Lennox 23W26 Pressure Switch

Lennox 23W26 Pressure Switch

If you are troubleshooting a refrigerant circuit on a 13ACD or XP21 series unit, the Lennox 23W26 Pressure Switch is the OEM replacement part required to maintain system safety and ASHRAE standards. This low pressure switch is a normally closed component designed for auto reset operation, specifically engineered to open the circuit and stop the compressor when suction pressure drops below the critical 40 PSI threshold. By preventing the system from operating in a vacuum or under low-charge conditions, it effectively mitigates the risk of compressor overheating and oil slugging.

The Lennox 23W26 (also identified as 100087-06) features an actuation point of 40 PSI and a reset point of 25 PSI, providing reliable low pressure cutout protection across various residential and commercial HVAC units. Constructed by Sensata (Model PS80-06-F0012) with 45-inch leads and a contact rating of 120/240VAC at 5.8 Amps, this switch ensures seamless integration with Lennox, Allied Air, and Concord systems. For technicians, using genuine Lennox parts ensures precise calibration and long-term compatibility, critical for preventing nuisance trips and protecting the evaporator coil from freezing.

Key Benefits
  • Precise Pressure Calibration: Precisely opens at 40 PSIG and resets on rise at 25 PSIG to keep the refrigerant cycle within safe operating parameters.
  • Broad Compatibility: Genuine OEM replacement for Lennox, Allied, Armstrong, Ducane, and Magicpak equipment.
  • Heavy-Duty Contact Rating: Standard 120/240VAC FLA 5.8 Amp rating allows for direct integration into most control circuits.
  • Durable Construction: Engineered to withstand high-pressure spikes up to 595 PSIG without compromising sensing accuracy.
  • Efficient Install: Comes with 45-inch factory-installed leads for simplified wiring and field replacement.
Common Questions

Is the Lennox 23W26 an auto-reset or manual-reset switch?
This is an auto-reset low pressure switch. It automatically re-engages the circuit once the system pressure rises back to the reset threshold (25 PSI), allowing for normal operation without manual intervention after a temporary pressure dip.

What happens if I use a generic low-pressure switch instead of the 23W26?
Using generic parts can lead to calibration drift. The Lennox 23W26 is calibrated specifically for the thermal expansion and compression ratios of Lennox-brand equipment, ensuring the compressor shuts down exactly at 40 PSI to prevent equipment damage.

Can this part be used for high-side pressure monitoring?
No, this is strictly a low pressure switch. With a 40-25# range, it is intended for the suction side of the refrigeration cycle. Using it on the high-side would cause immediate and constant circuit interruption.
