The gas valve is the heart of your furnace's fuel delivery system — it receives a 24V signal from the control board and opens to allow precisely metered natural gas flow to the burners. A failed gas valve typically produces a no-heat condition, repeated ignition lockout faults, or a furnace that lights briefly then shuts down.
