Carrier DR Control Board
It is impossible for your furnace or air handler to even be able to function unless this board is in place and connected. The control board is created to oversee everything including the gas valve, the igniter, all the sensors as well as the blower all together. The correct control board must have a matching part number consistent with both the make and model of the unit in question. It is of utmost importance while picking a new replacement board due to the vast differences in HVAC systems.
Some clues your main board is not going to last much longer
- Heat or AC unit is unwilling to go properly
- The entire system has to be reset frequently for it to kick in
- There is a type of code suddenly appearing somewhere on the circuit board
