International Comfort Products HHP218AKA1 Ignition Control Board
The main ignition control board may control the natural gas, the igniter and some other sensors. It is an important safety feature that some companies have moved to be a vital part of the main control board instead of its own individual board.
Indications your main ignition board is in need of replacing
- The initial signal from the thermostat never does reach the control board
- Every other thing in the heating and cooling system is explored and ends up being a-OK
- HVAC ignition cycle fails to activate then the thermostat send a signal
