The short answer
The Caf QC Refrigerator family spans the models in the matrix below, and they share one refrigerator platform. With six 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.
What goes wrong on these models
- No ice, or small and hollow cubes — Look into the mould before anything else: dry is a supply fault, full and unfrozen is a harvest or temperature fault. — Slug: caf-caf-refrigerator-qc-refrigerator-ice-production — Title: Caf QC Refrigerator: Ice Maker Fault
- Runs continuously but the cabinet is warm — Cold is being made and not delivered — a frosted evaporator, a stopped fan or a stuck damper. — Slug: caf-caf-refrigerator-qc-refrigerator-cooling-failure — Title: Caf QC Refrigerator: Not Cooling or Not Freezing
- Grinding, buzzing or a rattle that is new — Time the noise before chasing it: bursts every few hours are the ice maker, a constant rattle is the condenser side, a knock at start is the mounts. — Slug: caf-caf-refrigerator-qc-refrigerator-abnormal-noise — Title: Caf QC Refrigerator: Abnormal Noise or Vibration
- Water under the crisper drawers or on the floor — Usually a defrost drain blocked by an ice plug, which spills meltwater forward instead of routing it to the pan. — Slug: caf-caf-refrigerator-qc-refrigerator-water-leak — Title: Caf QC Refrigerator: Water Leak
Problem classes in frequency order
- Ice production — Ranked first: most ice faults resolve at a consumable rather than at a component.
- Cooling loss and defrost — Second: the defrost and airflow group is what takes a cabinet out of service, so it carries the frequency and the consequence together.
- Noise and vibration — Third: the majority of the noise on this platform is mechanical rattle rather than a component on its way out.
- Leaks and drain blockage — Fourth: the defrost drain is a single point that every defrost cycle depends on, and a plug there shows as water long before it shows as anything else.

Problem classes by relative frequency — No counted component sample covers this family, so the column ranks the classes against each other rather than by share.
General guidance| Problem class | Relative frequency on this family |
|---|---|
| Ice production | highest |
| Cooling loss and defrost | second |
| Noise and vibration | third |
| Leaks and drain blockage | lowest |
When to call a technician
Across these models the same rule holds: if the job needs the evaporator cover off, a part condemned with a meter, or refrigerant touched, it is a service call. Everything upstream of that — supply, filter, drain, seal, level — is yours.
