The short answer
On the Amana 4w9g00 refrigerator family, a cabinet that runs but will not hold temperature points at the condenser fan, because the sound of these machines changes before the temperature does and owners usually date the fault to that change. The brand-generic article puts a stalled defrost cycle at the top of this symptom. It does not lead here, and on these models it is not what the first three checks are looking for.
What you observe on these models
- The outside of the cabinet is hot to the hand — Heat that has nowhere to go stays in the cabinet walls, and it is felt most at the sides.
- The compressor never stops — It runs without ever reaching temperature, which is the same fault seen from the other side.
- The cabinet is warm but the machine is plainly running — The hum is there and the lights are on; the air inside is not cold.
- NEAR MISS — water on the floor with the temperature correct — That is a leak, and the cause list for it is a different one.
Causes, most likely first on this family
- Condenser fan slowed, stalled or fouled — First on this platform. A fan that no longer moves air across the coil produces the same warm cabinet as a dirty coil, but it usually comes with a change in the sound of the machine rather than a gradual slide.
- Condenser coil choked with dust, lint or pet hair — Second on these models. The coil is the only place heat leaves the cabinet. Once it is blanketed the compressor runs longer and longer for less and less cooling, which is exactly the pattern of a unit that hums all day and never gets cold.
- Start relay or overload protector on the compressor — Third, and less common than the two above. A failing relay lets the compressor try to start, trip and rest in a cycle of a few minutes. The cabinet drifts warm while the machine still makes periodic noise, so it does not read as dead.
- Sealed-system fault — a refrigerant leak or a restriction — Last, and the only one of the four here that is not owner work. The compressor runs and the coil never gets properly hot, or gets hot in one patch only. It is the one cause on this list that is licensed work rather than owner work.
Check in this order, and why
- Watch the condenser fan while the compressor runs — Start here. A fan that is not turning, or turning against debris, is visible from the same access panel as the coil.
- Look at the condenser coil — Then this. It is reached without tools on most cabinets and it tells you in one look whether heat can leave at all.
- Note whether the compressor starts, runs briefly and stops — Third. A short cycle repeating every few minutes is a start-circuit signature and is nothing like a fan or airflow fault.
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.

When to call a technician
Call once the owner-side checks above are clean, and call straight away if the fault is on the sealed system: refrigerant work is licensed work and the tools for it are not owner tools.
