International Comfort Products CAC448GKA1 Ignition Control Board
An ignition control board may control gas flow, the ignition ignitor and some more sensing equipment. The ignition control board was always an important circuit board that some manufacturers have decided to blend to be a part of the main control board for safety reasons.
Key symptoms of a barely functioning major ignition board
- Everything else in the heating and cooling system checks out fine
- Heating and cooling system does not start when it receives a proper signal
- The on-signal from the main thermostat never makes contact with the control board
