International Comfort Products C8MPN075B12A1 Control Board
The control board is designed to command the gas valve, the igniter, most sensors as well as the air circulator all in one unit. It is impossible for your furnace or air handler to even run at all lest the main control board is hooked up and is correctly configured. Be very careful while selecting a replacement because of the many variances of brands, models and types of systems. The board that you will choose should match both the brand and specific model of the unit you have installed.
Signals of an ineffective main board
- Entire unit does not initialize correctly
- System has some sort of error code showing up on the front of the control board
- The whole system needs to be reset repeatedly in order to continue running
