Description
The York S1-025-41322-000 is a factory-authorized OEM automatic-reset limit switch engineered to protect York heating systems from unsafe operating temperatures. Designed as a direct replacement component, this limit switch monitors heat exchanger temperatures and automatically interrupts the burner circuit when temperatures exceed the rated threshold — then resets automatically once safe operating conditions are restored.
How It Works
The limit switch continuously monitors the temperature within the furnace plenum or heat exchanger. If the temperature climbs above the upper set point, the switch opens the control circuit, shutting down the burner to prevent overheating damage. Once temperatures fall back within the safe operating range, the auto-reset function restores normal operation without requiring manual intervention.
