Product description

Specifically engineered for high-temperature safety, the Lennox H5891 Hi Limit Switch is a 60T15 series thermal protector with a 225-degree Fahrenheit trip point. This critical component is designed to monitor the most heat-sensitive areas of your Lennox heating appliance, providing an absolute fail-safe against excessive temperatures. If the internal heat reaches the 225F (L225F) threshold, the switch instantly opens its electrical circuit, shutting down the burner or heating element to prevent catastrophic damage or fire. This particular model is built with high-grade ceramic or heat-resistant plastic housings to ensure it remains functional even after years of proximity to the heat exchanger. Reliable high-limit protection is a requirement for all modern heating equipment, and this genuine Lennox part ensures your system remains compliant with original safety standards. It is an essential component for any technician or homeowner looking to restore the safe operation of a malfunctioning stove or furnace.
