Royal Sovereign ARP-9411 Control Board
The control board is constructed to regulate everything including the gas valve, the ignition igniter, all the various sensors and the blower all together. The system will cease to run unless the control board is installed as it should be according to the manufacturer. A matching board should have a replacement part number that matches both the brand and model of the unit you have installed. Be very careful when choosing a control board due to the many differences between particular brands and their models.
What are some hints that my main circuit board is crapping out?
- The furnace or AC is not able to start well
- There seems to be a strange code indicated directly on the board
- The system has to be turned off and back on rather frequently for the furnace or AC to kick on
