International Comfort Products T8MPL100F20A1 Ignition Control Board
The main reason to have an ignition control board is that it controls the natural gas, the ignition timing and a few other devices. It has always been a vital device that, in most cases, has become a vital part of the main control board instead of a separate board.
Major indications of an unhealthy chief ignition control board
- Initial ignition sequence can not commence even when called upon
- Every other problem in the system is researched and comes to be fine
- The on-signal from the home thermostat never reaches the main control board
