Start here
The distinction that matters here is between a unit that is not making cold and one that is making cold and cannot deliver it. On this family it is usually the second. Ice sheets across the evaporator, the fan can no longer push air through it, and the compartment climbs even though the compressor never stops. The first two checks below cost nothing and need no tools. The last one is licensed work. One listing carries this family key, so nothing here has to be hedged across generations.
How it presents
- Food in the door is spoiling before food at the back — The door is furthest from the air supply, so a partial airflow loss shows up there first.
- The cabinet recovers overnight and fails again by evening — A marginal system keeping up while the kitchen is cool and losing ground once it warms. It points at heat rejection rather than at the air path.
- A sheet of frost across the back wall of the freezer — Not the usual light dusting that comes and goes, but a solid layer that does not clear between cycles.
- The compressor never cycles off — It runs without ever reaching the set point, which is the same fault seen from the control side rather than the air side.
- NEAR MISS — the cabinet is cold but the icemaker is empty — Cold air with no ice is its own fault path and has its own page for this family.
What it turns out to be, in order
- Airflow blocked by a frosted evaporator — First on this roster, and by some distance. Adaptive defrost on these cabinets stalls before it fails outright, so ice accumulates over weeks and the owner notices the warmth long before the frost.
- Evaporator fan motor failed or obstructed — Second. This fan works in the one compartment that accumulates ice, so it spends its later years pushing against frost, and bearings that live in cold damp air do not last indefinitely.
- Defrost heater, thermostat or timer fault — This is what turns cyclical frost into permanent frost. It is also the point at which looking stops being enough and a meter is needed.
- Sealed-system or compressor fault — Last, and the reason the order matters. It is the least likely cause on this roster and the only one that is not owner-serviceable at any level.
Work in this sequence
- Listen at the freezer with the door open and the switch held in — The evaporator fan should run. Hearing it separates the two likeliest causes before any panel comes off.
- Pull the cabinet out and look at the condenser coil — Dust and pet hair pack into a bottom-mounted coil until it cannot shed heat. This is the one step that is both common and invisible from the front.
- Close the door on a strip of paper at three heights — Paper that pulls out freely anywhere along the seal means the door is not sealing there, and that is a cheap fix that looks like an expensive one.
What to do before the panel comes off
Safety
Nothing below happens with the machine live. Unplug it or switch off its breaker, and treat any capacitor as charged until it has been discharged properly.

The line between a fix and a call
Anything reachable without a tool is yours; anything that needs the rear panel off is a service call on this family, because the panel is foamed against the liner on some of these listings and comes off in one direction only. Refrigerant work is licensed regardless of who is holding the gauges.
