This premium Disc Limit Switch is a critical safety component designed for residential heating systems, including gas furnaces and air handling units. Functioning as a high limit control, this thermal switch monitors internal temperatures to protect your HVAC equipment from overheating. The L115-20F features an automatic reset mechanism that triggers when the temperature reaches its 115°F limit, cutting power to the heating circuit, and automatically reconnecting once the system cools down by 20°F. Replacing a worn or malfunctioning limit sensor can resolve common furnace issues such as short-cycling or system failure, ensuring your heating system operates efficiently and safely throughout the winter.
