Carrier 38CKC048 Control Board
Your furnace or AC will not run at all lest this board is accurately installed and configured. The Carrier 38CKC048 control board is made to command everything including the gas valve, the igniter, most sensors and the blower all at once. You must do some research while searching to pick up a replacement control board due to the vast differences in models and types. The proper control board will have a matching part number that will fit in both the brand and specific model of the unit in question.
Important hints your main board needs replacing ASAP
- System has a certain error code displayed somewhere on the circuit board
- Power to the circuit board has to be turned off and back on quite often in order to continue running
- Air conditioning or heating system does not initialize correctly
