Beeper wont shut off - GE JVM1850 1000 Watts Microwave Oven

The buzzer is responsible for beep,it is mounted on PCB assembly,either remove the same or cut the supply sourse to it.

wither it fell out of place or needs replacement

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!

Is there a code "F3" in the display too?

That would mean the key panel (part number WB27X10467 key PCB assembly) is shorted.

The service manual is here if you or someone you know want to check it out and possibly do the work.

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.

I have the same problem, I'm trying to figure it out as we speak. I'll reply if I find anything out.

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 about 5 minutes. Then let us know if the hard reset does not fix it.

It's a safety device, mounted inside.

The beeper sound level can be adjusted.

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

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".
