Carrier 38CKC042 Control Board
Heating and cooling systems will not even run without this vital piece of hardware is installed. The control board is designed to direct the gas valve, the igniter, most sensors as well as the air circulator all together. A matching board should have a replacement part number that matches both the brand and specific model of your particular system. You must be sure when you choose a control board due to the many differences between particular brands and their models.
Red flags of an unhealthy main board
- AC unit or heating unit will not work well
