Lennox 10U94 0.90" WC SPST Pressure Switch

The Lennox 10U94 is a single-pole single-throw (SPST) pressure switch designed for use in Lennox HVAC furnace systems. This safety component monitors pressure differentials to ensure proper furnace operation and safe combustion.

Key Features:

• 0.90 inches water column (WC) actuation pressure setting
• SPST (Single Pole Single Throw) switching configuration
• Genuine Lennox OEM replacement part
• Direct replacement for failed or malfunctioning pressure switches
• Critical safety component for proper furnace operation

This pressure switch is an essential safety device that monitors the pressure created by the draft inducer motor. When proper pressure is achieved, the switch closes to allow the furnace control board to continue the heating cycle. If insufficient pressure is detected, the switch remains open and prevents the ignition sequence, protecting against potentially dangerous conditions.

Designed specifically for Lennox furnace systems, the 10U94 ensures reliable performance and proper fitment. Professional installation by a qualified HVAC technician is recommended for proper system operation and warranty compliance.
