The short answer
The QT line is a family rather than a single model: the matrix below is the whole of what it spans. Four 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.
What goes wrong on these models
- Runs continuously but the cabinet is warm — The compressor never satisfies because the cold cannot reach the cabinet. — Slug: caf-caf-refrigerator-qt-refrigerator-cooling-failure — Title: Caf QT Refrigerator: Not Cooling or Not Freezing
- 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-qt-refrigerator-water-leak — Title: Caf QT Refrigerator: Water Leak
- 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-qt-refrigerator-ice-production — Title: Caf QT Refrigerator: Ice Maker Fault
- Grinding, buzzing or a rattle that is new — Opening the freezer door cuts the evaporator fan on these models, so a noise that stops the moment the door opens has been located already. — Slug: caf-caf-refrigerator-qt-refrigerator-abnormal-noise — Title: Caf QT Refrigerator: Abnormal Noise or Vibration
Problem classes in frequency order
- Cooling loss and defrost — Ranked first: every other fault on this platform is survivable and this one is not.
- Leaks and drain blockage — Second: 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.
- Ice production — Third: most ice faults resolve at a consumable rather than at a component.
- Noise and vibration — Fourth: noise complaints outnumber noise faults: most are a loose pan or a cabinet out of level rather than a failing motor.
Models in the QT family
Reference| Model number | Family key |
|---|---|
| QT23C_5I_W | caf:refrigerator:qt |

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 |
|---|---|
| Cooling loss and defrost | highest |
| Leaks and drain blockage | second |
| Ice production | third |
| Noise and vibration | 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.
