Carrier 48GP048130300 Control Board
The system will cease to function lest the main control board is in connected and operational. The control board is constructed to direct everything including the gas valve, the igniter, most sensors and the blower all in one unit. Be very careful upon picking a replacement board because of the wide variety of brand and air handler types. The control board picked will have to match part numbers both the brand and model of the unit you have installed.
Subtle cues of a poorly performing primary control board
- There is flashing code showing up on the board
- Heat or AC unit declines to go at all
- The whole system has to be reset repeatedly in order to operate
