Description
The York S1-02537344000 3″ Insert Auto Reset Limit Switch Thermostat is a temperature-control safety component used to monitor heat levels inside heating equipment. It operates with a 215F open point and a 185F close point, automatically resetting when temperatures return to the normal range. It is applied in HVAC systems within furnace and air-handling assemblies to prevent overheating by cycling system operation based on temperature changes. The switch is installed in the heat path or an air flow section where it detects rising temperature and signals the control circuit to interrupt or restore operation, supporting safe and stable heating performance.
