The short answer
When the Caf CQE family stops cooling, start from which compartment went warm first, because on this platform that single observation splits the likely causes in half. The matrix below carries a single model tag, so there is no revision fork to work around on this family: what holds for that tag holds for the line. A freezer that is still hard-frozen with a warm fresh-food section is an airflow or damper fault; both compartments warm together points at defrost, the condenser, or the sealed system.
What you can observe on these models
- Ice cream has gone soft while the cubes in the bin are still solid — The bin holds its own cold for days, so intact cubes prove nothing — the soft ice cream is the real reading.
- Condensation or standing water inside the fresh-food section — Warm humid air is entering and condensing, which usually accompanies a door or gasket problem rather than a component failure.
- The display still shows the set temperature while the food is warm — The panel reports the sensor, not the shelf. A sensor reading out of range will hold a confident wrong number.
- NEAR MISS — the unit is silent and nothing is cold — No hum at all is a power, start-relay or control fault, not a cooling fault. That belongs on the no-power page, not this one.
Causes, most likely first on this family
- Condenser coil fouled or condenser fan not turning — Ranked first because it is the most reversible of the causes and the one most often found on units that sit close to a wall or on carpet.
- Defrost circuit no longer clearing the evaporator — Second: the classic slow-onset fault, confirmed by the fact that an overnight unplug restores cooling for a day or two.
- Evaporator fan motor stopped — Third, and the quickest of the internal checks once the frost question is settled.
- Overloaded cabinet or blocked interior vents — Fourth: packing boxes against the rear vents starves the fresh-food section in exactly the way a failed part would.
Check in this order, and why
- Decide which compartment failed first — Freezer cold and fresh-food warm points at the damper and the air path; both warm together points at defrost, condenser or sealed system. The rest of the order follows from this answer.
- Feel the air at the fresh-food vents — No movement at all is a fan or a closed damper; weak, barely-cool movement is an iced coil.
- Take the freezer rear panel off after unplugging — The coil state is the decisive evidence on this platform, and it cannot be seen any other way.
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
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 CQE 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.
