Replace a freezer door gasket when it no longer pulls flat onto the cabinet: frost builds up, the door doesn't close by itself or a paper slides out freely. Freezer gaskets are flexible PVC profiles with a magnetic strip inside; they differ by fixing (push-in dart, screw-on flange, self-adhesive), bellows size and magnet position, so match the old gasket's cross-section and the door's inside dimensions.
IllustrativeCheck the gasket
- Paper test: close the door on paper at several points; it should grip.
- Light test: a torch inside the closed freezer in a dark room shows gaps.
- Look: tears, a hardened bellows, a corner that won't spring back.
Identify the fixing
| Fixing | What it looks like | Common on |
|---|---|---|
| Push-in (dart) | Barbed foot pushed into a groove in the door liner | Most domestic fridges and freezers |
| Screw-on | Flat flange held by screws under a retainer | Commercial cabinets, display coolers |
| Self-adhesive | Flat base with tape | Simple doors, retrofit |

Quick questions
Can a freezer gasket be fixed instead of replaced?
A twisted gasket can sometimes be reshaped with warm air; torn or hardened gaskets must be replaced.
Are freezer and fridge gaskets the same?
Same principle, but the section and size vary by cabinet – always match the old one.
Need a seal for this?
Send your section, gap size or a photo of the old seal – Dora replies usually within 2 hours. Fridge & freezer door gaskets are available from 10 m.
