The short answer
On a 4w3ig80 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.
- Air at the vents is moving but not cold — That points at the coil rather than at the fan.
- NEAR MISS — the unit is silent and nothing is cold — If nothing hums at all, stop here and start there instead.
Causes on the 4w3ig80 listings, most likely first
- Evaporator fan motor failure — The fan sits behind the freezer rear panel and is the moving part that wears on this platform. When the evaporator fan stops, the coil stays cold and the cabinet does not: the cold has nowhere to go. The long revision run above covers a lot of production, and the oldest listings in it reach this point first.
- A door gasket that no longer seals — A gasket that has taken a set lets room air in continuously, which loads the evaporator with far more moisture than it was meant to shed.
- The damper between compartments stuck shut — A jammed or iced damper explains the split symptom exactly: freezer good, fridge warm, compressor running normally throughout.
- The condenser fan not running — The condenser fan pulls room air across the coil and over the compressor, and without it both overheat and the unit protects itself by shutting down.
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.
- Check the door seals with a sheet of paper — Do it at four points on each door rather than one; gaskets fail in patches.
- Confirm the damper between compartments opens — Worth doing early only when the freezer is cold and the fridge is not, and worth skipping entirely when both are warm.
- 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.
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. Call immediately if you see oil at the compressor or smell anything burning: oil outside the tubing means the system is open, and every hour it runs after that costs more to put right.
