Question about Sharp R-1870 Convection/Microwave Oven

1 Answer

Microwave Stopped Running

Unit is installed over the stove in a 2004 Monaco Motor Home. Very little usage(<5 hours total). Unit light comes on, and fans work but unit will not start. No front panel buttons work(ie defrost, auto cook etc. Timers will set but unit will not start. "Push start" instruction appears on the digital readout, but start button does not initiate a start.
Thank you for any assistance / advice that you can provide.

My microwave oven just stopped cooking. The light comes on and the Motor is running, but much louder than normal.


The magnetron in your microwave has probably gone out. The magnetron is the part of the microwave oven that produces microwaves. If you unit is a built in model, it will likely cost more to fix than a new one. Same thing goes for a countertop unit.

The extreme heat has opened up one of the thermostats / thermal cutouts (TCOs) in the oven.

If it was the bottom TCO or magnetron TCO, you should be able to access them by just removing the control panel.

But if it's the one on top of the cavity, the oven will have to come out of the wall, then you need to pull of the outer cover..

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download GE owner's manuals and installation instructions here.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

You should locate and look this over first.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

Microwave dead even though power works


It sounds like the magnetron overheated and opened the thermal fuse on the magnetron.

This can be caused when the internal cooling fan is not running or by a magnetron that is failing.

When I say internal cooling fan, I do not mean the hood vent exhaust fan which you can turn on and off manually.

I'm instead talking about the internal fan which comes on automatically whenever you microwave.

It is vital that the cooling fan runs, or the magnetron will be destroyed.

The magnetron will have a 5 to 9 year warranty. Your manual will tell you that.

If needed, GE may send you a replacement magnetron. GE Customer Service is here.

Microwave shut-off within 2-3 minutes


Why don't you return it? I think this is a common problem. We returned ours to Home Depot with no questions asked.

Blower motor on above stove microwave not running


The dual fan in the back is the vent / exhaust / hood fa. It will run when you turn it on, or if the stove top gets too hot.

The other fan is the magnetron cooling fan, and it will only run when you are cooking. If it is not running, your magnetron can be destroyed.

You can download GE owner's manuals and installation instructions here. That may help you a lot.

Please reply back with more details if this is not yet a FixYa...
