Trane PTHD150 Flame Sensor
A flame sensor is a safety device that senses the acceptable flame upon ignition. For obvious reasons, if the sensor get triggered the whole HVAC system will remain stopped for as long as the problem remains.
Do you know if your safety flame sensor is almost dead?
- The entire heating system will kind of run occasionally when the time is right
- The gas entering the furnace has a tough time trying to begin an ignition sequence and closes down
- Your furnace is unwilling to begin operations and spits out an error code on the main board
