Carrier 38TSA042 Flame Sensor
The flame sensor is one of the safety features that senses the acceptable flame during ignition. Due to safety concerns, when the flame sensor is activated the system will halt until the problem is remedied and the system is reset.
Cues of a barely functioning Carrier flame sensor
- LP or natural gas cannot begin an ignition sequence and some type of error flashes on the main board
- The entire heating system kicks in rarely but only on the third Wednesday of on months beginning on Thursday
- Your gas furnace is unwilling to even start when the thermostat kicks in
