Description
The York S1-02541320000 Auto Reset Limit Switch Thermostat is a temperature control component used in heating equipment to monitor airflow and internal system heat levels. It operates by opening the circuit at 140F and automatically closing again at 100F, supporting regulation of safe operating temperatures during furnace operation. It is installed in residential and light commercial furnaces and air handling systems where overheating protection is required. Within the system, it serves as a safety cutoff that prevents excessive heat buildup, protects the heat and blower assembly, and maintains operating conditions.
