Carrier 38BYG048 Control Board
The Carrier 38BYG048 control board is made to direct the gas valve, the igniter, most sensors as well as the air circulator all in one unit. Most systems will not operate whatsoever unless this board is properly connected to the unit. It is of utmost importance when you are choosing a replacement board because of the wide variety of particular brands and their models. The board you select should match both the brand and model of your heating and cooling system.
Some clues your control board will not live much longer
- There seems to be a fault code directly somewhere on the circuit board
- Air conditioner or furnace cannot run well
- Everything has to be turned off and back on many times a day for the system to operate once again
