Straight answer first
A Comfee CERM refrigerator that keeps running without getting cold inside is hardly ever a dead compressor. The sealed system comes last on this list, not the first, and the checks below are ordered to prove that before anyone pays for it. 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.
