Carrier 48XP042060300 Control Board
Your furnace or AC will not function without the control board in place and connected. The Carrier 48XP042060300 control board is constructed to command the gas valve, the igniter, the flame sensor and the blower all together. The chosen circuit board should have a replacement part number that matches both the brand and specific model of furnace or air handler you have. Be very careful while picking a new replacement board because of the diversity of certain brands.
What are the signs that the main board really needs to be replaced?
- There may be some sort of error code being displayed on the front of the control board
- The board needs to be reset repeatedly for it to work
- Air conditioner or furnace declines to run well
