Carrier 38YSA036 Control Board
The Carrier 38YSA036 control board is constructed to regulate the gas valve, the igniter, most sensors and the blower all in one unit. It is impossible for your furnace or air handler to even operate lest the main control board is accurately installed and configured. A replacement board must have a matching part number consistent with both the brand and model of the system you have installed. You should always be careful upon choosing a board as a replacement due to the vast differences in HVAC systems.
What warnings should I watch out for to know if my control board is crapping out?
- The power to the system needs to be reset more often than not in order to run
- There is a strange code being shown on the control board
- The unit is unwilling to do anything correctly
