The short answer
On the SR line the useful first fact about a warm cabinet is whether the compressor is still running. One model number carry this family badge, and the matrix on this page is the list. If it is, the refrigerant circuit is almost certainly intact and the cold is being made but not delivered — which puts the fault in the air path and makes three of the four causes below owner-checkable.
What you actually observe
- The cabinet is warm but the unit is clearly running — The unit sounds completely normal, which is exactly why the fault goes unnoticed until food spoils.
- A sheet of frost on the freezer rear wall — Ice forms a slab across the back panel instead of a thin even coat — the tell that airflow has already stopped.
- The fresh-food side warms before the freezer does — On a single-evaporator cabinet the fresh-food side is fed by air from the freezer, so it loses temperature first.
- Condensation or sweating inside the cabinet — Beads of water on the underside of shelves and on the door liner, which is the cabinet sitting above its dew point.
- The back of the unit is unusually hot to the hand — The machine compartment radiates more heat than usual into the room, which is heat that should have gone out through the coil.
- NEAR MISS — the unit is silent and nothing is cold — Silence plus warmth is a start-device or compressor fault, and the checks on this page assume neither.
What it usually is, in order
- Evaporator fan motor failure — First here, because the matrix on this page covers a single build rather than a span of generations — wear on a continuously-loaded motor is the failure that does not care which generation of the family you own.
- Stalled defrost cycle icing the evaporator — Second because it produces the identical complaint with one visible difference: a stalled defrost leaves a slab of ice on the rear panel, and a dead fan leaves the coil clean.
- Air damper or door seal leaking into the cabinet — Third — it explains the split case, where one compartment holds temperature and the other does not, without any fault in the cooling parts at all.
- Sealed-system or compressor fault — Last: least likely of the four here and the only one needing licensed refrigerant work. It is worth reaching only once the three above are clean.
Check in this order, and why
- Hold the freezer door switch in and listen for airflow — The evaporator fan is first because it is the single point that stops cold air reaching both compartments, and it is audible without removing anything.
- Look behind the freezer rear panel for ice — A clean coil with a dead fan and an iced coil with a live fan are two different repairs, and this look separates them.
- Watch the damper between the compartments if the freezer is cold and the fridge is not — Neither fan nor defrost explains a split like that; the air path between them does.
- Leave the condenser until last — A dusty coil makes a marginal system worse rather than producing a completely warm cabinet on its own.
Safety first
Safety
Isolate the appliance at its breaker or unplug it before any panel comes off — a capacitor can hold a charge after the power is off. The rear panel of the freezer carries the defrost heater: treat it as live until the unit is isolated, and let an iced coil thaw on its own rather than forcing it. Never cut, bend or braze anything on the refrigerant circuit.

Where owner work stops
The condition is simple on these models: if the fix needs the freezer emptied and the rear panel off, or any work on the refrigerant circuit, it is a service call. A frost slab you can see, a fan you cannot hear, or a coil you can vacuum are owner territory. Oil at the compressor, a burning smell, or a breaker that trips are reasons to stop and call the same day.
