I typically find it is not door hinge issues but door switch issues, especially with sharp. You may heve a little movenent in the door hinge and that is allowing the door hook to move up and down on the plunger for a door switch that is probably a bit melted due to bad connections. If you check the door switches and look for any browning around the terminals where the wires push onto the switch you will probably find an overheated connectoion. Replace the bad switch and run better wires and better termninals to the new switch and it will probably be fine.

Just replace the fuse Brother. No harm done. BUT, keep it away from your wife. Maybe she's thinking doubling the voltage would make it twice as fast. NOPE!!!

I'd try to unplug for a while. Could be a bad power cord for the microwave itself. I recently had a toaster problem. Bad wire right at the departure from the plug.

I would definitely suspect the door locking mechanism in this case. If it was the sensor it would start and then stop within a short time.

The starter switch should click if you have the door open and time it for 01.seconds and press start. So that is the secon component to think of.

This is a problem in one of the damper-related components, most likely the switch, but it may also be the motor or the damper door.

The damper is a door inside that opens or closes depending on cooking mode. If the controller senses that the door is not in the right position, it will shut down the cook cycle.

Sharp models stop after 59 seconds.

See the attached sample photo for a typical damper assembly.
