The short answer
When a 4w3in62 refrigerator runs continuously and still drifts warm, the fault is usually upstream of the compressor. The generic Amana answer treats the compartments as one problem; on this platform the fresh-food side and the freezer fail apart, and which one is warm decides where you look.
What you actually observe
- The cabinet is warm while the unit is clearly running — You can hear it working and feel nothing for it.
- Condensation on the cabinet edge or on the shelves — Warm humid air is getting in somewhere and condensing on whatever is still cold.
- Ice cream goes soft while cubes still form — The freezer is losing a few degrees rather than failing outright.
- NEAR MISS — the unit is silent and nothing is cold — That is a no-power or start-relay fault and it is a different page.
Causes on the 4w3in62 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. The short revision run in the table above means these units left the line close together, so they wear at much the same rate.
- The damper between compartments stuck shut — A jammed or iced damper explains the split symptom exactly: freezer good, fridge warm, compressor running normally throughout.
- 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.
- A failed start relay or overload — The relay gets the compressor turning, and when it fails the machine clicks every few minutes and never runs long enough to cool.
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.
- 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. 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. A refrigerator holds food safely at 40 °F (4 °C) or below, so move perishables to a cooler before you start rather than after.

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. Call the same day if the compressor is hot enough that you cannot keep a hand on it, or if the breaker trips when it tries to start.
