Carrier 58MSA10012120 Control Board
Your system definitely will not run at all without the main control board accurately installed and configured. The Carrier 58MSA10012120 control board is constructed to control everything including the gas valve, the igniter, the flame sensor as well as the air circulator all at once. Any control board you choose will have a matching part number that will fit in the brand and the model of your particular system. You should always be careful when you choose a replacement due to the many differences between brand and air handler types.
Major clues your primary control board needs replacing
- The entire system has to be turned off and back on more often than not for the heating or cooling to kick in
- Could be an error code being displayed on the front of the control board
- Entire unit refuses to start whatsoever
