why it beeps so often if it shows 0.

We have a Carbon Monoxide and Gas Detector it keeps going off after being plugged in for a day and a half. Reset it it's good for about 36 hrs and it's going off again. Put in a new battery but that has not helped. They are not cheap!! We called the gas Company there was no leaks.
Asked by: 56NOMAD
It could be a bad unit. I'd return it to Home Depot and explain. If the second unit goes off, then there is a leak somewhere of carbon monoxide or gas.

Kidde Plug-In Carbon Monoxide and Explosive Gas Detector with 9V Battery Backup and Digital Display is rated 4.2 out of 5 by 113.
Rated 2 out of 5 by from Works fine but is pushing into the realm of “scam”... Works fine but is pushing into the realm of “scam” product. It is not at all practical to buy this for household use. Carbon Monoxide mixes (doesn’t settle, doesn’t rise), so it’s totally fine to plug the detector into an outlet. The explosive gases, however, do rise (quickly) and therefore this detector must be mounted within 12" of the ceiling to be remotely effective (it says so in the manual, not on the package). I don't know about you, but I don't have any outlets 7 feet or higher (like my vaulted ceiling kitchen with gas appliances I wanted detection for). Now, there is a power cord on the AC adapter plug, but that means I'd have to plug in the detector power supply and have a cord run up the wall where I then wall-mount the detector. Not only would this look terrible, but it wouldn't reach. I'm not using this in my house but do have confidence in using it inside my garage (where I have a propane heater).

Unit is located in my basement wanted a little extra protection since a new gas power vented hot water tank was installed and I have a gas furnace sitting next to it. I would suggest using this for extra protection

You have 2 options with this unit. It works with a 9V battery or 120V plug-in which I use as I do not want to worry about battery replacement.
