Gfwn1100 L1ww Parts

This pressure switch senses pressure changes and sends a signal to the appliance control so systems like water or airflow functions operate correctly. Replacing a faulty switch restores accurate pressure detection and reliable system responses. What it does:

• Detects pressure changes and notifies the control board to start or stop related functions.
• Used where the appliance monitors water or air pressure for proper filling, venting, or diagnostics.
• A failing switch can cause symptoms such as no water/ice fill, error codes related to pressure or fill, or irregular cycling of the affected system.
• Works as a direct replacement for the same OEM part number to restore original operation when compatible.

• Always disconnect power to the appliance and shut off the water supply before starting work.
• Take a photo of the wiring and hose routing before removal to ensure correct reinstallation.
• Avoid kinking or stretching any attached pressure hose; ensure hose connections are secure and free of debris.
• After installation, restore power/water and run a test cycle to confirm proper operation and check for leaks.
