The short answer
On the Amana AMAW refrigerator family, a cabinet that runs but will not hold temperature points at the supply and the control state, because a surprising share of these calls follow an outage or a panel that has been pressed into a mode nobody meant to set. The brand-generic article puts a stalled defrost cycle at the top of this symptom; on this platform it sits second, behind causes that are quicker to rule out.
What you observe on these models
- The display shows the set temperature while the shelves do not — What the control believes and what the thermometer says have come apart.
- Frost builds as a sheet on the freezer rear wall — Not the usual light dusting but a solid layer that keeps returning after it is cleared.
- 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.
- 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
- Power interruption, a control left in a showroom mode or a tripped circuit — Ranked first here. After an outage some controls come back in a state that suspends cooling until they are cleared. The lights and the panel work, which is why this is almost never the first thing checked and occasionally the whole answer.
- Defrost cycle stalled and the evaporator iced over — Next. Adaptive defrost degrades before it fails outright, so ice builds on the evaporator over weeks, airflow drops, and the owner notices the warmth long before anyone notices the frost sheet behind the rear panel.
- Condenser coil choked with dust, lint or pet hair — Third in order. 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.
- Temperature sensor or control reading the cabinet wrong — Last, and the least likely of the four. A sensor drifting warm tells the control the cabinet is colder than it is, so the compressor is commanded off early. Nothing sounds wrong, and nothing is cold enough.
Check in this order, and why
- Check the panel for a mode indicator and the circuit for a trip — Start here. Controls can return from an outage in a state that suspends cooling, which looks like a dead system with a live display.
- Take the freezer rear panel off and look for a frost sheet — Then this. A solid sheet across the evaporator is the airflow answer; a light dusting is normal and means keep looking.
- Look at the condenser coil — Third. It is reached without tools on most cabinets and it tells you in one look whether heat can leave at all.
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.
