SPT TN-09E Ignition Control Board
The main ignition control board may control the main gas intake valve, the ignition timing and the flame sensing circuits. It has always been a vital electronic safety board that has now become a major component of the main board for safety reasons.
Signs to watch for in a failing ignition board
- The main ignition cycle can not launch when it is supposed to
- Any other device connected to the system is explored and ends up being in good health
- The initial signal from the home thermostat does not reach the main board
