Check that the door closes without excessive force and that the gasket is not twisted, stretched or outside its channel.

In short: use a paper test around the perimeter, monitor temperature and watch previous ice or condensation points.

Some profiles may relax after transport, so repeat the check the next day. If leakage remains with a correctly seated gasket, inspect hinges, latch, threshold and frame geometry instead of replacing the part again.

First 24 hours

Allow 24 hours for the gasket to settle and take its working shape before making a final seal assessment.
Monitor temperature for the first few days to confirm the door is holding setpoint and recovery times are back to normal.
For freezer doors, apply food-grade silicone lubricant to keep the gasket supple at low temperature and to discourage it from sticking to the frame and tearing on opening.

What a correct fit looks like

A correctly fitted gasket should restore the door to its original seal:

Even compression all round.
A firm drag on the paper-note test at every point.
No light gaps and no frost lines around the frame.

If leaks persist

If leaks persist after a fresh gasket and a hinge adjustment, the door leaf or frame may be distorted. A structural check is warranted before further parts are fitted — adjust the hinges first (see Door problems), then inspect the leaf and frame for warping.

If leaks persist after a fresh gasket and hinge check, contact [email protected] for a profile and door assessment.
