Product Details

Description

Ensure the safety and efficiency of your heating system with this professional-grade 3-inch high limit switch. Designed as a critical safety component for furnaces and HVAC units, this temperature limit control acts as a thermal cutout to prevent overheating. The switch is engineered to automatically interrupt the electrical circuit if the internal temperature exceeds safe operating parameters, specifically tripping at 250°F and resetting after a 30°F cooling period. This reliable replacement part is essential for maintaining optimal airflow and protecting your appliance from heat-related damage. Whether you are performing routine maintenance or a critical repair, this high-limit sensor provides the precision and durability needed for consistent climate control performance.
