Product Details

Description

Ensure your furnace operates safely and efficiently with this premium 7-inch high limit switch. Designed as a critical safety component for residential heating systems, this limit control switch monitors the internal air temperature of your furnace or air handler. It is engineered to automatically interrupt the heating cycle if temperatures exceed the safe operating threshold of 175°F, preventing overheating and protecting your HVAC equipment from potential damage. This thermal cutout switch features a 30-degree differential, allowing the system to reset and resume operation once it has cooled to a safe level. This is an essential replacement part for malfunctioning or 'tripped' safety switches, helping to maintain consistent indoor comfort while providing a vital layer of protection for your home's heating system.
