Lennox 59W34 Pressure Switch

Lennox 59W34 Pressure Switch

The Lennox 59W34 High Pressure Switch is an essential OEM safety component designed for heavy-duty application in residential and commercial cooling systems. This SPST high pressure control is engineered to monitor high-side refrigerant pressures, providing critical protection for the compressor and system piping. This switch actuates at 640 PSI to immediately open the control circuit and resets at 475 PSI, ensuring the unit stays offline until pressures stabilize to a safe operating range. As a direct replacement for Lennox part number 102311-01, it offers precise HVAC pressure switch calibration to prevent catastrophic equipment failure caused by restricted airflow, overcharging, or condenser fan failure.

For service technicians, this high pressure limit switch features standard lead wire connections for a seamless fit into existing 24V or line-voltage control loops. Utilizing genuine Lennox HVAC parts like the 59W34 ensures that the system maintains its original engineering specifications and safety ratings. When troubleshooting pressure switch trip incidents, verify that the condenser coils are clear and the fan motor is drawing correct amperage before replaces this switch to ensure long-term reliability.

Key Benefits for Technicians:
  • Internal System Protection: Prevents compressor damage by monitoring high-side refrigerant pressure with an actuation point of 640 PSI.
  • Automatic Reset Logic: Features a 475 PSI reset threshold, allows the system to resume safe operation once pressure drops.
  • OEM Compatibility: Precision-matched for Lennox equipment, providing an exact physical and electrical fit compared to universal aftermarket switches.
  • Durable Construction: Built to withstand the high-cycle demands of industrial and commercial environments.
  • Standard Electrical Interface: Rated for 6 Amps at 120/240 VAC, making it compatible with a wide range of control circuits.
Common Questions:

What causes a Lennox 59W34 to trip?
Common triggers include a dirty condenser coil, a failing condenser fan motor, or a refrigerant overcharge. Technicians should also check for non-condensables in the system if the switch trips frequently.

Is the Lennox 59W34 an automatic or manual reset switch?
The 59W34 is an automatic reset pressure switch, meaning it will close the circuit once the system pressure falls below the 475 PSI reset point.

Can this switch be used in 24V control circuits?
Yes, this switch is rated for 24V applications as well as line voltage up to 240V, making it a versatile Lennox replacement part for various HVAC equipment types.
