The short answer
On the CWC line, a cabinet that hums but will not hold temperature is far more often an airflow or heat-rejection problem than a dead compressor — the machine is still working, it just cannot move the heat out. On this page the control and the setting are cleared first, because they are the only cause that can be excluded from the front of the cabinet.
What an owner actually observes on the CWC line
- The outside of the cabinet or the door frame is hot to the touch — Hot condenser tubing runs through the sides of many cabinets; hot beyond warm means heat is not being rejected.
- Condensation or sweating on the inside walls — The cabinet is running above dew point for the room, which is the same fault seen from the humidity side.
- NEAR MISS — the cabinet is silent and nothing is cold — That is a no-power, start-relay or control fault and it is a different page: it starts with the outlet and the cord, not with the airflow checks below.
The ranking for the CWC line, likeliest first
- The control is being told the wrong temperature — sensor, thermostat or setting — Ranked first on the CWC line because it is the only cause on this list that a reset and a look at the setting can both confirm and fix, and because a cabinet that satisfies early behaves exactly like one that cannot cool.
- The door is not sealing — gasket, alignment or a shelf holding it open — A door held fractionally open by an over-packed shelf, a tired gasket or a cabinet out of level loads the system permanently.
- The condenser coil is blanketed in dust, or its fan has stopped — Heat has to leave the cabinet somewhere.
- Defrost has stalled and the evaporator has iced over, so no air moves — Last of the airflow causes here: the symptom is unmistakable once a panel is off — a solid slab of ice on the coil — so it is worth confirming only after the checks that need no dismantling.
The diagnostic order, and the reason for it
- First — read the set point and compare it with a thermometer left inside — Put a thermometer on a middle shelf for a few hours.
- Then — close the door on a sheet of paper and pull it out — Do it at the top, the middle and the bottom of each door.
- Only then — find the condenser coil and its fan, and look — Pull the cabinet out or take the base grille off.
- STOP here if the next check needs a panel off or a meter on live terminals — Everything above can be done with nothing dismantled; past it the checks need test equipment.

Read this before any panel comes off
Safety
Unplug the appliance or switch off its breaker before any panel comes off — a capacitor can hold a charge after the power is off, and the compressor circuit is live whenever the cabinet is plugged in even when it is silent. Do not defrost a coil with a heat gun or a sharp tool: puncturing an evaporator tube turns a service call into a replacement.
When it stops being an owner job
Call once the checks above are clean, or as soon as the evidence points inside the sealed system: refrigerant work is licensed work and the gauges to do it are not owner tools. On the CWC line, call rather than continue if the coil has to come out to be cleared, if the fan needs the evaporator cover off, or if the cabinet trips the breaker when it starts.
