Carrier 38EZA042 Control Board
The system will cease to be able to function unless the control board is hooked up and is correctly configured. The control board is constructed to control the gas valve, the igniter, all the various sensors as well as the air circulator all in one unit. You must be careful when choosing a control board due to differences in brands, models and types of systems. The proper control board should match the model number with both the make and model of HVAC system.
Major symptoms of a bad main board
- The HVAC system has to be powered down and back up repeatedly in order to run
- The AC or furnace will not start correctly
- System has a certain error code instantly appearing somewhere on the circuit board
