Freezer door is hard to open right after closing, or a vacuum sound is heard.

Safety: No electrical work required.

Steps:

• Wait a moment: It is normal for the door to be harder to open for a few seconds after closing due to pressure changes.
• Clean gasket: Wipe the gasket and mating surface with warm soapy water to reduce sticking.
• Check level: Ensure the unit is level so the door seals evenly.
• Inspect gasket: Replace if warped or excessively sticky.
