Trane PTHD090 Flame Sensor
A flame sensor is an important feature that will dependably sense the exact flame upon ignition. Due to the overall safety issue, if the flame sensor is triggered everything comes to a halt until the problem is dealt with.
Major symptoms your flame sensor is dying
- The heat system cannot ramp up and produces an error code on the circuit board
- The whole system works sporadically only
- The type of gas you use finds it impossible to burn and the board throws an error
