International Comfort Products CHP424AKA1 Control Board
The International Comfort Products CHP424AKA1 control board is made to regulate everything including the gas valve, the igniter, the flame sensor as well as the air circulator all together. Your air handler will be unable to activate without this vital piece of hardware is accurately installed and configured. Be very careful while choosing a new control board due to so many small differences in certain brands. The selected board should match both the brand and specific model of the system you have installed.
Some clues of an ineffective main board
- The entire system has to be turned off and back on habitually for the heating or cooling to kick in
- Entire unit cannot go at all
- There is a strange code indicated somewhere on the board
