Carrier 38QRR024 Control Board
The Carrier 38QRR024 control board is constructed to direct the gas valve, the igniter, all the sensors and the blower all at once. Your air handler will be unable to run at all lest the main control board is in connected and operational. Be absolutely sure when you are choosing a replacement board due to differences in heating and cooling systems. The control board you choose will have a part number that will match the brand and the model of your Carrier 38QRR024 unit.
Major warnings of an inadequate main board
- There may be some sort of code displayed on the circuit board
- The board has to be powered down and back up all the time for it to run
- AC or heating system is unwilling to work at all
