It normally buzzes once every 30 seconds. Today it buzzes 3 times in a row. Does that normal?

I would clean out the battery cavity good and replace the batteries. Make sure you scrap any rust particles out too. I've always changed the batteries on a regular basis and all of the outside casing and what looks like a window on top.

Mine does not but I find buzzers distracting, so I don't mind. Plus, the machine's spinning makes some noise and I can tell when it's through.

The answers to your concerns are really good, it might be a bad unit. Like they said, call support line, check the water level. If it buzzes all the time I'd want a new filter. Good Luck

Idk but ours just started doing that too. My first one lasted 6 years and no ringing

I had mine for about seven months before that happened randomly, really annoying. It still does it.

I have had my unit for more than a year and use it on low most of the time and have had no buzz. just the normal fan noise

I haven't experienced this issue but I'm sure I will at some point. My issue is with a buzzing sound when pressing two keys down at the same time. Casio doesn't have a repair shop close to my house, the nearest one was an hour away so I didn't repair it. Good luck!

No, that is not normal, I have mine for two years. Are you sure it off and not just on the low mode, it is very quite.I believe there is a timer feature, make sure it is not set to go off automatically. Return it if it ahs a problem.

I have an older one, and this newer one I just got. The newer is certainly louder but it is just a buzz - no clanking, which can't be normal. I agree about trying to adjust that screw. As I recall, I had it on as I adjusted it and could hear the sound change. Good luck.

I have several of the units and there is not a buzz noise only a hmmmm like a fan. I think something must be lose in your unit. I can put mine on silent and I don't hear it at all...try that....if its still buzzing then something is wrong. They are great units.

Picked one up today and it does the same thing. They should at least mention it in the manual. I wasn't sure if it was normal. Apparently it is. Thanks for bringing this up and thanks for your follow up.

I think it beeps 3 times , stops and then will beep once every thirty seconds until you open the door.

yes it does, it just sometimes would countdown but not buzz. It wasn't consistent.

If it chirps every 30-40 seconds, the battery may need replacement. I can't recall if there is any "expiry" date on the detector - is it exactly 1 minute? I suggest tossing in fresh batteries and maybe clean by vacuuming around the detector with a brush attachment. And see if that stops the beeping? I thankfully have not had the chirping problem until after about a year and it was because the battery was weak. Is it all of them beeping at once? I would hardly think all 4 could fail at the same time, but try the obvious approach first. Otherwise, you may have defective detectors or your wiring may be faulty.

I'm not sure why it started buzzing after the power outage, but manufacturer told me to replace it if it starts to buzz.

In addition to 3 beeps the display blinks 3 times. The volume can be set to low or switched off completely. Thank you.
