Sanyo C0971 Control Board
The control board is created to oversee everything including the gas valve, the ignition igniter, the flame sensor as well as the blower all at once. Most systems will not run lest the circuit board is correctly installed. You must be sure while picking a new replacement board because of the wide variety of particular brands and their models. Any control board you choose must have a matching part number consistent with both the brand and model of furnace or air handler you have.
What symptoms are present when the control board has a need to be replaced?
- There seems to be some sort of error code lit up on the circuit board
- The control board has to be turned off and back on a lot for it to run correctly
- The furnace or AC is unable to do anything properly
