What is happening, in three sentences
When a DL cabinet is warm and the machine is plainly running, the useful split is between a unit that is not making cold and one that is making cold and losing it. A blocked condenser and a frosted evaporator are the first; a failed door seal is the second. The checks below separate them before anything is replaced.
What you actually observe
- Cold at the bottom of the cabinet and warm at the top — Air is stratifying because nothing is moving it, which is the fan question rather than the refrigerant question.
- A sheet of frost on the back wall of the freezer section — Not the usual light dusting but a solid layer, which blocks the air path rather than cooling it.
- The machine sounds normal but nothing inside is cold — A running compressor proves the motor is turning, and nothing else.
- NEAR MISS — only the ice is soft and everything else is fine — A freezer section that is merely too warm while the fridge section is right is a control or damper question, not a cooling failure.
What it usually turns out to be, in order
- Condenser coil choked, or no clearance around the cabinet — Heat leaves the refrigerant at the condenser, and a coil packed with dust or a cabinet pushed tight into a recess cannot do it. Ranked first here: it is both the commonest cause of this complaint on compact refrigeration and the cheapest to rule out, which is the same reason it belongs before anything requiring a panel.
- Door seal not sealing, or the door not pulling itself shut — A gasket that has taken a set, a door that has dropped on its hinge, or a shelf holding the door open by a fraction all let room air in faster than the machine can take heat out. It ranks second on DL rather than first only because the cause above it is quicker to exclude, not because it is rarer.
- Thermostat, sensor or control set wrong or reading wrong — A dial knocked to its warmest position, or a sensor reading colder than the cabinet really is, both stop the machine asking for cold. Third: real, but it usually announces itself with something the first two causes do not produce, so the earlier checks will have already pointed at it.
What to check first, second, third
- The order for this model group — It is set by access rather than by likelihood alone: on DL the first checks are the ones the cabinet lets you make from where it stands.
- Look at the condenser and at the clearance around the cabinet — Dust on the coil and a tight recess produce the same result, and both are visible without a tool.
- Close the door on a strip of paper and pull — Do it at four points around the frame. A strip that slides out without resistance is the leak.
- Check the setting, then watch whether the machine cycles — Set it to the middle of the range and see whether the compressor responds within a few minutes.
Safety before diagnosis
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off, and on a refrigerator the compressor circuit stays live for as long as the plug is in.

Where the owner fix stops
Two conditions make this a service call rather than a Saturday job: the cause is behind a sealed panel, or the cause is the sealed system itself. Either way the tools are not owner tools and the refrigerant is not owner-serviceable.
