Sharp model smc1132cs disable beeper

Hello Friend, thank you for allowing me to assist you!

I see that your question is listed under Frigidaire microwave FFCE2238LW. Typically you will hear a series of beep once your food is done heating or defrosting has finished. For this purpose, the beeping signal cannot be deactivated and I show that the volume is not adjustable for your model. Most microwaves are preset to do this. Best regards! - Z

If the owner's manual does not mention this as an option, the only other option would be to disable the piezo beeper.

Here's a video showing you one way:

Reset it, disconnect the power cord by 1 minute and try again.

If this does not resolve the problem. the problem is control board.

God bless you

On some models, yes. Simply refer to your owner's manual to see if that feature is available on your model.

Otherwise, see this YouTube video.

Does the display say anything?

If it says "F3" then you have a shorted keypad.

Please post a new question with full model number and more detailed symptoms.

According to the owner's manual (available here), there is a beeper volume on some models in this series. If yours has one, press it and then press 0 to 3 to control the volume (0 mutes the beeper and 3 is loudest).

If your model doesn't have the beeper volume control it's just that the beeper is going bad. They sometimes do that, getting faint or quitting entirely. You can't get a replacement beeper from GE, only the entire control circuit board.

The beeper is a piezoelectric type. Radio Shack sells a variety of beepers. If you know someone who can replace electronic components, they may have one that could be used on the board. Changing the beeper for one not the same as the original would not affect the oven's operation or safety, so that's an option. I'd do that myself if I were repairing this for a friend. But you might not be able to get a professional service shop to do this because of liability concerns. They would most likely replace the entire board.

With luck, your oven just has the volume down. Hope this has helped, and thanks for using Fixya!

My daughter put the plate back in wet and the next thing I know it sparked and stopped working. Is it fried?

The beeper sound level can be adjusted.

Press the "BEEPER VOLUME" pad on the keypad, then select 0–3 for mute to loud.

Your owner's manual is here.

I have Kenmore microwave model 721.61820100.
It has an "Option" button. Press it. The display say "NUMBER"
Then press "1". The display should say "SOUND" and then "OFF".
Press "Start" and that beast turns silent, well not really, but the beeps are goooone.

If for some reason you don't like it this way repeat the sequence and the sound this time will turn "ON".
