Itmay be the fuse, which is usually located behind the grille or on thefloor of the oven behind the control panel or between the door switches.

Ifthe 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 / bodyof the oven.

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

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

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.

Ifit goes dead or blows the breaker (or GFI) when you plug it in or open or closethe door, then there's a problem with a door switch or door switchmount.

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

While we don't have that exact manual, we do have a similar service manual here which should be close enough to help you or someone you know troubleshoot these basics.

Once you know what's wrong, the best place to order Sharp parts is Tritronics.

There's no power to my sharp LC24LE240E. I've checked the fuse and power outlet and both are fine. Any ideas??


It may be a thermal fuse. There is a thermal fuse in most modern microwaves that will kill the unit if something gets too hot in the cavity. Sometimes the magnetron thermal protector can shut down the unit. check them both for continuity.

I have a sharp r-1460a Carousel Oven...outlet is good but there is no power...not even the clock. I want to replace the fuse first ...I have the control panel loose. where do I find the fuse?


you must be very careful as the result could end up with trip to hospital , 1) the main fuse should be fitted within the plug , 2) there are 2 other quick break fuses sited next to the transformer ,but please be very careful , if you don't know then get some one who does ,

I have a Sharp Model 1460A Microwave. It quit working while warming something up yesterday. Outlet is good. No power to unit at all. No light working, etc. Is there a fuse that I can check to see if it...


Dead appliance, power on wall outlet.

YOUR SAFETY IS PARAMOUNT!

Attempt this only if you are competent.

If your appliance has absolutely no functions at all, remove it from the mains supply, remove the case and see where the mains lead goes in to the appliance and follow the cable until you find the main fuse.
ONLY USE THE SAME TYPE AND RATING OF FUSE TO REPLACE IT.
The usual cause of this fuse failure is the door switches are contaminated or sticking. Check the door switches before putting power back on to the appliance.
Hope this helps.

Built-in Sharp Carousel II Microwave Convection Oven died.


There are a couple of safety thermostats in the oven to shut down power if something overheats. One is on the magnetron tube (the microwave source), the other is on the cooking cavity. These sometimes go bad. There's also a power line fuse that may have failed, or become loose in its mounting clips. These can be tested with an ohmmeter; they should all measure very close to zero ohms if they're good.

Another possibility is that the control circuit board in the oven may have failed. I have worked on several Sharp ovens where the power transformer for the board has gone bad for no good reason. If the board goes bad the oven may appear to be dead as well.

Microwave servicing is best left to professionals. If you're thinking of keeping this one, take it to a service shop (or call for home service) and get an estimate. Then decide whether to repair or replace.

Hope this has helped a little. Thanks for using Fixya!

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.
