SOURCE: R-4H84 Sharp Carousel II microwave oven stoped working

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.

SOURCE: 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.

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.

I too believe that a "protection fuse" was possibly blown. It would need to be found and get replaced. Hopefully it is just a fuse and nothing else because the way it sounds to me, the microwave may be damaged.

Good Luck!

Are you talking about the light inside the microwave? The front vent I think will allow you to get to the bulb. Should be a couple of small scrrews holding the vent cover on, remove them take vent off. Start it up again and see if the light bulb wiring or socket is arcing

It is a logic problem or at least electrolytic capacitors that dim the display too far. The display could be repaired if it isn't a ic (logic) problem if it is then you need the whole display replaced

Display window dim


I would open it up and look at the connections to see if any can be replaced. Look for any darkened or burned looking connectors related to the display panel. Hopefully you won't need to replace the display panel circuit board but if you do. I would look for the cheapest replacement starting with ebay parts, and search engines for that specific part. Sometimes there are microwaves of different models with the same parts too!

Nn2555 display weak


In many cases , cockroaches are found to habit within specially when not used and can spoil the main board, panel display and connectors. Remove the front panel and board and confirm and if so you need to wash the board and reset. Also it can be due to failure of the display or drive from the board

Digital display of Bauknecht MCG 1731 micro-wave isn't readable in daylight.


If the microwave is workingg fine otherwise , then you can remove the display panel and see if there is dirt or insects that have clogged the display. Use a hair dryer to slighly warm the panel , check the voltage to the display panel from the main board and processor. If there is no issues here then it is possible that the display is weak and needs a replacement

Display not lit up


Seems like the display panel went bad. You can check for sure by unplagging the unit for 45 seconds and plugging it back in. If still no display order a new display panel.
Please rate if you are satisfied

No display on LCD panel on my whirlpool microwave


I do not know what procedure you used to replace the door, but if the buttons and display were working fine before you replaced the door then it seems that there is a plug not plugged into the control display panel. Other than that the low voltage power supply may not be providing the needed voltage for the display and only for the logic circuits which are a different voltage. With the microwave unplugged, take the cover off and look at all the connectors and make sure that they are plugged into something and none that are not plugged in. They should all go somewhere. To answer your original question, there is only one main fuse to the microwave. The circuitry in the control panel operates on low voltages +/- 5 volts or +/-12v so that part is not fused. What I recommend also is to go back mentally through the procedure you used to replace the door and that may give you a clue as to what you unplugged, although you should not have to unplug anything.

Display panel slowly fades out, then comes back on.


This is due to a bad connection which is interrupting power to the control panel. It may be a loose wiring connection prior to the control panel, a failing door switch, or a problem on the control panel. We repair the control panels for $32.50 nationwide. If you or a friend decide to check the wiring, the unit has a technical sheet inside which contains a wiring diagram similar to the one I linked here: http://207.234.2493.73/mwd/JVM1331W_wiring.jpg Also, you can find an exploded view and parts list by entering your model number in the repair parts section here: http://www.geappliances.com/shop/prts/
