International Comfort Products GPFM42K080F Ignition Control Board
The main reason to have an ignition control board is that it governs the natural gas, the ignition sequence as well as other safety devices. It is an important electronic safety board that, over the years, has merged to become a part of the main control board in order to have better control over the system.
Indications of a weak ignition control board
- Every other problem within the furnace is researched and comes to be acceptable
- The main ignition cycle refuses to fire up when it is supposed to
- The electrical signal from the primary thermostat gets lost before it makes it to the control board
