Description
The York S1-025-53181-000 is an OEM auto-reset limit switch engineered to protect York furnaces and heating systems from dangerous overtemperature conditions. When supply-air or heat exchanger temperatures climb to the 180°F trip point, the switch opens the burner circuit to prevent equipment damage and potential hazards. Once temperatures fall back to the 140°F reset point, the switch automatically restores normal operation — eliminating the need for manual intervention and reducing service calls.
How It Works
The limit switch continuously monitors operating temperatures within the heating system. Its bimetal sensing element responds quickly and reliably to temperature changes, interrupting the control circuit at the set trip temperature and re-closing when safe operating temperatures are restored. The auto-reset design makes it ideal for residential and light-commercial furnace applications where nuisance shutdowns must be minimized.
