Ensure your furnace operates safely and efficiently with this premium 7-inch high limit switch.

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.
