I've had the same CO detector in my home for many years now, perhaps more than 7 years. The lights work (both POWER and CAUTION) and every time I press the TEST button it lets out the loud beep that it should when CO is in the air. My concern, however, is whether or not the detector is still as functional as it was when it was purchased.
Granted, I've been using the same smoke detector for 20 years and it seems to work A-OK, but are CO detectors any different?
Answer
There is a certain life expectancy in smoke and CO detectors. I read in a technical bulletin they last about 7 years. Reason is, sensitivity parameters change through the years. Put your mind at ease and install new units, also change batteries when we set our clocks ahead and back. (Easy to remember)

Carbon Monoxide Detector went crazy this morning?

I have a new Kidde NightHawke Carbon Monoxide detector. We got it about a month ago and it has worked just fine. I live in Ohio and we are in the midst of a winter storm so we have had 5-7 inches of snow and the temp is around 5 right now. This morning as I was leaving I glanced at the CM detector as I always do and it was rising from 30 to 33 to 36. Now normally it sits at zero. I woke my husband and let him know as I left and called our furnace tech. It never went higher than 36 and eventually went back down to 0. We have gas heat, water tank is gas. Nothing else is gas in the house. We were running an a small electrical heater in the laundry room to keep the pipes from freezing, could that have caused this? What else would cause this?
The reason this concerns me so much is we have a 19 month old.

That is Dangerous.
I would keep an eye on it. If the detector is near a furnace vent I would check the detector when the furnace first comes on. Sometimes with a cracked heat exchanger it will build up some CO when heating before the blower fan comes on. That will give a rise on the reading at the start and then it goes back down as the air mixes in the house.
If you get more readings on the detector, you definitely need the furnace and water heater checked.
