International Comfort Products HAC048AKA1 Control Board
The control board is designed to regulate the gas valve, the igniter, all the sensors and the blower all in one unit. Your system definitely will not operate whatsoever without the main control board properly connected to the unit. A replacement board will have a part number that will match both the brand and specific model of air handler system you have. You must do some research while selecting a replacement due to variances between systems.
What are some indications that my main circuit board is almost going bad?
- There is some sort of error code instantly appearing on the front of the control board
- The HVAC system has to be reset quite frequently for everything to run again
- Entire unit is not able to function whatsoever
