Product Details

Description

Ensure your home heating system operates safely and efficiently with this professional-grade 3-inch high limit control switch. As a vital safety component in residential furnaces and HVAC units, this thermal limit switch monitors internal temperatures to prevent the system from overheating. This specific limit control is designed to automatically break the electrical circuit when the temperature reaches its 210-degree Fahrenheit threshold, protecting your heat exchanger and sensitive internal components from heat damage. The switch features a 30-degree differential, allowing the system to reset once the temperature drops to a safe operating level. Whether you are performing routine furnace maintenance or repairing a heating system that is short-cycling, this high-limit cutout is an essential replacement part for maintaining a secure and reliable climate control system.
