Carrier 38QR Control Board
The HVAC system will be unable to function without the main control board in place and connected. The control board is made to direct the gas valve, the igniter, the flame sensor as well as the blower all in one unit. A replacement board is supposed to have a part number that matches both the make and model of air handler system you have. You must be sure when you are choosing a replacement board due to differences in HVAC systems.
Easy warnings of a poorly working Carrier control board
- There is flashing code instantly appearing on the control board
- Air conditioning or heating system is unable to work properly
- The system has to be turned off and back on all the time for it to run
