Carrier 38YD Control Board
The entire heating and cooling system will not run at all lest the circuit board is in place and connected. The control board is created to direct the gas valve, the igniter, most sensors as well as the air circulator all together. It is imperative that you select wisely when you choose a control board due to the many differences between models within certain brands. The board you select should match both the brand and specific model of the unit in question.
Clues your control board will need to be replaced
- The board has to be reset habitually in order to continue running
- The unit is not able to start well
- When turned on, there is numbered code randomly appearing on the board
