International Comfort Products H8MPL100F20A1 Ignition Control Board
The main ignition control board keeps an eye on the natural gas, the ignition timing and all the flame sensing devices. It has always been a vital circuit board that is usually a part of the main control board in order to have better control over the system.
Red flags of a dying main ignition board
- Any other device within the heating and AC system is inspected and turns out to be okay
- Heating and cooling system does not commence even though it is supposed to
- The electrical signal from the primary thermostat never turns up at the main control board
