Carrier 38YRA024 Control Board
The system will cease to operate unless this important circuit board is accurately installed and configured. The Carrier 38YRA024 control board is constructed to command the gas valve, the igniter, all the sensors as well as the air circulator all together. You must be careful when you choose a replacement due to so many small differences in particular brands and their models. The control board picked should have a replacement part number that matches both the make and model of air handler system you have.
Some clues poorly running control board
- Air conditioning or heating system refuses to function at all
- When turned on, there is some sort of error code shown directly somewhere on the board
- The system board has to be powered down and back up all the time for the thermostat to kick in
