We regularly repair the circuit boards of microwave which are hit by storm surges, etc.

This repair usually runs $39.95 to $64.95, depending on if we have to replace the low power transformer. I just thought I'd mention this if you're interested.

But if you've decided on replacing it, the installation manual should be helpful in removing it from the wall. See it here.

Feel free to contact me directly for more information & help.

SOURCE: Sharp 1870 just quit cooking and no turntable

The fact that the microwave and convection both do not heat indicated that the oven is in demo mode, check the user manual, otherwise it will possibly be a relay not triggering, may need a pcb replacement, check Demo mode 1st....Phil

SOURCE: Sharp R-1870 stops at 59 seconds

Wow. I just read something ridiculous!

Well, never mind that, here's your solution:

This is a common 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.

We have the applicable service manuals for these models and have uploaded it to our site here and here to help you. You will need the free Adobe Reader to view or print it.

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.

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.
