The short answer
A HE cabinet that runs but never gets cold is usually failing at the door or at the condenser, not at the compressor. The brand-generic article puts a stalled defrost first; on this family the cabinet is small enough that a seal which no longer grips, or a grille packed with dust, starves it faster than frost ever does.
What you observe
- The cabinet is warm while the unit is clearly running — You can hear or feel the compressor working, but the air inside never gets cold.
- A sheet of frost on the inside rear wall — A light dusting is normal. A solid sheet means the air path is closed and cold is no longer moving into the cabinet.
- It runs for a short spell, stops, and starts again quickly — Short cycling is a different pattern from continuous running and points at the start components or at overheating rather than at airflow.
- One compartment is cold and the other is not — On models with a separate freezer section, cold in one and warm in the other points at airflow between them rather than at the compressor.
Causes, most likely first
- A condenser coil or grille blanketed in dust — Ranked first on this family. The condenser is small, it is close to the floor or the wall, and the clearance around it is measured in fingers.
- A door seal that no longer grips along its whole length — Second, and the cause owners most often miss. A compact cabinet loses its whole reserve to a small leak, and the seal on a light door takes a set if the unit has been transported or stored shut.
- Start relay or overload protector — A compressor that will not start, or that starts and drops out again after a few seconds, is usually its start components rather than the compressor itself. The tell is the short repeated cycle rather than continuous running.
- A sealed-system or compressor fault — Last, and the reason the order above matters. It is the least common of these causes on this family and the only one that is not owner work at all - refrigerant is licensed work.
Check in this order
- Check where the control is set and whether it has been knocked — A knocked dial is the one cause that looks exactly like a failed platform and costs nothing at all.
- Look at the condenser grille and the space behind the cabinet — Dust here is the first-ranked cause on this family, and the check needs a torch and nothing else.
- Put a separate thermometer in the cabinet and read it after some hours — It separates a cabinet that is genuinely warm from one whose control display is wrong, and it costs nothing.
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. On a compact cabinet the compressor and its start components sit within reach the moment the rear cover is off, so treat the back of this platform as live until it is isolated.

When to call
Call once the door, the clearance and the condenser are all clean and the cabinet still will not hold temperature. That is the point at which the remaining causes are inside the machine.
