The short answer
On a 4w7z41 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
- 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.
- Condensation on the cabinet edge or on the shelves — It usually appears at the gasket line first.
- Food spoiling faster than the display suggests — Milk and soft cheese go first.
Causes on the 4w7z41 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. Ice on the coil is the single most common reason one of these runs constantly and still loses ground. This family is a single listing, so what is true of it is true of every unit carrying the badge.
- Evaporator fan motor failure — A failing fan motor gives you a warm cabinet with no frost sheet to show for it, which is what separates it from an iced-up coil. It can chirp or rumble for weeks before it stops.
- A door gasket that no longer seals — A door held off its seal by a shelf, a bin or a crushed gasket costs more cold than any setting change can recover. It is worth ruling out first precisely because it costs nothing to check.
- The condenser fan not running — When this fan stops, the compressor cycles on its overload rather than on the thermostat, so the pattern is long silences between short runs. It is usually debris in the blade rather than the motor itself.
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 door seals with a sheet of paper — Do it at four points on each door rather than one; gaskets fail in patches. A sheet that pulls out with no drag marks the spot.
- 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. Frost around the housing answers it without a teardown.
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. Never chip frost off an evaporator with a screwdriver or a knife: the tubing behind it is thin-walled, and one puncture turns a free defrost into a sealed-system repair.

When to call a technician
The line on these models is the rear freezer panel: everything in front of it is an owner check, everything behind it needs the evaporator exposed and a way to read it. If the fan is silent with the door switch held in, that is a parts job rather than a diagnosis.
