The short answer
Not cooling on the Caf CWE family usually means the evaporator is buried in frost, the evaporator fan has stopped, or the condenser can no longer shed heat — in that order on these models. Two model tags make up this family in the matrix below: close enough that the checks are common to all of them, far enough apart that parts are ordered by tag. The compressor itself is the least likely of the candidates and the only one that is not an owner-side check.
What you can observe on these models
- The freezer is still hard-frozen while the fresh-food side is warm — Cold is being made; it is not reaching the upper cabinet. Look at the air path, not the compressor.
- A solid sheet of frost across the freezer rear panel — Normal frost is a light dusting that comes and goes. A sheet means a defrost cycle that is no longer clearing it.
- The vents blow air that is barely cool — Airflow exists but has crossed an iced coil, so it arrives without having picked up much cold.
- 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
- Condenser coil fouled or condenser fan not turning — First on these models when the cabinet sides run hot: heat that cannot leave the condenser comes straight back into the cabinet, and the fix is a vacuum and a brush.
- Defrost circuit no longer clearing the evaporator — Second because the overnight-thaw test separates it from everything else on this list without a single tool.
- Evaporator fan motor stopped — Third: listen at the freezer with the door switch held in — no airflow noise there and the rest of the list becomes far less likely.
- Overloaded cabinet or blocked interior vents — Fourth — free to rule out, and it explains a surprising share of the calls that start as a cooling failure.
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.
Before you open anything
Safety
Unplug before any panel comes off — a capacitor can hold a charge after the power is off. Thaw ice off the evaporator with time or a hair dryer on low from a distance, never with a pick or a knife. A refrigerator holds food safely at 40 °F (4 °C) or below and a freezer at 0 °F (−18 °C) or below, so move anything perishable out before you start rather than after, and keep the doors shut while you work.

When to call a technician
The owner line on the Caf CWE family ends where the panel screws do: vacuuming the condenser, clearing the vents, checking the seal and listening for the fan are all yours. Call once the air path is proven clear and the cabinet is still warm, because what remains is the defrost circuit under load, the sensor set or the sealed system. Call immediately — before running it again — if you smell burning, see oil around the compressor, or the breaker trips when the compressor starts.
