International Comfort Products PHAD24N1K1 Control Board
Your air handler will be unable to operate whatsoever lest the circuit board is accurately installed and configured. The International Comfort Products PHAD24N1K1 control board is made to regulate everything including the gas valve, the igniter, all the various sensors as well as the air circulator all at once. Any control board you choose is supposed to have a part number that matches both the brand and model of the unit you have installed. You should always be careful while searching to pick up a replacement control board due to the many differences between brand and air handler types.
Important clues of a faulty primary control board
- The board has to be reset rather frequently in order to run
- The furnace or AC refuses to do anything whatsoever
- When turned on, there is lit up error code instantly appearing on the board
