Was the lid just opened?

When the lid is opened cold air flows out, of the freezer, and warm humid air flows in.  When the lid is closed, the warm air mixing with the cold air creates a vacuum, causing the lid to be harder to re-open.  Allow the internal pressure to equalize before re-opening the lid, this should take less than a 1 minute.  This is part of normal operation and is more likely to occur during the warmer humid times of the year.

Are the gaskets dirty?

The gaskets need to be cleaned in order for the lid or door to open and close properly. Dirt and other particles can build up on the gasket surface and can cause resistance. Check the lid gasket regularly to ensure it is clean and free from food particles.

Is the freezer level?

It is important to ensure the freezer is level to allow the door to open and close properly. A properly leveled freezer will also help with overall proper operation. Please refer to your Owner's Manual or Installation Instructions for specific leveling information for your freezer. 

In addition to your Owner's Manual and Installation Instructions, here are some other tips for leveling the freezer: 

• Use a level to make sure the freezer is level from side to side and front to back.
• Check to make sure the floor under the freezer is also level. If the floor is not level shims may need to be used.
