The York S1-025-29041-006 is an OEM auto-reset limit switch engineered to provide precise high-temperature protection in York furnace and heating systems. Designed with a 3-inch insert-style mounting, this limit switch installs directly into the heat exchanger or plenum assembly for accurate air-temperature sensing right at the source.
How It Works
This automatic limit switch monitors supply-air or heat exchanger temperatures and opens the burner circuit when temperatures exceed the upper set point, preventing overheating and protecting the heat exchanger from thermal damage. Once temperatures return to a safe level, the switch automatically resets — eliminating the need for manual intervention during normal operation.
Key Features
- OEM York replacement part — ensures proper fit and function
- Auto-reset operation — automatically restores normal system operation once safe temperatures are reached
- Temperature range: 170°F to 200°F — opens on temperature rise to protect equipment
