Lennox 65W67 Pressure Switch

Lennox 65W67 Pressure Switch

Ensure your refrigeration or HVAC equipment operates within safe parameters with the Lennox 65W67 Pressure Switch. This high-side safety component is engineered to monitor discharge pressures and prevent compressor damage due to excessive head pressure. Rated as a 450/300 high pressure switch, it features a trip point at 450 PSI and a reset point at 300 PSI. Designed for professional field replacement, this manual reset pressure switch is a critical safeguard in Lennox high pressure control systems, maintaining the integrity of the refrigerant circuit by cutting power to the contactor if limits are exceeded.

Built for the rigors of commercial and industrial environments, the Lennox 65W67 is compatible with R-410A, R-22, and R-134a refrigerants. Its direct-mount design allows for seamless integration into high-pressure lines, providing an OEM Lennox replacement part that meets the exact specifications required by residential and commercial condensing units. For technicians diagnosing intermittent shutdowns or pressure-related lockouts, this 65W67 switch provides the precise calibration needed to maintain system efficiency and safety without the drift often found in universal alternatives.

Key Benefits
  • Precise Protection: Factory-calibrated 450 PSI cutout ensures immediate system shutdown during overpressure events.
  • Manual Reset Feature: Requires a technician to inspect the system before restarting, preventing repeated cycling under fault conditions.
  • Refrigerant Versatility: Fully compatible with R-410A, R-134a, and R-22 systems for broad application support.
  • Direct-Mount Design: Simplifies installation by threading directly onto the standard refrigeration access fitting or high-pressure port.
  • OEM Engineering: Guaranteed electrical and mechanical compatibility with legacy and modern Lennox equipment, replacing older part number 102447-01.
Common Questions

What causes a high pressure switch to trip in a Lennox system?
A trip at the 450 PSI threshold typically indicates restricted airflow across the condenser coil, a failed outdoor fan motor, or an overcharged system. This switch protects your compressor from these specific high-head pressure conditions.

Is the 65W67 an automatic or manual reset switch?
This is a manual reset switch. Once the pressure drops back below the 300 PSI reset point, a technician must physically press the reset button to restore the circuit, ensuring the underlying cause of the high pressure is addressed.

Can I use this switch for R-410A applications?
Yes, the Lennox 65W67 is rated for the higher operating pressures of R-410A, as well as lower pressure refrigerants like R-22, provided the system's safety limits align with the 450/300 PSI specifications.
