Why is My Carrier Furnace Blowing Cold Air?

The furnace is the heart of your home. It plays a vital role in the keeping you and your family comfortable all year round. Quiet, energy-efficient Carrier furnaces are designed to provide warmth to keep you cozy in winter and to circulate clean, refreshing air from your cooling system in the summer.

If you have a furnace not blowing hot air, there could be many things causing the problem, but one of the more common reasons your furnace may be blowing cold air is set to “on” instead of set to “auto”. Reset the thermostat to "auto" and the problems will disappear. If not, keep tracking the issue.

If the temperature in your home is cooler than expected, or if you hear your furnace start up and shut down quickly over and over, you might suspect a flame sensor has malfunctioned. If this is the case, you may also see an error message on your thermostat, or a flashing LED light on the furnace control board. A malfunctioning flame sensor could be causing your furnace to shut down. Because a functioning flame sensor and a malfunctioning flame sensor can both result in a furnace shutting down, it may be best to contact an expert to determine why your system isn’t functioning properly.
