Description
The York S1-3L01-230 Hi Limit Thermostat/Fan Control Snap Disc L230-40F is a temperature activated control equipment used to regulate furnace operation and blower cycling. It monitors air temperature inside heating equipment and responds when preset thermal thresholds are reached, supporting the management of fan start and stop operations during heating cycles. This component is commonly installed in residential and commercial forced air furnaces where controlled airflow and temperature supervision are required. Within the system, it interfaces with the control circuit to support proper heat distribution and operational sequencing of the blower assembly.
