Description
The York S1-024-35658-000 is an OEM replacement limit control designed to protect York heating systems from overheating and unsafe operating conditions. This limit control monitors supply-air or heat exchanger temperatures and automatically opens the circuit at 170°F to shut down the burner, then resets (closes) at 50°F once temperatures return to a safe level — providing reliable, automatic protection for the system and occupants.
Key Features
- OEM York replacement part — ensures proper fit and function
- Opens (trips) at 170°F to interrupt burner operation during overheat conditions
- Closes (resets) at 50°F differential for automatic system recovery
- Protects heat exchangers and downstream components from thermal damage
- Direct drop-in replacement for compatible York furnace and heating equipment models

Application
This limit control is a critical safety component in York furnaces and air handlers. When the system temperature exceeds the 170°F open setpoint — due to restricted airflow, a dirty filter, or a blower failure — the limit control opens the circuit, cutting off the burner to prevent damage or fire hazard. Always verify compatibility with your specific York model before installation.
