That is the order on every Miele cabinet in South Florida. It is deliberately the order of increasing cost, and a real share of calls end at step one. ### What actually goes wrong - **A matted condenser**, which imitates everything below it. - **The evaporator fan**, which starves the fresh food side. - **The defrost heater or its sensor**, which builds frost until the air path closes. - **A damper**, which sends cold to the wrong compartment. - **A temperature sensor**, which is what most of this maker’s conditions are. ### Humidity is part of the diagnosis A door seal a fraction proud is tolerable in a dry climate and is a frost problem here within days. So is a cabinet left open during a party. Both look exactly like a failing appliance. What this involves The condenser first, always Sensors read rather than swapped Sealed system excluded before it is ever mentioned The condenser, before anything else On a built-in cabinet in this climate it collects dust that is damp and mats rather than blowing off. A matted condenser produces every symptom on this page and is not a part. Read the sensors Most of this maker's refrigeration conditions are sensors. A cabinet running against a false reading looks like a cooling failure and is a small part. Watch a defrost cycle Frost on the back wall of the freezer with the fresh food side warm is the classic pattern, and it is the heater, the sensor or the timer rather than the compressor. Only then talk about the sealed system It is the row above this one and it is reached by elimination, not by assumption.

Both look exactly like a failing appliance. ### The freezer is fine and the fridge side is warm. That is a specific and useful pattern. It points at airflow between the two compartments — the evaporator fan, the damper, or frost blocking the path — rather than at the compressor, which would take both sides with it. ### How often should the condenser be cleaned here? At least annually and realistically more, because the dust in a South Florida kitchen is damp. It is on the maintenance page for a reason: it is the cheapest thing on this site and it prevents the most expensive. ### There is a code but the food is still cold. Common on this make and worth acting on rather than ignoring. The cabinet is telling you a reading has stopped making sense; it will keep running against that reading until something more expensive gives. --- **[Read full article: Refrigerator cooling & defrost repair](https://mielemiami.support/services/refrigerator-cooling-and-defrost-repair/)**
