International Comfort Products HHP430GKA1 Ignition Control Board
The main reason to have an ignition control board is that it checks the gas valve, the ignition timing and some other sensors. The ignition control board was always an important safety device that, over the years, has merged to become a part of the main control board instead of having two separate boards.
Cues of a poorly performing main ignition board
- The electrical signal from the home thermostat never makes it to the main control board
- HVAC ignition cycle can not fire up at all
- Any other potential problem within the heating and AC system is inspected and seems to be just fine
