hum while it was heating. Every since the door stopped opening it doesn’t work anymore. If I set 30 secs it turns on the light and counts down but that’s about it

ANSWERS:

Sounds like a bad door switch to me.
