Freezer door difficult to open shortly after closing, or makes a popping sound.

Safety: No electrical work required.

Steps:

• 1. Understand behavior: A temporary vacuum after closing the door is normal as warm air cools and contracts. Wait a minute before reopening.
• 2. Check vents: Ensure any cabinet pressure equalization vents are not blocked by packaging or dust.
• 3. Gasket lubrication: Lightly wipe the gasket with a damp cloth and a small amount of food-safe silicone spray to reduce sticking if it is excessively tight.
