Door seals keep cold air in your fridge or freezer and warm air out, so if your appliance isn’t keeping your food cold – or worse still food is perishing – then you should get the seal checked to see if it’s still working. Read on for our experts’ top tips on what to look out for.

Does it have mould around the edge?

Mould typically grows in warmer areas, so if you see any around the edges of your fridge or freezer, it’s probably a sign that you have a problem with keeping warm air from around the fridge or freezer door deal. Have a deeper look at the seal, as this is what keeps the warm air out and the cold air in.

Is food staying cold?

If your food isn’t staying frozen in the freezer, that’s a good indication that something is wrong! Warm air can creep into the appliance, and it’s clearly more likely to happen when the freezer door seal isn’t doing its job.

Does the door seal look damaged?

Visible damage of the seal, such as splits or tears, are the clearest ways to tell if a seal needs replacing. Obviously if it looks like it’s wearing thin, it’s probably a good idea to consider a replacement; have a look and see if you can identify any obvious wear and tear.

How old is it?

It may come as no surprise to find out that older fridges and freezers have weaker door seals. Consider how old your appliance is and if you’ve had it a long time, maybe look at getting the seal replaced to avoid having any issue with it in future.
