2. Flame Sensor

The flame sensor is one of the most important safety features on a furnace. If the furnace is blowing cold air, it could be because the flame sensor is dirty or malfunctioning. The flame sensor is a small rod that sits in the fire chamber and detects whether there is a flame present. If the sensor is dirty, it may not be able to detect the flame, and the furnace will shut off. To clean the sensor, simply remove it and wipe it with a cloth. If the sensor is malfunctioning, it will need to be replaced.
