SPT WA-1220H Ignition Control Board
An ignition control board keeps an eye on the gas valve, the ignition timing and some other sensors. It has always been a vital circuit board that some manufacturers have decided to blend to be a major component of the main board for safety reasons.
What happens when my SPT ignition control board really needs to be replaced?
- Heating and cooling system refuses to fire up even though it is supposed to
- The electrical signal from the home thermostat does not make it to the main board
- Every other thing within the system is researched and comes to be all right
