International Comfort Products NAC236GKA1 Ignition Control Board
The main ignition control board regulates the gas valve, the igniter and other important devices. It is an important electronic circuit board that, in most cases, has become a piece of the main circuit board instead of a separate board.
What warnings should I watch out for to know if my major ignition board is in need of replacing?
- The electrical signal from the primary thermostat does not turn up at the main control board
- Ignition system is unwilling to start even when the thermostat kicks it on
- Everything else within the furnace is inspected and seems to be a-OK
