Do anyone know why my smoke detector goes off and yet there is no smoke nor fire in the house?

Question

Why does it do that?

If the battery was low it would give off one ping every now & then.
But it going off like theres a fire or it sense smoke. Its annoying it even goes off during the night

Answer 1

It does it just to tick you off! It probably likes to do it the most around 3AM. Am I right?

All joking aside...

The most common cause of nuisance alarms on home smoke detectors is dust.

I would consider using a vaccum cleaner attachment on the unit. The can of air suggestion someone made can work good too. But not everyone has these.

Replacing the battery is never a bad idea if it's been awhile. But I've personally never seen a battery replacement fix a detector that was sounding falsely. Just the ones with the case of the "chirps", which is meant to signal a low battery.

Is the unit connected to other detectors in the house? Newer homes often include this feature, but the drawback is if one goes off, they all go off. So it can be tricky to find the culprit in a "false alarm" situation. If this is the case, you may have to clean them all. If that doesn't do it, I'd get one replacement unit and start "chaging them out" one at a time, until they shut up!

If it's a stand alone detector and cleaning doesn't do the trick. I'd just get a replacement and pitch the thing. I think it would be $10 well spent.

Good Luck.

Answer 3

Quell Smoke Alarms

Answer 4

Maybe it is detecting something you can't see. The sensor could be dusty; I think you can blow out the dust with "air in a can". Consider getting another smoke detector and see what it does.

Answer 5

I sometimes find that it is triggered by extreme heat or warmth. For example there is one located just above my bathroom door on the outside & as soon as I open the door after a very hot shower, the heat that comes out sets off the alarm.

Answer 6

if you have a good smoke detector..it may be detecting chemicals in your house.
For example oven cleaner sets mine off.
when we got a new dryer the first time we used it the chemicals they use to prevent mildew in the machine set the alarm off.
and once it was getting wet when the roof was leaking and it went off then.
also check the batteries they might be low.

Answer 7

I had this same problem, and it always happened between 2 and 3 in the morning.

I called the manufacturer and they suggested it was either dust or spiders in the detector and to vacuum them out. I did and haven't had a problem since.

Answer 8

Sometimes the sensors just go bad, you may want to replace it. If it was relatively inexpensive, they usually will start going bad after 5 years or so. If you can, you may want to get smoke detecters that are battery and hard wired into your electrical system. Those usually will not go bad.

Answer 9

Just replace it with a new smoke detector.

Answer 10

Check the batteries, they may be low. Another possibility, sometimes when I cook certain things mine go off. It is usually chicken that does it, when it is done in the oven, nothing is burning, nothing is smoking, it's just sometimes the oven gives off a scent I guess.
