Door seal not tight on upright freezer

Either the door seal is bad or the freezer has a refrigerant leak or a bad compressor. Best to have an appliance tech check it. It won't take him long to locate the issue.

Seal needs to be replaced around door. Make sure magnetic strip is tight against sides of refrigerator, even if you have to cut the outside so it lays flat against the sides.

seal around freezer door may be warped/old/cracked... or thermostat is not working properly.

Try duct taping door as tightly shut as possible and check around the time it freezes to see if that fixes the problem. If so, the seal (that has magnets so it will seal completely) needs to be replaced.

If that doesn't fix the problem, it could be a faulty thermostat in the freezer.

Freezer burn to food is caused by air & moisture in contact with it.
There should be a tight seal by the rubber gasket along all the inside edges of the freezer door. This gasket prevents unwanted hot moisture and hot air from entering the freezer compartment and causing ice build up. You can test the integrity of the rubber gasket seal by seeing how the freezer door will pinch a slip of paper in various spots around the freezer door. If the slip of paper pulls out easily, there is not a good seal at that spot. If that's the case (which I believe it is), the door gasket needs to be replaced. By the way, ice will build up over time because you need to access the food in the freezer, hence you will introduce moist air each time you open the freezer door.

it may take upto24 hours to settle to -18C,remember it has to cool right through the food in the freezer,as well as the walls.also if the food went soft, it is spoilt......cook meat asap then refreeze.

2 months old should still be under warenty.

Check the freezer fan by opening the freezer door and pressing the door switch and listing for the freezer fan sound. If no sound then the fan motor could be bad.

Look at the back wall too see if you have frost build up. If you do then you have a defrost problem.

If thees are not your problem you could have a seal system problem. (( freon leak ))

a leaking gasket can cause food to thaw and it can be fixed if a new gasket is avaliable from local appliance parts place..the gasket is held on by the liner which is removed by gently lifting the gasket and removing the screws..the reverse to install the new gasket

I was hoping it would be something like a cracked door seal, or a faulty thermostat, etc., but after reading the rest of your info, I've concluded the likely cause is a slow leak in the refridgerant line(s). I've seen many of these fairly new upright freezers with this problem.

Finding the leak is easy for a service tech to find, but the cost of the service tech isn't cheap and unfortunately, the repair cost will probably exceed the cost of a new freezer, but you can try to call a repair tech and see if they can give you a rough estimate over the phone or if they think it's worth fixing, etc.

My advice is to replace it. The cost of food you've lost has probably exceeded the price of a new freezer - and you've had this happen twice now. These days it seems that some appliances are being designed and built as "throw aways" due to the high repair cost.

Wished I had some better news for you, but unless you've got all the specialty tools; (charging gauges, vaccum pump, Freon, etc.) needed to do the repair yourself, along with the technical knowledge, it's likely not worth having the repair service contracted. Best Regards.

If the door seal does not seal completely, replace it. This is very important for freezers.
