International Comfort Products T8MPL100F20B1 Ignition Control Board
The main ignition control board checks the gas valve, the ignition timing and some other sensors. It is an important electronic safety board that some manufacturers have decided to blend to be a standard part of the main board in order to have better control over the system.
Signals of a poorly working main ignition board
- The initial signal from the primary thermostat never gets to the main control board
- HVAC ignition cycle declines to fire up when called upon
- Any other potential problem within the heating and AC system is explored and ends up being okay
