There is really no way to do this without taking the oven apart and pulling the control board.

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

Works fine, except the beeps suddenly went silent. Examples: 1. When food is finished cooking, no beep any longer. 2. When pressing any key to set for cooking, no beeps any longer. Never thought that...

On page 21 of the owner's manual (online here), that's covered under "AUDIBLE SIGNAL ELIMINATION":

If you wish to have the oven operate with no audible signals, touch CUSTOM HELP, the number 2 and STOP/CLEAR.

To cancel and restore the audible signal, touch CUSTOM HELP, the number 2 and START/MINUTE PLUS.

How do I stop the beep when food is ready (it beeps if you don't remove at the food after intervals)? Sharp R-340

I too have Sharp microwave that constantly beeps at approximately one minute intervals if the food you have been heating isn't removed. It is loud, persistent and extremely annoying. I've opened the machine to try and find the loud speaker but cannot find it (it could be built in to the circuitry?). Any help on this would be appreciated. It's a very unfortunate design flaw on what is otherwise a very good and easy to use microwave.

I have a sharp r1480 microwave. the work lights do not turn on. the bulbs are good,and light buttons beep but no light.

listen for a click not just a beep, if it doesn't click the relay is bad on the pc board, if it clicks the trace may be blown to the relay

Own a sharp 7 E 53 (8) M Microwave;Oven and Grill. Last saturday I was defrosting bacon on lowest setting (Low) and microwave appears not to have worked since. Is there a sharp domestic repairer in...

Is it dead? (No lights, no beeps, etc.?)
