Carrier 38ESA042 Control Board
The control board is constructed to command everything including the gas valve, the igniter, the flame sensor and the blower all together. HVAC systems will not be able to function lest the circuit board is hooked up and is correctly configured. A matching board will need to be a match with your existing board and be compatible with both the make and model of the system you have installed. You should always be careful when you choose a control board because of the many variances of brand and air handler types.
Important clues to watch for in a bad Carrier control board
- There may be some sort of error code shown on the control board
- System will not initialize at all
- The HVAC system has to be powered down and back up rather frequently for the system to continue working
