Description
The York S1-025-41336-000 is an OEM auto-reset (A/R) limit switch engineered to protect York heating systems from unsafe operating temperatures. When supply air or heat exchanger temperatures exceed the set point, this limit switch automatically opens the circuit to shut down the burner — then resets itself once temperatures return to a safe level, restoring normal operation without manual intervention.
Key Features
- Auto-reset (A/R) design — automatically resets once temperature drops to safe level
- Opens at 145°F to interrupt burner operation and prevent overheating
- Closes at 105°F to restore normal system operation
- OEM York replacement part for precise fit and reliable performance
- Designed for use in York furnaces and heating equipment
How It Works
The limit switch continuously monitors temperature within the furnace or air handler. If temperatures rise to 145°F — indicating a potential overheat condition — the switch opens and interrupts the burner circuit. As the unit cools and temperature falls back to 105°F, the switch automatically closes and allows the system to resume normal operation. This auto-reset functionality reduces service calls and minimizes downtime.
