Sharp R-9H84B-display black, cleared display shows "Conv Mix, 88:88 Auto". Short time all dark again. Hit clear happen 2 times then, all dark, no power, can't clear won't start, nothing works.

I would suggest pulling the control board out and looking on the foil side (opposite the component side) for "ring cracks," most likely on the low voltage transformer's connections.

The board may have the screen-printed reference designator "T1" near the low voltage transformer.

Also be sure the fuse is not easy to turn with your fingertips when it is in the holder. If it is, the fuse holder is too loose and must be replaced (not just squeezed with pliers).

You can order a fuse holder, part number WB06X10034 for $6.49 (subject to change) from the Pros here.

If you have any keypad issues, please note that the membrane keypads for this model have long been discontinued.

How do I replace the bulb for the display panel of a Sharp Microwave oven Model # R-314F ?


Normally switch power off and remove plug from wall socket, undo screws around side and back panel and remove outer cover, then the light socket will be visable so change light bulb and reassemble, CAUTION: high voltage may be present so best left to service person for safety

Re: Sharp carousel microwave oven minute display light out


Hello there
To replace the light you will first have to remove the outer shell.
To do this
(1). Remove all of the screws on the back of the microwave that hold on the shell
(2) Remove the screws that are on the bottom.

(3) now the shell should slide off towards the back of the microvave.
Note : this may take a little bit of pressure to get it off ok?

(4) Once the cover is off look towards the fromt of the microwave and
you will see the bulb. now just replace the bulb and reinsert the cover and the screws and you are all done ok? pretty easy ha/
best regards michael

The Display is Dim. Hard to read the numbers.


I have the same model and problem. The time display is totally unreadable. Looking for a solution as well. I suspect given the cost (I believe around $60), it's time for a new one. Anyone have any suggestions or easy repair ideas?

Sharp microwave oven R345 M 900 watts


In most cases the displays are protected by a low value resistor which could have burned out. First someone needs to determine if the display is getting the proper voltage. If it is and still does not work you need a display. If it isn't getting any power follow the circuit back to the power supply and you'll probably find an open resistor or micro fuse (which looks like a resistor).
