International Comfort Products T9MPD125L20B1 Ignition Control Board
The main reason to have an ignition control board is that it checks out the main gas intake valve, the igniter and some other sensors. It has always been a vital safety feature that some companies have moved to be a vital part of the main control board instead of having two separate boards.
How do you know when your chief ignition control board needs replacing?
- Heating and cooling system refuses to initiate even though it is supposed to
- Any other problem in the heating and cooling system checked out to be okay
- The on-signal from the main thermostat never turns up at the International Comfort Products control board
