Carrier 38YKC036 Control Board
The control board is constructed to operate everything including the gas valve, the igniter, all the sensors as well as the air circulator all at once. HVAC systems will not function without the board installed as it should be according to the manufacturer. Be very careful when you are deciding on a replacement because of the diversity of systems. The board you select is supposed to have a part number that matches both the brand and specific model of the unit you have installed.
How can I tell if my control board is not working right?
- Power to the control board needs to be reset many times a week for everything to run again
- System has flashing code lit up on the control board
- The whole unit ceases to start period
