What this family is
the CERT line covers the three model numbers in the table below and nothing beyond them. One series, several numbers: the table below is a run of closely related builds. No fault distribution is recorded for this family, so read the order as an argument rather than a measurement.
The problems these models actually have
- the CERT line making a new noise — Time the noise: constant, only while running, or only at start narrows it faster than how loud it is. Its page: Abnormal Noise or Vibration.
- the CERT line running warm — On the CERT line it usually shows as a gradual loss rather than a sudden one. Go to Not Cooling or Not Freezing.
- Ice production problems — On the models in this table that have one, the ice maker is the most complained-about single component. Go to Ice Maker Fault.
- Leaking inside or on the floor — Condensation on the outside of the cabinet is not a leak at all, and separating the two takes a dry cloth. Water Leak carries it.
The problem classes in order
- Noise and vibration — First on this platform. The sound itself is the diagnosis here more than anywhere else on this list.
- Loss of temperature control — Second. On a Comfee cabinet of this size, airflow alone accounts for a great deal of it.
- The ice maker — Third here. Keep the freezer at 0 °F (−18 °C): an ice maker in a warm freezer fails before its mechanism does.
- Drainage and condensation — Fourth on this platform. A refrigerator makes its own water, so a blocked defrost drain accounts for most of it.

Relative ranking only; this family carries no measured fault distribution
Documented| Problem class | Relative rank on this family | What the rank rests on |
|---|---|---|
| Noise and vibration | highest | how often it is reported, and how cheaply it resolves |
| Temperature faults | second | what it costs an owner while it waits |
| Ice maker faults | third | applies only to the models that have one |
| Leaks and pooling water | fourth | damage outside the cabinet, not frequency |
What an owner can fix on these models
The free checks resolve a real share of all four classes above. Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Call at leisure for noise that comes with a cabinet still holding temperature.
