SPT WA-1000E Ignition Control Board
The purpose of the ignition control board is that it may control gas flow, the igniter and some other sensors. The ignition control board was always an important electronic circuit board that some companies have moved to be a major component of the main board for enhanced safety.
Key symptoms of a worsening main ignition board
- The initial signal from the home thermostat does not make it to the control board
- Ignition sequence declines to kick in even when called upon
- Any other problem throughout the system checks out fine
