York S1-025-47297-000 Control

The York S1-025-47297-000 Control is a critical safety and operational component designed for high-efficiency York HVAC systems. As a 95 CLS 135 OP TEMP CNTRL, this automatic reset limit switch is engineered to monitor heat exchanger temperatures, specifically calibrated for units with a 95,000 BTU capacity. When the 135°F operating temperature threshold is reached, the York S1-025-47297-000 opens the circuit to prevent overheating, automatically resetting once temperatures return to safe parameters. This genuine OEM York part ensure electrical compatibility and mounting alignment without the field modifications often required by "universal" replacements. Integrating this furnace limit control into your York furnace maintenance routine prevents nuisance tripping and protects the heat exchanger from thermal stress, maintaining the specific airflow and combustion requirements of 95K BTU heating units.

Key Benefits:

• Precision Thermal Monitoring: Factory-calibrated to 135°F to ensure exact high-limit protection for Johnson Controls and York equipment.
• OEM Engineering: Direct replacement for S1-025-47297-000, ensuring the correct footprint and terminal orientation for rapid HVAC contractor installation.
• Auto-Reset Functionality: Eliminates manual intervention for temporary thermal spikes while maintaining a strict safety envelope.
• System Optimization: Designed specifically for 95K BTU furnace configurations to prevent short-cycling and uneven heat distribution.
• Reliable Heat Management: Constructed with high-grade bimetal sensors to withstand the demanding duty cycles of residential and light commercial HVAC applications.

Common Questions:

What causes a 135°F limit switch like the S1-025-47297-000 to trip?
Usually, a trip is caused by restricted airflow. Check for a clogged furnace air filter, blocked return ducts, or a failing blower motor that isn't pulling enough CFM across the heat exchanger.

Can I replace this with a higher temperature limit switch?
No. The York S1-025-47297-000 is rated specifically for 135°F based on the UL testing of the furnace. Installing a higher limit can lead to heat exchanger failure or fire hazards.

Is this control compatible with other brands?
While York is the primary manufacturer, this part is frequently used in Luxaire and Coleman equipment. Always verify the part number on your existing roll-out or limit switch before installation.
