Carrier 38BK Control Board
Your system definitely will not run unless this important circuit board is accurately installed and configured. The Carrier 38BK control board is made to oversee the gas valve, the ignition igniter, the flame sensor as well as the blower all together. It is of utmost importance upon choosing a board as a replacement due to so many small differences in heating and cooling systems. The control board picked is supposed to have a part number that matches both the brand and specific model of HVAC system.
Key signs of a failing main board
- Everything has to be powered down and back up a lot for the heating or cooling to kick in
- The furnace or AC declines to work whatsoever
- There is a strange code instantly appearing on the control board
