Carrier 38TXA036 Control Board
Your system definitely will not activate without this vital piece of hardware is installed. The Carrier 38TXA036 control board is made to command the gas valve, the igniter, all the various sensors as well as the air circulator all together. A control board that you have chosen is supposed to have a part number that matches both the brand and model of the unit you have installed. Be very careful upon picking a replacement board due to differences in models and types.
Clues of a poorly performing main board
- System has a type of code appearing on the circuit board
- The entire system has to be powered down and back up habitually for it to run
- The AC or furnace does not go period
