The short answer
On a 4w3n80 refrigerator this almost always turns out to be air that has stopped moving rather than cold that has stopped being made. The brand-generic article ranks a failed compressor high because it has to cover every Amana platform at once; on this one the airflow path is the part that fails first. Most of the checks below need no tools at all.
What you actually observe
- The freezer is cold but the fresh-food side is not — One compartment in spec and the other not is a routing symptom, not a cooling one.
- A sheet of frost on the back wall of the freezer — A solid sheet rather than the usual light dusting.
- Ice cream goes soft while cubes still form — This is the earliest warning the cabinet gives.
- NEAR MISS — the unit is silent and nothing is cold — If nothing hums at all, stop here and start there instead.
Causes on the 4w3n80 listings, most likely first
- Frost blocking the evaporator — Adaptive defrost on this platform stalls before it fails outright, so ice builds over weeks while the cabinet drifts warm a degree at a time. A stalled defrost cycle lets the evaporator glaze over, and once the fins bridge with ice no amount of run time moves cold air into the cabinet. The long revision run above covers a lot of production, and the oldest listings in it reach this point first.
- Evaporator fan motor failure — When the evaporator fan stops, the coil stays cold and the cabinet does not: the cold has nowhere to go.
- A condenser coil packed with dust — Dust on the condenser raises head pressure until the unit is running most of the day and still losing to the room.
- The damper between compartments stuck shut — A jammed or iced damper explains the split symptom exactly: freezer good, fridge warm, compressor running normally throughout.
Check in this order, and why
- Listen at the freezer for the evaporator fan — Hold the door switch in so the fan is allowed to run; it separates the two likeliest causes before any tool comes out. Silence with the switch held is a result, not a non-result.
- Check the condenser coil and the condenser fan — Do this before anything behind a panel, because it is free, quick, and fixes more of these than any single part. The coil is at the back or underneath depending on the listing.
- Check the setting and rule out showroom mode — It sounds trivial, and it is the check that saves a call often enough to be worth one minute. A power cut can leave the control in a display state.
- Leave a thermometer in the cabinet overnight — A single reading tells you little; a reading taken after the door has been shut for hours tells you whether the control is lying. Use a glass of water so the reading is not chasing the door.
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. Pull the cabinet out squarely rather than walking it on its corners; on a loaded unit the door can swing as the weight shifts.

When to call a technician
Call once the airflow checks are clean and the compartment is still warm, because everything left below that point is sealed-system work. Refrigerant is licensed work and the gauges to diagnose it are not owner tools.
