Smoke/Carbon Monoxide Detector went off last night with blue

Customer Question

Smoke/Carbon Monoxide Detector went off last night with blue light flashing. What does that mean? I turned off the furnace and opened the windows after verifying there was no smoke or fire. We pulled the battery (which is only five months old). There had not been any chirping and the alarm tone was different from the fire alarm tone. We attempted to blow dust or spiders from the alarm and then it set off all the house alarms. Any ideas.

Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

If there was no smoke or fire then it could have been a carbon monoxide alarm. Given your description you need to have a tech come out and check out your heating system before you turn it back on.

Ok. Thank you for your quick response. What sort of Tech. HVAC or electrician?

HVAC tech, if you have a hot water or steam system then you should call a plumber
