Carrier 48GX042090300 Control Board
Your air handler will be unable to function unless this important circuit board is accurately installed and configured. The control board is constructed to oversee everything including the gas valve, the igniter, all the various sensors and the blower all in one unit. The brand of board you choose should match both the brand and specific model of air handler system you have. Be absolutely sure when you are deciding on a replacement due to variances between brand and air handler types.
What signals that my Carrier control board is on its last leg?
- When turned on, there is some sort of error code revealed on the front of the control board
- AC or heating system cannot go at all
- The control board has to be turned off and back on quite a lot for the furnace or AC to kick on
