Lennox 32C88 Pressure Switch

The Lennox 32C88 is a genuine 2-stage pressure switch designed for compatible Lennox heating equipment. This Lennox furnace pressure switch monitors inducer-generated draft and provides the control system with pressure verification during the furnace operating sequence.

Unlike a single-stage switch, a two-stage pressure switch supports equipment with separate low- and high-stage operating requirements. Proper pressure-switch operation is critical to the furnace ignition sequence because the control must confirm the required draft conditions before burner operation can proceed.

When replacing the Lennox 32C88 pressure switch, technicians should verify the complete furnace model and serial number along with the original pressure-switch part number. Do not substitute another pressure switch based only on appearance, hose connections, or mounting configuration because pressure set points and equipment applications can differ.

Common Questions

What is the Lennox 32C88?
The Lennox 32C88 is a two-stage pressure switch designed for compatible Lennox heating equipment.

What does a two-stage furnace pressure switch do?
It provides pressure verification for heating equipment with separate operating stages, allowing the furnace control system to confirm proper inducer draft conditions during the ignition and heating sequence.

Can I replace the Lennox 32C88 with a pressure switch that looks the same?
Do not select a replacement based on appearance alone. Pressure switches can have different pressure set points and application requirements even when their mounting and hose connections appear similar.

How do I confirm that Lennox 32C88 fits my furnace?
Verify the complete furnace model and serial number and compare the original pressure-switch part number with Lennox service or parts documentation before ordering.

What should be checked when diagnosing a pressure-switch fault?
Technicians should also inspect inducer operation, pressure tubing, venting, condensate drainage where applicable, electrical connections, and other components that can affect draft pressure.
