What this means on these models
The Comfee CERS refrigerator that stays warm with the compressor working is telling you the refrigeration side is alive and something downstream of it is not. Heat that has nowhere to go comes right back inside, which is the whole of this fault on a unit this size. The models this page covers are second refrigerators in most homes, asked to hold temperature in rooms a kitchen unit never sees.
What you actually observe
- The outside skin is hotter than it should be — Warmth there is normal; heat you cannot touch means the coil is rejecting into a space that has no airflow.
- One zone cold, the next warm — A single cold spot near the evaporator while the rest climbs is the clearest version of this.
- It cools fine in winter and fails in summer — If the fault comes and goes with the season, start outside the box rather than inside it.
- NEAR MISS — the unit appears entirely lifeless — A dead cabinet and a warm one that runs are two different faults with almost no overlap.
What it usually turns out to be, in order
- Heat rejection stopped at the condenser — It ranks at or near the top on this family because the coil sits in a small, low-airflow space where household dust settles and nothing sweeps it off.
- Warm air leaking past the door — With a small cold volume, a slow leak of room air swamps the machine far faster than it would on a large cabinet.
- The space around the unit working against it — Ranked here because it costs nothing to rule out and explains a surprising share of seasonal complaints.
What to check first, second, third
- Look at the condenser coil and the space around it — It is first because it costs nothing, and it explains more warm cabinets on this platform than anything else.
- Check the gasket with a banknote — Two minutes, no tools, and it removes the fault owners skip on small cabinets.
- Consider the room before you take a panel off — Give it clearance on all sides and see whether the complaint follows the weather.
Safety first, and it is not optional
Safety
Coil fins cut and the tubing behind them is hot — gloves and a cooled-down machine make this a five-minute job. Pull the plug before any panel comes off — a capacitor can stay charged after the power is off, and the starting components sit behind that cover. Deal with the food first: a refrigerator holds food safely at 40 °F (4 °C) or below, and a cabinet that is not holding it is a food-safety question before it is a repair one.

When this stops being a DIY job
Once the diagnosis points at a heater, a terminator or a control board, the parts are cheap and the testing is not owner work. Do not wait if you see oil around the compressor or find the breaker tripping: oil outside the tubing means the system is open.
