Product Details

Description

Ensure your heating system operates safely and efficiently with this premium 7-inch high limit control switch. Designed as a critical safety component for residential and commercial HVAC units, this thermal cutout switch monitors internal temperatures to prevent dangerous overheating. If the heat exchanger or plenum temperature exceeds the safety threshold, this switch automatically interrupts the heating circuit, protecting your equipment from structural damage and ensuring safe operation. Featuring a standard 120-degree Fahrenheit cutout and a 30-degree differential, it provides reliable performance for furnaces experiencing cycling issues or thermal failures. This part is a vital replacement for maintaining the longevity and safety of your forced-air heating system.
