Lennox 59W33 Pressure Switch
The Lennox 59W33 Pressure Switch (OEM Part # 102310-01) is a critical safety component designed for precise monitoring of combustion blower performance and venting integrity. As a low pressure switch, it is factory-calibrated to actuate at 0.90" WC and reset at 0.40" WC, ensuring the inducer motor is moving sufficient air before the ignition sequence initiates. This SPST-N.O. (Normally Open) switch features a durable diaphragm and 12-inch leads for direct integration into the control circuit. Engineered for high-demand environments, the 59W33 serves as a reliable replacement for failing original switches in specific Lennox furnace and heat pump models, preventing dangerous operation under blocked vent or failed inducer conditions. For professional contractors, utilizing this genuine Lennox replacement part ensures exact electrical ratings of 120/240 VAC at 6.0 FLA, maintaining the equipment's original safety specifications and performance standards.
Key Benefits- OEM Precision: Direct replacement for part # 102310-01, ensuring exact physical fit and pressure set points.
- System Protection: Rapidly detects low-pressure conditions to prevent the burner from firing under unsafe venting scenarios.
- Technical Reliability: High-grade SPST contacts and robust housing withstand the thermal cycling typical of HVAC cabinets.
- Simple Integration: Equipped with 12-inch leads and standard mounting holes for efficient field installation.
What causes a Lennox pressure switch to fail or trip?
Common causes include a failing inducer motor, cracked heat exchanger, blocked vent pipes, or moisture buildup in the pressure tubing. If the Lennox 59W33 does not close, verify there is no physical blockage before assuming a faulty switch.
Can I use a generic adjustable switch instead of the 59W33?
Technicians should always use the specific OEM pressure switch because the set points (0.90" WC / 0.40" WC) are engineered specifically for the airflow requirements of certain Lennox units. Using an incorrect set point can result in unsafe operation or frequent nuisance tripping.
How do I test the Lennox 102310-01 switch?
With the system off and leads disconnected, the switch should show an open circuit. During inducer operation, use a manometer to verify the pressure reaches the actuation point, at which time the switch should show continuity.
