SPT WA-1420H Ignition Control Board
The main ignition control board may control the main gas intake valve, the ignition sequence as well as other safety devices. The ignition control board was always an important board that, in most cases, has become a piece of the main circuit board instead of its own individual board.
Clues the chief ignition control board is failing
- The ignition system is unable to begin even when called upon
- The initial signal from the main thermostat never makes contact with the control board
- Every other thing in the heating and cooling system checks out in good condition
