The short answer
On the Caf CVE family a cabinet that is running but not holding temperature is far more often an airflow fault than a dead compressor: the evaporator ices over, the cold stops moving, and the compressor runs on without ever satisfying the sensor. With thirteen model tags in the matrix below, this family covers several passes of the same platform, and a cause that is a running change on one group can be absent on another. Two of the checks that separate those cases need no tools at all, and they are the ones the brand-generic article cannot order for you.
What you can observe on these models
- Cooling recovers for a day after the unit is unplugged overnight — That is the defrost signature: the manual thaw clears the coil, and the fault returns as soon as the ice rebuilds.
- The compressor runs continuously and never satisfies — A unit that never cycles off is not weak — it is being asked to cool through a blockage or a heat load it cannot beat.
- NEAR MISS — the unit cools but rattles or grinds — Noise with normal temperatures is a fan, mount or ice-maker problem; the noise page covers it and this one will not.
Causes, most likely first on this family
- Damper or air diffuser stuck closed between compartments — Ranked first here because it explains the one-compartment failure without invoking any component that would also cool the freezer badly.
- Evaporator frosted by a defrost cycle that no longer completes — Second: ice on the coil starves both compartments eventually, but the fresh-food side shows it first because its share of the airflow is smaller.
- Evaporator fan motor failure — Third because it is easy to confirm by ear and needs no tools until the panel comes off.
- Thermistor or temperature sensor reading out of range — Fourth: a sensor that reads cold when the cabinet is warm makes the control stop cooling on purpose, and every mechanical part will test fine.
Check in this order, and why
- Unplug overnight, then run it and time the recovery — If cooling comes back for a day or two and then fades, the defrost circuit is the cause and nothing else on the list behaves that way.
- Vacuum the condenser and confirm the condenser fan spins — Do this while the unit is already unplugged; it costs one pass with a brush and removes a whole branch of the tree.
- Listen for the evaporator fan on restart — A fan that starts and then falls silent as the cabinet cools is a blade fouling on ice, not a dead motor.

Safety
Unplug the refrigerator or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. The freezer rear panel on the Caf CVE family sits directly over the evaporator fan blade and the defrost heater, so take it off with the power gone and give the coil time to thaw rather than chipping at it: a screwdriver through an aluminium coil turns an airflow fault into a sealed-system replacement. Leave the door switch wired as it is; it cuts the fan for a reason.

When to call a technician
Anything that needs the evaporator cover off, a defrost heater measured, or a sensor compared against its curve is a service call on the Caf CVE family. So is any fault that returns within a week of a manual thaw — that pattern means the defrost control is failing rather than the coil being merely dirty. Stop and call if the compressor starts, hums and stops repeatedly: that is a start device or a locked rotor, and repeated attempts make it worse.
