The short answer
When the Caf CHE 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
- 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.
- The cabinet sides feel hot to the hand — Condenser tubing runs through the shell on many builds; heat there says the system is working hard against a fouled condenser.
- 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
- 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
- Listen at the freezer for the evaporator fan — On these models the fan is behind the freezer rear panel and the door switch cuts it, so hold the switch in to hear it. This one check splits the two likeliest causes.
- Look at the freezer rear panel for a frost sheet — Frost across the panel with the fan running is the defrost signature; a clear panel with no airflow is the fan.
- Pull the unit out and feel the condenser — Heavy dust, or a condenser fan that is not turning, caps the capacity no matter how healthy the rest is.
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 CHE 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.
