My carbon monoxide detector keeps going off, why?

Kelly D

This detector is about 12 years old. The brand is a Kidde Carbon Monoxide Alarm. Well about a week ago it just randomly went off. I changed the batteries, and about an hour later it went off again. Not me nor my parents felt any symptoms of carbon monoxide poisoning but we opened all my windows and I shut off the hot water heater thats right across the hall from the detector just to be safe. We just thought its the detector messing up because its so old but we dont know for sure. Anyways the next day after it went off we turned the hot water heater back on and the detector didnt go off untill today which has been a week since it last went off. But we have a newer detector that plugs into the wall right underneath the old one and it hasnt went off. So is the older detector just too old or should I call the fire department! And also has anyone else had trouble like this with their carbon monoxide detector.

Answer
A carbon monoxide detector that is that old is probably malfunctioning. I'd unhook it if you have a newer one installed.

carbon monoxide detector going off?

Sophie I

so itll beep twice and then wait 30 seconds inbetwee. im home alone, i called my dad and he said it was fine so i should ignore it.... help?

Answer
- Replace the battery, if this didn't stop the beeping then take it outside your home and wait 5 minuets.

If the beeping stopped then you have a CO issue inside your home, and if it didn't stop then your CO detector is malfunction and needs replacement.
