Description
The York S1-025-30265-700 is an OEM 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 set point, the switch opens the control circuit to shut down the burner — then automatically resets once temperatures return to a safe operating level, minimizing nuisance service calls.
Key Features
- Auto-reset operation — restores normal furnace function once safe temperatures are reached
- Temperature range: 150°F to 185°F operating limit
- OEM York replacement part — direct drop-in fit for compatible York furnace models
- Protects heat exchangers and internal components from thermal damage
- Reliable bimetal sensing element for consistent, repeatable trip performance
- Compact design for easy installation in tight furnace cavities
