Ice buildup on the door gasket or around the door opening; door may be hard to close fully.

Safety first: Unplug the freezer if you need to remove the door or hinges.

Steps:

• Inspect gasket: Look for visible gaps when the door is closed. Use a flashlight inside the cabinet in a dark room to see if light leaks around the gasket.
• Clean and soften: Clean the door gasket and warm it gently with a hair dryer to help it relax and seal better. Do not overheat.
• Check for obstructions: Rearrange items so nothing presses against the door from inside.
• Adjust hinges: Tighten hinge screws and adjust the door so it is square with the cabinet.
• Replace gasket: If the gasket is damaged or will not seal, remove it from the door channel and install a new Insignia-specific gasket, pressing it fully into the groove.
