Carrier 38BRC048 Control Board
Most systems will not activate without the main control board in its proper place and configured for your unit. The control board is constructed to operate the gas valve, the igniter, most sensors and the blower all together. The board you select will need to be a match with your existing board and be compatible with both the brand and model of HVAC system. Be absolutely sure when choosing a control board because of the many variances of brand and air handler types.
Signs your main board is dying
- The whole unit ceases to initialize whatsoever
- The whole system needs to be reset habitually in order to operate
- There may be an error code directly on the circuit board
