A microwave can be dead for many reasons.

The fuse is normally located on the floor of the chassis behind the control panel or between the door switches.

If the fuse is good, it may be an open thermostat or thermal cutout (TCO) / thermal fuse on or near the magnetron or on top of the cavity / body of the oven.

If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

When checking thermostats, if it has a hood fan thermostat, that should read open, as opposed to the others, which should read closed.

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

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

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

If it's intermittent or random, it may be a bad connection, usually on the control board or a loose fuse holder, or even an intermittent fuse.

You should do a continuity test on the fuse while it's in the holder (with the microwave unplugged, of course) then turn the fuse by hand or take it out and put it back in, then test it again.

If you remove the fuse, then press the meter leads against the ends, it can allow internal contact to be made and make a bad fuse appear to be good.

If you or someone you know decide to look into it, we have critical safety information and disassembly information at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

You have to replace the control board. Sharp has had problems with the display boards for awhile. There is no bulb or fuse you can change.

Stay away from Microwavedisplay.com and William E Miller. He will take your money and will not return your display unit let alone repairing it. Do your research. There are a lot of us out there!!!

Sharp microwave oven LCD display malfunctions


Might or might not work. IT worked for me.

This is a common problem. i havent completly solved it yet but this helps.


Be very careful doing this, There is Voltages with AMPERAGES high enough to boil your blood inside a microwave.

I had mine apart cleaning it. Only one number worked on my display. I wiggled and messed around with the wires in the back of the display. And almost every number in the display works again. Hope this helps.

Some of the lcds on the lcd display are not working on a sharp carousel R-490C(s) model microwave. Can they be repaired/replaced and is it economic?


We repair these for customers nationwide here in the US with our guaranteed $39.95 service.

I'm guessing you're in Australia?

We repair a few of these for Australian, UK, and Canadian customers, but the extra shipping is a factor in the choice to do so.

We have full details, plus critical safety, disassembly, and troubleshooting info at our site. You'll find a link to our site in our listing here on FixYa.
