Carrier 48GS048090300 Control Board
The Carrier 48GS048090300 control board is made to control everything including the gas valve, the igniter, most sensors as well as the air circulator all in one unit. Your furnace or AC will not be able to function lest the circuit board is in its proper place and configured for your unit. The control board picked must have a matching part number consistent with both the make and model of the system you have installed. You must do some research while selecting a replacement due to the many differences between particular brands and their models.
Some clues your Carrier control board is dead
- AC or heating system is unable to function whatsoever
- There seems to be some sort of error code being shown somewhere on the board
- The control board has to be turned off and back on all the time for it to kick in
