Carrier 50XZ036300 Control Board
The control board is made to direct everything including the gas valve, the igniter, all the sensors as well as the air circulator all at once. Your furnace or AC will not activate without the control board in its proper place and configured for your unit. The proper control board should match the brand and the model of the unit in question. Be very careful when choosing a control board due to the many differences between brand and air handler types.
Signals your main board needs to be replaced
- The entire system is not able to go correctly
- When turned on, there is a certain error code appearing on the control board
- The system board has to be reset more often than not in order to run
