York S1-025-51476-000 Limit Switch
The York S1-025-51476-000 Limit Switch is a critical safety component engineered for HVAC system protection and precise temperature monitoring. This 120/150 Auto Limit Switch is a genuine OEM replacement part, functioning as a primary high-limit safety to prevent the furnace heat exchanger from reaching unsafe operating temperatures. With an automatic reset configuration, this SPST (Single-Pole Single-Throw) switch is designed to interrupt the burner circuit when the internal plenum temperature rises to its specific threshold and restore operation once the air has sufficiently cooled. This furnace high limit switch is built for durability in residential and light commercial York furnace applications, ensuring reliable performance and system longevity by mitigating risks associated with restricted airflow or blower failure. Utilizing an OEM HVAC part like the S1-025-51476-000 ensures exact terminal spacing and mounting alignment for a straightforward HVAC repair and optimal safety compliance.
Key Benefits
- Automatic Reset Functionality: Automatically restores the circuit once the system cools to safe parameters, reducing manual intervention for standard temperature fluctuations.
- Precision Thermal Monitoring: Designed with a 120/150-degree threshold to safeguard the heat exchanger from thermal stress and potential cracks.
- Broad Compatibility: Engineered as a direct York replacement part for a wide range of residential furnaces and air handlers.
- Enhanced System Safety: Acts as a failsafe to shut down gas valves or heating elements if the blower motor fails or air filters become severely clogged.
Common Questions
Is the S1-025-51476-000 an auto or manual reset switch?
This specific model is an automatic reset limit switch, meaning it will reset itself once the temperature drops below the lower set point (120°F), unlike rollout switches which typically require a manual button press.
What causes this limit switch to trip frequently?
Frequent tripping usually indicates airflow issues, such as a dirty furnace filter, blocked return ducts, or a failing blower motor, causing the heat exchanger to overheat.
Can I use this switch in non-York equipment?
While technically a limit control, it is highly recommended to use this OEM York part only in compatible Johnson Controls or York equipment to ensure the mounting depth and temperature settings remain within the original manufacturer's specifications.
