Description
The York S1-02532706000 Limit Switch/Thermostat Opens at 150°F and Closes at 120°F operates as a temperature-sensitive safety part that interrupts electrical circuits when internal heat reaches threshold levels. It operates through a bimetal sensing element that expands at 150°F to open the circuit and resets at 120°F during the cooling cycle, restoring continuity. In HVAC systems furnace and air handler assemblies, it is positioned near the heat exchanger area to respond to excessive climatic rise. The component reduces overheating, maintains thermal limits within equipment, and ensures stable cycling during heating operation across repeated temperature fluctuations.
