Product Details

Description

Ensure the safety and efficiency of your heating system with this 3-inch high limit switch. Designed as a critical safety component for gas furnaces and HVAC units, the L200-30F high limit control monitors internal temperatures to prevent the heat exchanger from overheating. When temperatures reach the 200°F threshold, the switch opens to interrupt the heating cycle, protecting your appliance and home. This thermal cutout switch features an automatic reset, closing again once the temperature drops by 30°F. If your furnace is frequently cycling off or failing to ignite, replacing a faulty or worn limit control is an essential repair for maintaining consistent airflow and safe operation. Engineered for durability and reliable performance in residential and commercial forced-air systems.
