Description
The York S1-025-38737-000 is an automatic-reset high-limit switch engineered to protect York furnaces and heating systems from dangerous overheating conditions. When supply-air or heat exchanger temperatures exceed the upper threshold, the switch opens the control circuit and shuts down the burner — then automatically resets once temperatures return to a safe level, minimizing nuisance service calls and keeping your system running efficiently.

- Open (trip) temperature: 160°F
- Close (reset) temperature: 140°F
- Genuine York OEM replacement part for precise fit and reliable performance
