Air controls (venturi knobs) do not introduce air; jets feel flat with no bubbles even when air valves are open.

Safety: Turn off power before removing air control components.

• Check air valves: Turn the air control knobs fully open and closed. If they are stiff or spin freely without effect, the internal valve may be broken.
• Inspect air intakes: Locate the air intake openings under the cabinet and ensure they are not blocked by insulation or debris.
• Replace air control: If the valve body is cracked or stuck, replace the air control assembly with a Saratoga-compatible part.
