Carrier 50JX Control Board
The system will cease to run at all lest this board is configured and seated properly. The control board is created to control the gas valve, the igniter, most sensors and the blower all in one unit. A replacement board should have part numbers that match both the make and model of the system you have installed. It is imperative that you select wisely when choosing a control board due to differences in brands, models and types of systems.
Easy warnings of a poorly working main board
- Could be an a flashing error code directly on the front of the control board
- The HVAC system needs to be reset quite a lot for the system to operate once again
- The furnace or AC does not start correctly
