What this usually is
Start with an evaporator fan that has stopped turning: on the MTF models it accounts for more of this complaint than the rest of the list put together. The models here are one machine in several finishes rather than several machines, so the design-inherent causes rank first and the installation causes fall back.
What the owner actually sees
- Frost builds as a sheet on the back wall of the freezer — Not the usual light dusting — a solid skin you can knock with a knuckle.
- The compressor never seems to stop — It runs and runs without reaching temperature, which is the same fault seen from the other side.
- Ice cream has gone soft but frozen food is still solid — A freezer a few degrees warm reads exactly like this before anything thaws.
- NEAR MISS — the unit is silent and nothing is cold — That is a no-power or start-circuit fault, and it belongs on a different page.
What it usually turns out to be, in order on the MTF line
- An evaporator fan that has stopped turning — Ranked first here — it is a moving part under frost and it produces the same warm cabinet from a different component.
- An air damper stuck between the two compartments — Second here — it explains the split case — a freezer holding while the fresh-food side climbs — and not the case where both are warm.
- A condenser fan that is not running — Third here — it has the same effect as a blocked coil, and the two are checked in the same minute at the same panel.
- A leak or restriction in the sealed system — Fourth here — it is the least likely of the list and the only one that is not an owner check.
- Body: These are finish variants of a single build, so a fault found on one of them will be found on the rest, and the order reflects that rather than hedging. One swap follows from that: an air damper stuck between the two compartments ahead of a condenser fan, which is not where a generic list would put either.
What to look at first, second, third
- Open the freezer door, hold the door switch in and listen for the fan — A fan you cannot hear with the switch held in separates this cause from the other likely one before any tool comes out.
- Compare the two compartments before anything else — One cold and one warm points at the damper; both warm points back up the list.
- With the compressor running, feel for airflow at the back or under the toe grille — Still air with a hot compressor is the fan, not the coil.
- Leave this one to a technician — It is confirmed with gauges on a system that must then be recovered and recharged, which is licensed work.
- Body: These are finish variants of one machine, so access is identical across the line and the order below is purely about likelihood rather than about what is easiest to reach. Every check pairs with the cause at the same position, which is what makes a negative result useful rather than merely disappointing.
Switch it off first
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Leave the door switch wired as it is, and never run the cabinet with a panel off to watch it work.

Where owner work stops
Call once the owner checks above come back clean, and call at once if the fault is on the sealed system — refrigerant work is licensed work and the tools for it are not owner tools. Oil at the compressor, or a burning smell from the back of the cabinet, is a stop-now condition: every hour it runs after that costs more to put right.
