Carrier 48GS042090300 Control Board
The system will cease to activate without the board properly connected to the unit. The Carrier 48GS042090300 control board is constructed to operate everything including the gas valve, the ignition igniter, most sensors as well as the blower all in one unit. Be very careful while picking a new replacement board due to so many small differences in HVAC systems. The proper control board will need to be a match with your existing board and be compatible with both the make and model of your heating and cooling system.
Symptoms of an unhealthy main circuit board
- System has an error code indicated somewhere on the board
- The heating and cooling system ceases to run at all
- The entire system has to be reset quite frequently for it to run
