A FlexZone set to refrigerate is doing exactly what it was asked to do, and it is the single most common explanation for a freezer that stopped freezing overnight with no other symptom. ### What it usually means, by the kind of Samsung appliance Samsung sells one appliance in several forms, and the same behavior points at different things on each of them. A built-in side-by-side and an integrated column are not the same service situation, and a dual-fuel range and an induction range fail in different halves. - **4-Door Flex and FlexZone** — The compartment has a setting that decides whether it freezes at all, and it is changed by accident more often than anything else in the kitchen. - **Bottom and top freezer** — One cooling system serves both compartments, so check whether the fresh-food side is also off before assuming the freezer. - **Convertible upright** — Samsung's standalone freezer. It is the only one of the three that is a freezer and nothing else, and it has its own setting to check. ### Why there is no code list on this page Samsung publishes no error codes for freezers. The one freezer-related code that exists, 21E for the freezer fan, is printed on the refrigerator table because that is where Samsung puts it. Rather than borrow a table from another appliance or another maker, this page carries the diagnosis instead — which is what the appliance actually gives you to work with. ### The convertible trap Samsung sells more convertible compartments than anyone else in this fleet, and every one of them can be told to stop freezing. It is a feature, it is on the panel, and it is the reason we ask what kind of cabinet you have before we ask anything else. A convertible compartment set to refrigerate Free, common, and the first thing we ask about on a Flex cabinet. The evaporator fan Samsung's 21E, and usually ice on the fan rather than a dead motor. Frost on the evaporator Airflow falls away gradually; the temperature follows. A door that is not sealing A freezer door that is held open a few millimeters by a basket will never hold temperature. Read the setting on any convertible compartment Freeze or refrigerate. It is on the panel and it takes ten seconds. Measure it with a thermometer Between packages, not against the wall, and after an hour. A freezer should sit around 0°F. Check the door closes and stays closed A drawer overfilled at the back holds a freezer door open a fraction, all day. Look for frost patterns Frost on everything is a door or a seal. Frost only at the back is the evaporator. Soft ice cream, and everything else on its way What it usually means A FlexZone or 4-Door Flex compartment may simply be set to refrigerate Samsung publishes no freezer codes — the symptom is the diagnosis Airflow and door seal before anything expensive Check the setting before anything else On any convertible compartment, look at what it has been told to be.

On a cabinet where one system serves both, that is unusual and specific — it usually means the cold is being made and diverted, or that a convertible compartment has been reset. On a standalone upright it is simply the freezer. ### How cold should it actually be? Around 0°F for a freezer and about 37°F for the fresh-food side. Measure it rather than reading the panel — the panel is one of the things being tested. --- **[Read full article: Freezer not freezing](https://samsungmiami.support/symptoms/freezer-not-freezing/)**
