What this means on these models
The Comfee CRR refrigerator that will not cool while clearly running is telling you the refrigeration side still works 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. What separates this family from a kitchen refrigerator is the thin margin it keeps for heat rejection.
What the owner sees and hears
- A click every few minutes and silence — This pattern is not the same fault and it promotes the sealed system.
- The complaint appears in hot spells — These cabinets live in unconditioned spaces, and the margin they hold does not stretch.
- Food freezing on one shelf while the rest is warm — That split is the signature of stranded cold: it is being made and not distributed.
- NEAR MISS — the cabinet is cold and only the ice is missing — Keep the two apart — chasing a cooling fault on a cold cabinet wastes an afternoon.
What it usually turns out to be, in order
- Condenser coil buried in lint — Top of the list here: the hot side is the bottleneck of a cabinet this small, and it is the part owners never clean.
- A gasket that no longer holds the door — Door seal climbs on any secondary-location unit, because the room it stands in is harsher than a kitchen.
- An unheated garage or a hot enclosure — Ranked here because it costs nothing to rule out and explains a surprising share of summer call-outs.
The order to work in
- Pull the unit out and inspect the coil — First because the coil is the cause most likely to be found and the easiest to see once the unit is away from the wall.
- Check the gasket with a banknote — Check every side — seals usually fail at one corner rather than everywhere at once.
- Consider the room before opening anything — These models are installed in unconditioned rooms, and a hot enclosure produces this exact complaint with nothing broken.
Safety first, and it is not optional
Safety
Never cut, bend or open the refrigerant tubing — that line is where DIY stops. Coil fins are sharp and the tubing behind them is hot — gloves and a cooled-down machine make this a five-minute job. Keep food safety in view: a refrigerator holds food safely at 40 °F (4 °C) or below, so anything perishable belongs in a cooler with ice until the cabinet is back.

When to call a technician
Do not wait if you see oil around the compressor or find the breaker tripping: oil outside the tubing means the system is open. A frosted evaporator that returns within a week of being cleared needs the defrost circuit tested, which is meter work.
