Will not turn on says door

The door interlock switches require replacement.

broken or misaligned door interlock switch is most likely

The switch assembly is somehow staying "closed" satisfying the interlock and enabling it to run.
Disassemble the unit, beware specially of the high voltage capacitor, if you aren't comfortable or competent, buy a new microwave. If you are mechanically inclined, disassemble the unit until the switch assembly is accessible; it will have the door latch attached to it.
The switch is either broken or something? exogenous is keeping it closed. It may have come loose due to the door slamming?.
It's a simple fix. I am certainl you will be successful.

The door switch is adjustable. one or more need adjusting to solve the problem

PLEASE CHECK THE DOOR SWITCHES, REPLACE DOOR SWITCHES

This sounds like either a bad door switch or possibly a latch head problem from taking the door apart......

this is dangerous; replace or adjust your door switches the interlock switches should only allow you to turn on the microwave when the door is closed
