Carrier FF1DNE018075AAAA Control Board
The entire heating and cooling system will not function lest the main control board is accurately installed and configured. The control board is designed to operate everything including the gas valve, the igniter, all the various sensors and the blower all together. Be very careful upon choosing a board as a replacement due to the many differences between brands, models and types of systems. The brand of board you choose must be compatible with both the brand and specific model of your particular system.
Subtle hints your main board is failing
- The system board has to be powered down and back up repeatedly for the heating or cooling to kick in
- The AC or furnace declines to do anything well
- Could be an numbered code revealed somewhere on the circuit board
