New Battery & Smoke Detector Keeps Chirping How To Fix

Venmo Tip Jar @AndrewDIY
There's a few steps you can take if your detector is still chirping even after a new battery.
1st, remove the battery.
2nd hold the test button down for 30 seconds.
if that doesn't do it open it up and clean the sensor surface with a qtip and a little rubbing alcohol.
If that doesn't work you may want to replace it entirely.
Good luck!

I woke up at 5 AM this morning to very loud chirping coming from two of my three smoke alarms. I blearily drove to the grocery store and bought three new batteries but two of the smoke alarms kept chirping. In desperation I went to youtube and stumbled upon your video and followed your instructions to a "T". I didn't even have to turn off my circuit breakers and now all three of my smoke alarms have stopped chirping. BLESS YOU ANDREW! (its now 7:42 AM and I can get back to bed.)

Is anyone else watching this video at 2am while trying to find those 9volt batteries you bought at home depot 6 months ago?

I just want to know why these faill only during the middle of the night.

This was the most helpful video I found by far for our issue. We replaced our battery yet the beeping continued the next day...? The answer was detach from ceiling, take out battery, replace battery, reconnect to ceiling, then test alarm with 1 quick press of button. After the press of the button the alarm cycled thru what looking to be a red light "test" with no sound, and after about 10 minutes peace was once again established in our humble abode... Hope this helps someone and once again thanks for the video, huge lifesaver! :D - Keep looking up!

After watching several videos I think you're the only one that actually knew what you were doing! No one else told how to reset either so thanks much!

[noahgraber]

you saved my life

Edit: never mind it's still beeping. Pro-tip: if it's still chirping completely disconnected it from power and deal with it tomorrow.

You did it! This really helped at 5:00am in the morning when two of mine went off. I had to look at another video to see how to REMOVE the smoke alarm from those wires, though. Luckily, that was easy to find, too. So comforting at 5:00am to hear a calm explanation of what you can do to fix your chirping smoke alarm when changing the battery didn't work!

Omg thank you!! Woke up at 5:30 am because I kept hearing this sound. It's so loud! I thought I was hearing a scared cricket or something!! Even googled "I think there's a cricket in my room" lol.

Thank you very much kind sir It is 4 am and I had been trying to deal with this shit for an hour and I can now experience the joy of silence

[jenniashley]

Thank you so much for having this out on the internet! It has saved my life and my puppy's life from anxiety! I got it fixed!

Thank you thank you thank you! My fresh out of the box unit with fresh factory batteries was doing this, and your recommendation solved it. Why the accompanying manual doesn't provide this information is beyond comprehension.

After changing the batteries in my smoke detector I couldn't figure out why it still chirped. After watching your video, I solved the problem. Thanks so much!

Thank you! I am a 62 yr old female caring for my 87 yr old mother recovering from a major stroke & living in a house with 9 & 10 ft ceiling; so alarming detectors are not needed. It wasn't batteries so now I hope these added steps (which I have now done on all 5 detectors) will provide uninterrupted sleep tonight. Thanks again!

THANK YOU! I was on a step ladder reaching all the way over my head to replace the battery. Couldn't SEE which way the battery was supposed to go in --- you showed me! Thanks! NO MORE CHIRP!

Your video was very helpful. My smoke-co detector was doing the three chirps. None of the other smoke only detectors wee sounding. I do believe the three chirps were the result of dust or dirt, even though the wording on the detector says to replace. This has happened once before and cleaning solved the problem. Thank you!

My poor husband unsuccessfully tried to solve this and made himself 15 minutes late to work this morning. The chirping persisted all day today, making my day extra eventful. This evening when he continued his "problem solving, " I suggested we Google it and here we are! Problem solved! Thank you, thank you, thank you for this video!

I suggest using a hammer, I have never had one beep again after hitting it with a framing hammer. Never fails to solve the problem.

Alternatively you can twist it to unlock it from the base, yank hard to disengage the wiring and throw it as hard as you can out the nearest window.

This is the method I use when they malfunction when I am sleeping, I always go back to bed feeling content and peaceful and fall right back to sleep.

A friend of mine has a method he calls "Ironic Justice", where he simply throws it into the wood stove. As the plastic burns it makes a lot of smoke, but it all goes up the chimney...

this was such a great and informative video and explained everything i needed to know especially at 4AM! Thank you!

[BecilBeatts]

Thank you for making this video, you solved my problem exactly. I would love to buy you a beer. I would have been changing batteries and beating my head against the wall for hours, and still probably not figured it out on my own, if it weren't for the Internet. Thank you.

Thank you, Andrew! YOU are a life saver! I thank you, my children thank you and my dog thanks you!
