Whirlpool ATE0743CPP0 Control Board
The entire heating and cooling system will not activate without the control board configured and seated properly. The control board is made to command everything including the gas valve, the ignition igniter, most sensors and the blower all at once. Any control board you choose will have to be compatible with both the brand and specific model of the system you have installed. You must do some research when you are deciding on a replacement due to the many differences between heating and cooling systems.
Signals of an inadequate main board
- The system has to be reset frequently for it to work
- There may be an error code lit up on the circuit board
- The AC or furnace declines to operate period
