Lennox 11W50 Limit Control
The Lennox 11W50 Limit Control is a critical safety component designed for precise thermal regulation within Lennox residential and commercial furnaces. This high-limit switch features a fixed 170/140°F limit control setting, meaning it activates as a safety cutout if temperatures exceed 170°F and resets automatically when the exchanger cools to 140°F. As a direct replacement for Lennox part R46105-014 and 46105-014, this sensor is engineered for seamless integration into the factory wiring harness. This furnace high limit switch is a primary defense against heat exchanger overheating, ensuring the system operates within established safety parameters. Technicians frequently utilize the 11W50 limit switch to resolve frequent cycling issues or furnace lockout codes. Whether you are performing a seasonal tune-up or a critical repair, this OEM Lennox replacement part provides the specific resistive load and thermal response curve required by your heating equipment.
Key Benefits:
- Direct OEM Compatibility: Engineered as an exact functional equivalent to Lennox 11W50 and R46105-014, facilitating faster field installation.
- Precise Thermal Callibration: Specifically calibrated with 170 degree cut-out and 140 degree cut-in points to protect the heat exchanger and burner assembly.
- High-Temperature Durability: Constructed with industrial-grade materials to withstand the rigorous cycling and high-ambient heat of a furnace plenum.
- Standard UPC Tracking: Verified with UPC 66255133717 to ensure you are receiving the authenticated catalog component.
Common Questions:
How do I know if the Lennox 11W50 Limit Control is faulty?
If your furnace blower runs continuously despite no heat call, or if the unit shuts down prematurely before reaching the thermostat setpoint, the limit switch may have an open circuit or drifted out of calibration. Continuity tests using a multimeter across the terminals when cold should confirm if the switch is operational.
Can I use this as a replacement for other temperature ratings?
No. You must match the 170/140°F rating exactly. Installing a limit with a higher cutoff can lead to heat exchanger damage, while a lower cutoff will result in nuisance tripping and insufficient heating.
Is this switch an automatic or manual reset?
The 11W50 is an automatic reset limit switch, designed to re-engage the circuit once the system temperature drops below the 140°F threshold.
