Carrier CPHEATER052A00 Control Board
The control board is designed to regulate the gas valve, the ignition igniter, all the various sensors and the blower all together. Most systems will not function unless the control board is installed as it should be according to the manufacturer. Be absolutely sure when you are choosing a replacement board because of the wide variety of brand and air handler types. The board you select will need to be a match with your existing board and be compatible with the brand and the model of air handler system you have.
What are some indications that my primary control board is failing?
- The whole system has to be powered down and back up rather frequently for the furnace or AC to kick on
- Could be an a fault code randomly appearing on the control board
- The heating and cooling system ceases to go correctly
