Goodman GPH1348H21A Control Board
The control board is made to control the gas valve, the igniter, all the various sensors as well as the blower all at once. Your air handler will be unable to operate lest this board is hooked up and is correctly configured. You must be sure while selecting a replacement because of the wide variety of brand and air handler types. The selected board will have a part number that will match both the make and model of the unit you have installed.
Subtle hints your control board is on its last leg
- The control board has to be turned off and back on quite frequently for it to run
- When turned on, there is some sort of error code appearing on the board
- Air conditioning or heating system declines to function well
