{"product_id":"762-077","title":"762-077","description":"This 3\/4\" automatic reset disc limit switch is a vital safety component for residential HVAC systems and gas furnaces. As a high-limit control, it monitors air temperature and automatically breaks the electrical circuit if the system exceeds safe operating limits, specifically triggering at 135°F. This prevents overheating and potential damage to your heating equipment. Designed with an automatic reset feature, the switch restores connectivity once the temperature drops by 40°F, ensuring your furnace or heater returns to normal operation without manual intervention.
