The DSI control board is the nerve center of the heating system — it sequences the inducer motor, spark igniter, gas valve, and flame verification circuit in precise timing. When the board fails, common symptoms include a complete no-heat condition, repeated ignition lockouts, failure to prove flame even when the burner lights, or erratic furnace cycling that no thermostat adjustment can resolve.
