furnace thermostat set off carbon monoxide detector?

Can a defective wall furnace thermostat set off a carbon monoxide detector? The batteries went dead in the thermostat, we replaced them immediately. Scared us to death!!!

Answer
A wall thermostat is an electrical switch ( or a set of switches) so no a faulty t-stat will not trip your CO detector. DO NOT HORSE AROUND, if the CO detector is going off you need to assume the worse and call the fire dept, or a furnace contractor and get the furnace and hot water heater checked for a CO leak. CO can kill you , and is tasteless, oderless and invisible.

Carbon Monoxide Detectors?

Daniel D

I just moved into a new home that is all electirc. In my previous home I had natural gas, so I had a carbon mononoxide dectector. I just unpacked my old detector and plugged it in for the heck of it. It had a high reading of carbon monoxide. Is that possible or is it defective. Can I have carbon monoxide without having natural gas.

Answer
If there is no gas or fireplace in your home, I would look into the box that you moved it in. There are many chemicals that the fumes will mess with the sensor.
Take outside if possible and turn on, let set for a half hour to fresh air the sensor.
Also with the cold weather many people use fireplaces, if the humidity was high and no wind, many times the smoke or smoke by products i.e. CO will stay low to the ground and enter your home.
