Carrier 38HDR024 Control Board
Your furnace or AC will not run lest this board is installed. The control board is constructed to direct the gas valve, the igniter, the flame sensor as well as the air circulator all together. The brand of board you choose will have a matching part number that will fit in the brand and the model of the system you have installed. Be very careful when you are deciding on a replacement due to the many differences between brands, models and types of systems.
Subtle cues of a barely functioning primary control board
- The AC or furnace ceases to initialize at all
- The entire system has to be reset repeatedly for the heating or cooling to kick in
- There is a numbered error code lit up somewhere on the board
