Straight answer first
A Comfee CERM refrigerator that keeps running without getting cold inside is hardly ever a dead compressor. These are compact cabinets, so the condenser works in a tight space and the whole refrigeration deck shares one small volume of moving air.
What you actually observe
- The gasket has taken a set or sits proud of the frame — Slip a banknote into the seal and close the door — if it slides out with no drag, that corner is not sealing.
- A solid ice sheet inside the cold section — Frost that returns within days after being cleared is the defrost side failing rather than a door left open.
- No air movement at the vents — A compressor you can hear plus a fan you cannot is the cleanest split between two very different causes.
- Trouble only when the garage warms up — A seasonal pattern points at the coil and the room rather than at a failing part.
- NEAR MISS — temperatures are right, the ice is not coming — Keep the two apart — confusing them wastes an afternoon.
Causes, most likely first on the CERM line
- A dirty condenser — On these compact cabinets the coil has the least margin of any component: a thin layer of dust costs it more here than a thick one costs a full-size unit.
- Defrost cycle stalled, fins packed with ice — Where the model is frost-free, this rises to the top, because it sounds perfectly normal until the ice wins.
- Door seal not compressing — Door seal moves up the list on any secondary-location unit, because the room it stands in is warmer and more humid than a kitchen.
- Evaporator fan stopped — A circulation fan is the one moving part in the cold, which makes it likelier than anything sealed.
Check in this order, and why
- Look at the condenser coil and the space around it — It is first because it needs no tools, and it explains more warm cabinets on this platform than anything else.
- Check the evaporator area for ice build-up — A thin, even dusting is normal; a solid layer that hides the fins is not.
- Check the gasket with a sheet of paper — Do it early, because a bad seal looks like everything else on this list.
Safety first, and it is not optional
Safety
When you clean the coil, brush and vacuum only; damaging a tube turns a free fix into a sealed-system repair. Move perishables to a cooler before you start — a refrigerator holds food safely at 40 °F (4 °C) or below, and a warm cabinet has already stopped doing that. Unplug the refrigerator or kill the circuit before removing any panel; a capacitor can hold a charge after the power is off.

When this stops being a DIY job
A frosted evaporator that ices up again quickly needs the defrost circuit tested, which is a job for instruments. Do not wait if you smell burning or find the breaker tripping: oil outside the tubing means the system is open.
