I removed the battery from mine. When I put it back in, the timer blinks with a click sound 'ULUnt'. What does that mean? Do I need another battery?

I have no idea. My problem was different. Once the battery was in, the countdown timer option kicked in and could never be turned off. Sent it back to Amazon. This model is different from an earlier model, both of which worked fine. This later problematic model also has a beeper which is also silent. Like, why did I buy this thing?

i've no clue, but i found they don't like being dropped in water either. i got a chirping sound every now and then and eventually got tired of the noise and bought a new one.

I would take the battery out...let it sit. Then after 5 minutes put back in and see if it works OK...

Hmmmmm... check for mice?!?! Just kidding. I have no idea why the safe would do that. Mine has never made a sound, and I cant imagine what part of the mechanics would even be capable of making a clicking sound. I don't think there is any kind of "low battery" warning. My safe has functioned perfectly for years. Did 'Stack-On' customer service have any thoughts?

See if there is a plastic tab that is preventing he battery from making contact. If it has one you may have to pull it out. If it's not that then it's just because the unit is likely defective. It's a super cheaply made unit.

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.

Pressing the start/stop button stops the timer from running, but the numbers still appear. Other than popping out the battery, I don't know how to turn that part off. I leave mine on, to that extent, and haven't yet had to replace the battery - it doesn't seem to go through them very fast.

When you insert the battery It makes some "clicking" noises a couple of seconds. Try a different battery, you might have a bad battery or bad charger. If you only have the battery that came with the set, return the whole set and get a new one. When returning remember to specify "it doesn't work", otherwise you might have to pay for the return. In case of doubt how to return it and get a replacement, call amazon's customer service.

Mine does this but the yellow light is blinking. Don't know why but unplugging it and plugging it back in fixes it... until the next time. :-/

Just went through support for this problem. The guy asked me to remove the batteries and then click the left and right button fast, alternating between them for 10 seconds or so. I felt like an idiot doing this, but surprisingly it worked. Time will tell if comes back.

It sounds like your item is defective. The timer should always be running and advancing. Hope this helps.

me too!!! mine started blinking last year - after i took it apart and cleaned as the manual instructed. Put it away for about 4 months - took it out last week, yep,,, still blinking.

I didn't know what it was for either until one day the light fell off my head in a dark crawl space and I had to go looking for it in the dark. Then I was very thankful for the red blinking light. Also, I think it is to let you know that the battery is not dead.

I agree with the other comments about it probably being a bad battery. This timer should run for a very long time on one battery. I'd try a new battery before going through the hassle of returning this timer. These are great timers, and they are hard to find in stores. If a new battery doesn't work, try e-mailing Polder directly and see what they might do to help you out.

Seriously ? Mine never stops unless I power it off. The only thing I can think of is something with the timer setting. Maybe you have the timer set to go off every few minutes. Can you get a stopwatch and get some data on the intervals of on/off ? Maybe unplugging it will reset it if it is for some reason set by the timer option. If that doesn't reset it then perhaps it is malfunctioning. It definitely sounds like timer related.

You almost certainly have a bad battery. I own several of these timers, and the batteries last for many months even with heavy usage of the various features. I believe the clock mode is running in the background all the time and you cannot turn that off.

If It Isn't Doing Anything Then Your Batteries Are Probably Dead. I Went To Walmart To The Jewelery Department Handed Them The Old Battery & They Gave Me New Ones..Just Add Soon As You Install The New Batteries And Put It All Back Together It Should Automatically Come On. Mine Did Not Have An On/Off Switch. I Just Took The Batteries Out When I Was Done.
