The short answer
On the AVFF family this is far more often a heat-rejection or an air-path problem than a dead compressor, and the frost-free compact refrigerator construction is why. Frost-free construction means there is a defrost cycle to stall, and a stalled cycle is the fault this platform produces most.
What you observe on these models
- A sheet of frost across the rear panel of the freezer side — Not the usual light dusting: a solid sheet means the defrost cycle has stalled.
- One compartment is right and the other is not — On a shared-evaporator cabinet this is the single most useful observation available.
- The vent between the compartments is blocked by a tall item — Free to see, free to fix, and it accounts for a real share of calls.
- The cabinet holds overnight and drifts through the day — That pattern is about the room and the door use rather than the machine.
- NEAR MISS — the cabinet is silent and nothing is cold — That is a no-power, cold-control or start-relay fault and it belongs on a different page.
Causes, most likely first on the AVFF family
- A stalled defrost cycle icing the evaporator — First on this platform: heat stops crossing the iced coil, airflow collapses, and the cabinet warms while the compressor runs continuously.
- Evaporator fan motor — Second: on a frost-free cabinet all of the cold is delivered by that fan.
- Cold control, start relay or the sealed system — Third: a cabinet that is uniformly, gently too warm is a control story; a cabinet that is not cold at all with a silent compressor is a relay or a sealed-system story.
- The cabinet has been overfilled — Fourth: a box pushed against the back wall or a shelf packed solid stops air moving past the cold surface, and the cabinet then cools its packaging instead of its contents.
- Where the cabinet is standing — Last: beside an oven, against a radiator, in a sunlit corner or in an unventilated cupboard, the machine is fighting a load it was never specified for.
Check in this order, and why that order
- Open the freezer side and look at the rear panel for frost — A sheet of ice rather than a light dusting names the defrost fault immediately, and this is why the look comes before every test.
- Listen for the internal fan, then open the door and listen again — The fan should stop when the door opens.
- Paper-test the seals on both doors — Moisture entering past a seal is the fuel for the icing you just looked at, so the two checks belong together.
- Clear the condenser and check the machine compartment fan — Now, not first, because on a frost-free cabinet it is a slower and rarer path to the same symptom.
- Thermometer overnight in each compartment — A refrigerator holds food safely at 40 °F (4 °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. On this platform there is no check worth doing that cannot wait the thirty seconds it takes to isolate the machine properly.

When to call a technician
The line on a frost-free compact refrigerator is the rear panel and the sealed system. On these models the line falls at anything behind a panel and anything on the sealed system. Call without working through anything at all for frost or ice returning within days of being cleared, together with a cabinet that will not hold.
