International Comfort Products HAC242AKA1 Control Board
HVAC systems will not run at all lest the circuit board is installed. The control board is created to oversee the gas valve, the ignition igniter, all the various sensors as well as the air circulator all at once. Be very careful when you choose a control board because of the many variances of particular brands and their models. A replacement board should match both the brand and specific model of HVAC system.
Key clues to watch for in a failing main circuit board
- AC unit or heating unit does not operate well
- The power to the system has to be turned off and back on repeatedly for it to work
- When turned on, there is numbered code showing up on the board
