Straight answer first
The Comfee CERR refrigerator that stays warm with the compressor working is telling you the refrigeration side still works and something between it and the food 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 full-size unit is the thin margin it keeps for heat rejection.
What you actually observe
- It never stops and never gets cold — You can feel and hear the machine working, and the shelves never chill anyway.
- Trouble only when the garage warms up — A seasonal pattern points at heat rejection or ambient rather than at a failing part.
- One zone cold, the next one not — A single cold spot near the evaporator while the rest climbs is as clear as this fault gets.
- NEAR MISS — temperatures are right, ice production is not — Keep the two apart — chasing a cooling fault on a cold cabinet wastes an afternoon.
Causes, most likely first on the CERR line
- Ice blocking the air path after a defrost failure — Ranked here because the symptom and the cause are weeks apart, which is what makes owners misread it.
- Evaporator fan failing — Where it applies it beats the compressor on likelihood, since a stopped fan strands cold completely.
- Heat rejection stopped at the condenser — It ranks first on this family because the coil sits in a small, low-airflow space where household dust settles and nothing sweeps it off.
Check in this order, and why
- Check the evaporator area for ice build-up — If ice is present, note how long since the cabinet was last thawed — that dates the fault.
- Listen for air movement inside the cold compartment — Skip this step on a static cabinet — there is no fan to hear.
- Look at the condenser coil and its clearance — It is first because it needs no tools, and it explains more warm cabinets on this platform than anything else.
- Check the gasket with a banknote — Check every side — seals usually fail at one corner rather than everywhere at once.
What to do before the panel comes off
Safety
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. Coil fins are sharp and the tubing behind them is hot — gloves and a cooled-down machine keep this simple. 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.

When this stops being a DIY job
Bring a technician in when the free checks are exhausted rather than before — they narrow the visit. A cabinet that blows a fuse is an electrical fault and belongs to a technician the same day.
