Carrier 48JZ048090300 Control Board
The Carrier 48JZ048090300 control board is made to oversee the gas valve, the ignition igniter, most sensors as well as the blower all in one unit. It is impossible for your furnace or air handler to even operate whatsoever lest the circuit board is configured and seated properly. You should always be careful when you are deciding on a replacement due to variances between heating and cooling systems. The board you choose is supposed to have a part number that matches both the make and model of the unit you have installed.
Signals your main board should need replacing
- Your HVAC unit is unwilling to do anything correctly
- When turned on, there is some sort of code randomly appearing on the control board
- Power to the control board has to be turned off and back on quite frequently for it to work
