Carrier 25HPA448A0030010 Control Board
HVAC systems will not run at all without the main control board installed as it should be according to the manufacturer. The control board is constructed to oversee everything including the gas valve, the igniter, most sensors as well as the blower all at once. Be very careful while searching to pick up a replacement control board due to the many differences between certain brands. The correct control board should match the model number with both the make and model of your Carrier 25HPA448A0030010 unit.
Warnings your main board is going to die
- The control board has to be powered down and back up frequently for it to run correctly
- Air conditioner or furnace does not go whatsoever
- There may be a flashing error code lit up somewhere on the circuit board
