Carrier 38YSA030 Control Board
Your furnace or AC will not run at all without this vital piece of hardware is properly connected to the unit. The Carrier 38YSA030 control board is created to operate the gas valve, the ignition igniter, the flame sensor as well as the blower all at once. Be very careful when you are deciding on a replacement due to so many small differences in HVAC systems. The board that you will choose should match both the brand and model of furnace or air handler you have.
Major symptoms your main board should be replaced
- Your HVAC unit cannot start properly
- Power to the circuit board needs to be reset often for the thermostat to kick in
- When turned on, there is a strange type of error code being shown on the circuit board
