Carrier 38AK Control Board
The Carrier 38AK control board is designed to oversee the gas valve, the igniter, all the various sensors as well as the air circulator all at once. It is impossible for your furnace or air handler to even operate whatsoever without the main control board in connected and operational. The board that you will choose will have to be compatible with the brand and the model of your Carrier 38AK unit. You must do some research when you choose a control board due to differences in models within certain brands.
Some clues your Carrier control board will have to be replaced
- The AC or furnace refuses to function correctly
- Could be an lit up error code showing up on the board
- The board has to be turned off and back on rather frequently for everything to run again
