Amana-Goodman 11177113 Dual Pressure Switch Gray -0.75" WC

The Amana-Goodman 11177113 is a dual pressure switch designed for residential and light commercial HVAC applications. This gray pressure switch monitors both positive and negative pressure differentials to ensure safe and efficient furnace operation.

Key Features:

• Dual pressure sensing capability for enhanced safety monitoring
• Pressure setpoint: -0.75" W.C. (water column) on both circuits
• Gray housing for easy identification
• Direct OEM replacement for Amana and Goodman furnaces
• Ensures proper inducer motor operation before gas valve activation
• Factory-calibrated pressure settings for reliable performance

This pressure switch is a critical safety component that prevents furnace operation when improper venting conditions exist. The dual-circuit design provides redundant pressure monitoring to verify adequate draft and proper combustion air flow. When the pressure differential falls below the -0.75" W.C. setpoint, the switch contacts close to allow the heating sequence to continue.
