Carrier 50JZ024310 Flame Sensor
A flame sensor can only be found on furnaces that burn a gas. It is a safety sensor that senses the acceptable flame during ignition. For obvious reasons, when the flame sensor gets triggered by something the entire HVAC system will stop until the problem is repaired.
Major symptoms of a barely functioning safety flame sensor
- The whole system will sometimes work on certain occasions when it wants to
- The furnace cannot produce heat when the control board tells it to
- The gas entering the furnace will not begin an ignition sequence and closes down
