We had the same problem, and the service technician quoted over $300 to fix it. My wife found this thread online (click on link below) and after following the advice here ours is now fixed for a total cost of under $40, and that included a new soldering iron (see below)!

The problem is either the damper motor or the damper switch. You can order both from Tritronics and ours shipped un less than a week. It is not possible to tell which it is without disassembling the microwave, so I ordered both. In our case it was the switch (one of the electrical contacts was black like it had burned out).

Read all the advice about discharging the capacitor; I would recommend downloading and printing out the service manual (especially page 18 which is an exploded parts diagram which helps you identify what is what (click on link below)

Page 14 is also useful because it gives you the part numbers to order from Tritronics. The two items you may need are 1-11 Damper switch and 1-22 Damper motor.

The space is rather tight, and you need to be very careful you don't cut your hand on the sharp (no pun intended) metal. It definitely helps to remove the long mounting bolts that runs through the space. Be very careful when disconnecting the electrical connections: the little metals tabs they use on the ends of the wires break very easily - hence the soldering iron. The most difficult piece is undoing the screw on the right hand side that secures the motor; it's just cramped and you need a very small/short phillips screwdriver to get to it. I would advise removing the switch first (it's secured by a couple of little metal tabs) because then the cam which drives the damper door will be able to drop free when you remove the motor. Finally, when installing the new motor, make sure that the tab on the cam wheel is correctly inserted into the little slot on the bottom of the damper door.

As I said above, read all the advice on the other thread and the general advice on working around microwaves on the web site. It's all good stuff. Good luck!

It sound like the antenna behind the plastic plate may be warped and touching the cavity. From my experience when they start shooting sparks it is time for a new microwave.

Sharp carousel microwave convection oven keeps blowing fuse

The service manual is here:

You can get Sharp parts from Encompass here.

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead several seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount.

Sharp R-1850A Mocrowave Convection - No power

Chances are if the internal fuse and magnetron thermostat are good, then you have a circuit board that needs repair.

You can probably find exploded views at the Sears parts site. If you find a bad thermostat, the best place to order Sharp parts is Tritronics.

We regularly repair these control panels for customers nationwide (RV owners & dealers, too) with our guaranteed $39.95 service.

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