Turn off beep?

I don't think you can. I see no sound button. Nor is there a code in the user manual suggesting such. At the bottom of page 12 in the user manual, there is a short description of what all the beeping is about. When a pad is pressed correctly, a beep sound will be heard. If a pad is pressed and no beep is heard,
the unit does not or cannot accept the instruction. The oven will beep twice between programmed
stages. At the end of any complete programme, the oven will beep ?ve times.

I don't think you will find the answer in the following: https://soundproofnation.com/how-to-mute-microwave/

Some microwaves have a sound button. Others may off the sound by pressing 0 or 1 a couple of times. Some have controls that put on a child lock, making the pad inaccessible, thus no beeps! If is another way to mute the sound in yours, a Panasonic tech would have to tell you. You might try their support. I just don't think there is that opton in your machine. https://www.manua.ls/panasonic/inverter-nn-st67js/manual?p=12

Hi.

To mute your microwave, start by checking the control panel. Look closely. The mute function may be labeled as a secondary function of one of the standard buttons. Check these things first:

• Look for a Sound button. Seriously. It may have been there all along, begging you to press it.
• Press and hold either 1 or 0. Sometimes manufacturers give these keys hidden, secondary functions.
• Press and hold the Stop or Cancel button. Like 1 or 0, this key might have a hidden function when held.

Often, pressing and holding 1, 0, Stop or Cancel will either result in turning off the beeping sounds or activating a child lock feature. (Child lock doesn't actually lock the door, but instead locks the control panel so no buttons can be pressed until the lock is removed by holding the button for around three seconds again.)
If none of these work, it's probably best to consult the manual. Even if you don't have a Sound button, there is no Mute function denoted as a secondary function or holding a button doesn't do anything, there is still a chance a mute function exists. It could be a button combination or, like on some microwaves, be buried in a submenu that's not at all obvious how to activate.
If you've tossed the owner's manual to your microwave, check the manufacturer's website. They will often provide a digital version of the manual as a PDF for more recent models. For an older model, you may need to do some digging, but a great start is to just do a Google search for "[microwave brand and model number] manual."
Once you have the PDF version of the manual, press Ctrl + F on Windows or Command + F on Mac to search the PDF for "mute," "sound" or "beep."


Good luck.

Some microwaves have a feature where if you hold the "Start cooking" button or something similar it will put it onto silent mode, this mode is generally for people who are cooking with others sleeping etc.

To turn this off you should try and hold the start button and see if this helps.

unplug machine. you will need to remove the cover. careful for the capacitor. usually after not running for an hour or so the capacitor will completely discharge on its own. looking at the back of the control board, you ill see a small round, usually black cylindrical part about 1/2 inch high with a hole in it. cover the hole with a couple small pieces of duct tape. this will mute the daylights out of it. to eliminate sound completely you will need to unsolder this part..

What make and model is it? Does it beep when you press other buttons, or is it always silent now? It could be the speaker if there is no sound at all. Or perhaps you accidentally set the microwave to a silent setting. Try looking in the manual or searching online for silent mode for your microwave model.

don't know if it's inherit or not to that model --you could check your manual and check with MFG on line or you could take a hammer to it---good luck

I had this mute problem and found that unpluging it for 1 to 2 min. and the problem cleared.

Unplug microwave, open top, "several screws" look to where the keypad is, behind that you should see the control board, mounted you should see a round black device may be a speaker or pizza buzzer, verify that is sound.

Hi, this is usually a bad touchpad. The way to tell for sure is to kill power to the unit, take the control panel down and unplug the ribbon connector that connects touchpanel to the clock. Put it back together and reapply power. The clock will just sit there blinking and, obviously, the buttons won't work, either. if the beeping stops, then the touch panel is bad. And If it still beeps, then you have a bad clock.

I have 2 possible solutions for you.
1) press and hold the 0 button for 3 seconds. This may only turn the clock display on or off, but may also mute or unmute the beeps.
2) unplug the unit for 30 seconds to a minute. Plug it back in and it should be reset.
