This mechanical damper thermostat knob is designed to regulate airflow into a wood-burning furnace by adjusting the intake on the feed door. Using a bi-metal mechanism, it responds to temperature changes to help control combustion and maintain steady heat output. Replacing a worn or damaged air control restores proper airflow management, improves heating efficiency, and helps ensure consistent, reliable performance during normal furnace operation.
