The short answer
The 4w5j90 listings are one Amana refrigerator platform, and the model matrix below is the only scope claimed for it. Most calls on it come down to airflow or to water that has left its drain.
What goes wrong, and where it is covered
- Abnormal noise or vibration — A rattle that follows the compressor, or a drumming through the floor. Levelling explains more of these than any part does. — Slug: amana-amana-refrigerator-4w5j90-refrigerator-abnormal-noise-2
- Not cooling or not freezing — Condensation on the shelves and a cabinet that never quite arrives. The seal and the coil are the first two things to rule out. — Slug: amana-amana-refrigerator-4w5j90-refrigerator-cooling-failure-2
- Ice maker fault — Ice production slowing over weeks before it stops. That is a fill restriction rather than a failure. — Slug: amana-amana-refrigerator-4w5j90-refrigerator-ice-production-2
- Water leak or water on the floor — A puddle under the doors or water under the crisper drawers. On these listings the defrost drain is the first thing to rule out. — Slug: amana-amana-refrigerator-4w5j90-refrigerator-water-leak-2
Problem classes in order
- Water leak or water on the floor — High here because the drain is the single point every defrost cycle depends on.
- Not cooling or not freezing — Top of the list: two of its likely causes cost nothing to check.
- Ice maker fault — Ranked by how many listings in the table are plumbed at all.
- Abnormal noise or vibration — Fourth: most noise complaints on this family turn out to be levelling or debris.

Before you start
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Empty the cabinet before walking it out from the wall.
When to call
Most of what goes wrong on this platform is reachable without tools; the exceptions are the evaporator fan and the sealed system. Both need the cabinet opened and running.
