Carrier 38TXA024 Control Board
The Carrier 38TXA024 control board is constructed to direct the gas valve, the ignition igniter, all the sensors as well as the blower all in one unit. Heating and cooling systems will not even be able to function without this vital piece of hardware is configured and seated properly. You must do some research when you are choosing a replacement board due to the many differences between brand and air handler types. A control board that you have chosen is supposed to have a part number that matches the brand and the model of your heating and cooling system.
Hints your control board is not going to last much longer
- Power to the circuit board has to be turned off and back on quite frequently for everything to run again
- There is flashing code suddenly appearing somewhere on the board
- AC or heating system declines to do anything properly
