That would probably be a bad secondary interlock (bottom door switch) or its mount.

We have the full service manual for this model and have uploaded it to our site here to help you.

You will need the
free Acrobat Reader to view or print it in case you don't have it.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If you only need a switch, you can order a universal type here for $5 postpaid.

My Sharp Carosel volume got really quiet. Is there an easy fix?


If you are referring to the beep when you press any function,the beeper on the board may have failed.
The two other sounds are :i. there is a fan that comes on when start is pressed and, ii. the other sound is a heavy hum also when start is pressed.This comes from the transformer and maybe the magnetron tube. If you are not getting these sounds then troubleshoot these areas,careful though, the output voltage from the transformer is about 1.5kv

THE STOVE TOP LIGHT ONDER THE MICROWAVE BLEW OUT. WHEN I REPLACED THE BULB BOTH LIGHTS NO NOT WORK.


Sounds like a power source issue from under the hood.
Unplug or turn off all power and take a closer look in there,. alternatively - this may sound crazy, but are you certain both bulbs are working by testing in another fixture??

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 model R-1870 Carosel quits cooking at 59 seconds


This is a problem in one of the damper-related components, most likely the switch, but it may also be the motor or the damper door.

The damper is a door inside that opens or closes depending on cooking mode. If the controller senses that the door is not in the right position, it will shut down the cook cycle.

Sharp models stop after 59 seconds.

See the attached sample photo for a typical damper assembly.

We have the applicable service manuals for these models and have uploaded it to our site here and here to help you. You will need the free Adobe Reader to view or print it.

If a switch is all you need, we offer a universal type for only $5 postpaid which you can order here.
