International Comfort Products HAC024AKA1 Flame Sensor
A flame sensor can only be found on furnaces that burn a gas. It is a safety sensor that senses the flame while the system is starting. As with most devices used for safety reason, when the sensor is triggered by an event the furnace will not start until the problem is repaired.
What are the clues to watch out for to know my primary flame sensor is about to stop working?
- The unit turns on occasionally when the time is right
- The furnace is unable to even begin to start when you want it to
- The main type of gas refuses to try to burn and the control shows an error
