The short answer
On the AFU platform a freezer that will not hold is far more often a seal, a frost layer or a room than a failed compressor, and on an upright every door opening drops cold out of the bottom of the cabinet, so the gasket and the door habit lead the list. The brand-generic article gives you the standard order; on this kind of cabinet the first two checks are different and they are free.
What you observe on these models
- Thick ice on the shelves and the rear wall — On a manual-defrost cabinet that ice is insulation over the cooling surfaces.
- Ice cream is soft while everything else still seems frozen — Ice cream is the most sensitive thing in any freezer and it warns first.
- Frost building fastest along the line of the lid — That is where the warm air is coming in, and it names the seal without any tools.
- The freezer side is fine and the refrigerator side is warm — On a shared cold source that is airflow, not cooling capacity.
- NEAR MISS — the cabinet is silent and warming — That is a no-power, thermostat or start-relay fault and a different page.
Causes, most likely first on the AFU family
- Door seal and door alignment — First on an upright, because gravity is working against you: every opening drops cold out of the bottom of the cabinet and a gasket that is not sealing does it continuously.
- Frost on the shelves and the rear wall — Second: on a manual-defrost upright, ice builds on exactly the surfaces that are supposed to absorb heat, and the cabinet quietly loses capacity for weeks before anyone notices.
- Ambient temperature and the space around the cabinet — Third: garage installations swing far more than a kitchen and the cabinet follows.
- Thermostat, start relay or the sealed system — Fourth, and the boundary of owner work.
- Ambient temperature where the freezer stands — Last: chest freezers live in garages, porches and outbuildings.
Check in this order, and why that order
- Paper-test the gasket the whole way round the door — Shut a sheet in the door and pull.
- Look at the frost on the shelves and the rear wall — Thick ice is insulation exactly where you need heat transfer.
- Defrost the cabinet completely, then run it empty for a day — On this platform a full defrost is a diagnostic step, not just a chore.
- Repack the cabinet leaving air gaps at the cold surfaces — Packing against the plates is a false economy and it shows up as a cabinet that never quite holds.
- Take an overnight reading with a thermometer in the middle of the load — A freezer holds food safely at 0 °F (−18 °C) or below.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Treat that as the first step of every check below that involves a panel, a grille or a cover.

When to call a technician
On a upright freezer the owner's side of the line is the seal, the frost, the loading, the room and the space around the cabinet. On these models the line falls at the sealed refrigerant circuit and the compressor. Call without working through anything at all for a cabinet that has stopped holding despite a clean seal and a clear frost line.
