Lennox Dual Pressure Switch WC

The Lennox Dual Pressure Switch line covers OEM replacement furnace pressure switches (also called two-stage pressure switches or draft pressure switches). They are made for Lennox HVAC equipment. Each switch monitors air pressure in the combustion and venting system. It responds automatically to pressure changes so the unit runs safely.

Key Features:

• Dual, two-stage design that senses two pressure thresholds, measured in inches of water column (WC)
• Signals the control system when pressure moves outside its set range, which helps protect the equipment from unsafe conditions
• Genuine Lennox OEM replacement part, built to the specifications of the original component
• Supports reliable startup and operation of gas furnaces and related heating equipment
• Compact construction that makes replacement simple

Choose the child item whose pressure setting and configuration match your original switch. Replacing a worn or failed pressure switch with a genuine Lennox part helps restore dependable furnace operation and extends equipment life.
