Description
The York S1-025-46401-000 is an OEM manual reset limit switch designed to protect furnace and heating systems from unsafe operating temperatures. When the system exceeds its designed temperature threshold, this limit switch opens the circuit and shuts down the heating operation — requiring a manual reset before the system can resume normal function. This built-in safety mechanism helps prevent equipment damage, heat exchanger failure, and potential hazards caused by overheating conditions.

Why Choose a Manual Reset Limit Switch?
Unlike automatic reset limit switches, a manual reset switch requires a technician to physically reset the device after a trip event. This ensures the root cause of the overheating condition is identified and corrected before the system is returned to service — adding an important layer of safety and accountability to your HVAC maintenance process.
