This model does not have a brightness adjustment for the VFD display.

It may be a weak VFD tube due to aging or it may be that the rear of the display window and front of the display glass are very dusty.

Sometimes you can clean it inside to brighten it up.

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.

Then you can detach the keypad connector (as per attached photo) then remove the control panel screws.

Be careful not to crack the glass display when handling it, or it's a goner.

Then you can use a soft cloth (not a paper towel) and a mild cleaner (not ammonia-based) to clean the front surface of the VFD display glass and the rear side of the clear bezel (display window) that's attached to the keypad.

Some connectors have a lock.

We can replace yours for $74.95. Details are here.

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.

On these models, the LCD is connected to the main control board via a rubber connector known as a "zebra strip".

Sometimes the connections can get contaminated.

One can take the control board off and clean the contact surfaces of the board, the edges of the zebra strip and the connection side of the LCD glass with high-grade isopropyl alcohol.

See drawing below.

If you don't want to tackle this, we do it for $39.95 for customers nationwide.

Sharp R-1460A Timer counts down very rapidily and no heat


The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for maybe an hour.

Sharp Carousel Microwave R-1460A no power, door switch went first


You will want to replace the fuse and door switches. You will not be able to run it without replacing door switches. You do not need a new microwave. Door switches go bad, it has nothing to do with radiation.
