The short answer
Read the ice before you buy a gasket. On a Samsung freezer, frost at one point around the opening is humid air entering there, which is a local gasket failure. Frost spread evenly through the compartment is a defrost problem. And on drawer-style freezers, a basket pushed forward holds the drawer open a few millimetres and produces both.
Causes, ranked for this Samsung freezer
- Contents holding the door or drawer open — Why: On a drawer freezer a basket pushed slightly forward or a package standing proud holds it open a few millimetres, which produces identical frost with nothing at all wrong.
- Gasket hardened or taken a set along a run — Why: Freezer gaskets stiffen in the cold as they age, and a hardened section stops sealing while the rest of the gasket looks identical to the eye.
- Ice on the sealing face itself — Why: Once frost forms where the gasket seats the door cannot close on it, so a small leak grows into a large one and the fault accelerates on its own.
- Cabinet not level, or drawer runners out of alignment — Why: A cabinet standing unlevel or a runner knocked out of true presents the seal out of square, which opens one edge first.
- Gasket or cabinet face dirty — Why: A film on either surface stops a sound gasket pulling in, which is corrected with a cloth rather than a part and is the cheapest thing to eliminate.
What to check, in order
- run the paper test at many points around the opening. — Because: the map of where the seal fails separates a gasket run from geometry.
- note whether frost is local or spread through the compartment. — Because: even frost everywhere is a defrost problem that no seal work will help.
- pull baskets back from the door line and repeat the test. — Because: contents holding the door open is the top cause and it is free to correct.
- clear ice off the sealing faces and dry them. — Because: ice on the seal face prevents closure and worsens the fault daily.
Checks you can safely do yourself
- Close the door or drawer on a strip of paper at several points, noting anywhere it slides out with no drag. — Tools: a strip of paper — Time: several minutes
- Look at where frost has formed and decide whether it is at one point or spread through the compartment. — Tools: a torch — Time: several minutes
- Pull every basket back from the door line and check nothing stands proud, then repeat the paper test. — Tools: none — Time: several minutes
- Clear ice from the gasket and the cabinet face with a cloth and warm water, never a tool, and dry both. — Tools: a cloth and warm water — Time: several minutes
- Check the cabinet is level and that drawer runners are square. Stop here: gasket replacement and runner adjustment are service work. — Tools: a spirit level — Time: several minutes
Before you open anything
Safety
unplug-before-service freezer-0f
Switch the unit off at its breaker before removing any trim or runner cover, and never chip ice with a screwdriver, knife or any metal tool, because the liner and evaporator tubing behind it puncture easily and the repair then ends permanently. Empty a loaded compartment before moving anything.
Where the owner fix ends
Rearranging baskets, clearing ice, levelling and mapping the seal are owner work. Call a technician when a run of gasket has taken a set, when the paper test fails with a level cabinet and clean seal faces, and when frost is even throughout the compartment, since that is a defrost fault rather than a door one.
