Trane PTHD150 Control Board
The system will cease to run at all unless this board is installed. The Trane PTHD150 control board is created to command everything including the gas valve, the ignition igniter, most sensors and the blower all together. You must be careful while selecting a replacement due to the many differences between models within certain brands. The selected board will have a matching part number that will fit in both the brand and model of HVAC system.
Some clues of a weakening main circuit board
- The heating and cooling system refuses to do anything whatsoever
- The system board has to be turned off and back on all the time for it to run
- System has a strange code showing up on the circuit board
