Symptoms You May Notice
Audible beeping alarm from the freezer
The freezer emits a repeated beeping sound that escalates in frequency the longer the door remains open.
OF or O F displayed on the control panel
The digital panel shows the door-open code, replacing the normal temperature display.
Frost forming rapidly on interior surfaces
Warm moist air entering through the open door condenses and freezes on interior walls, shelves, and food packages.
Interior temperature rising above set point
The temperature display or a separate thermometer shows the freezer warming above 0 F as warm air continues to enter.
Possible Causes
Door physically left ajar
A food package, ice bin, or shelf item is blocking the door from closing completely, holding it open just enough to trigger the switch.
DIY PossibleWorn or damaged door gasket
The rubber seal around the door edge has lost its flexibility, developed cracks, or is folded under, preventing a tight closure that satisfies the door switch.
DIY PossibleFailed door switch
The magnetic reed switch or mechanical door switch has failed in the open position, falsely reporting that the door is open even when it is firmly closed.
Requires ProfessionalSafe Checks You Can Do
-
1
Close the door and check for obstructions
Open the door fully, check for anything preventing closure — protruding food packages, a displaced ice bin, or items on the door shelves that extend past the edge. Close the door firmly until you hear it click or feel the magnetic seal engage.
On Samsung Bespoke models, ensure the decorative door panel is flush — a misaligned panel can prevent full closure.
-
2
Inspect and clean the door gasket
Run your fingers along the entire perimeter of the door gasket, feeling for tears, cracks, or sections that are folded inward. Clean the gasket with warm water and mild dish soap, then dry thoroughly.
Apply a thin layer of petroleum jelly to the gasket to restore flexibility and improve the seal on aging units.

3
Dollar bill seal test
Close the door on a dollar bill at several points around the perimeter. Pull the bill — you should feel moderate resistance. If it slides out easily at any point, the gasket is not sealing there.
Test at each corner and the midpoint of each side — gaskets often fail at corners first.
When to Call a Professional
Contact a qualified technician if:
- OF alarm triggers repeatedly with the door firmly closed and no obstructions
- The door gasket is permanently deformed and does not create suction when the door closes
- The door itself is misaligned — visibly crooked or not flush with the cabinet
