International Comfort Products NTVM125KNA1 Ignition Control Board
An ignition control board controls gas intake, the igniter and some other sensors. The ignition control board was always an important circuit board that is usually a vital part of the main control board instead of a separate board.
Signs of an ineffective ignition control board
- HVAC ignition cycle can not begin no matter what
- Every other device within the furnace checked out to be a-OK
- Signal from primary thermostat never makes it to the main board
