Trane PTHD120 Ignition Control Board
An ignition control board oversees gas intake, the ignition timing and some other sensors. It has always been a vital electronic circuit board that, over the years, has merged to become a major component of the main board in order to have better control over the system.
What are some hints that my Trane ignition control board is not working right?
- Every other potential issue in the heating and cooling system is looked at and turns out to be problem-free
- The electrical signal from the home thermostat does not reach the main control board
- Initial ignition sequence does not initiate even when the thermostat kicks it on
