International Comfort Products T8MPN050B12A1 Control Board
The control board is designed to direct everything including the gas valve, the igniter, most sensors and the blower all at once. Most systems will not activate lest the main control board is in connected and operational. The selected board must be compatible with both the brand and model of your International Comfort Products T8MPN050B12A1 unit. You must be careful upon picking a replacement board due to the vast differences in certain brands.
Some clues of an inadequate main circuit board
- The AC or furnace declines to start correctly
- There seems to be some sort of error code revealed on the board
- Everything has to be powered down and back up quite frequently for the system to continue working
