The four SmartThings alarms Dacor refrigeration appliances use are Self Check, Abnormally High Temperature, Door Open, and Filter Replacement, and this exact set — no more, no fewer — covers refrigerators, freezers, column refrigeration, and wine refrigeration alike, confirmed independently across four separate official manuals.
Self Check
Self Check is the app noticing something abnormal about the unit’s own operation. It is documented as a general-purpose flag rather than a specific failure description, meant to draw attention early rather than to demand immediate action. Treat it as a prompt to check the unit, not as confirmation that a part has failed.
Abnormally High Temperature
This is the one alarm across all four refrigeration types worth treating with real urgency, since it means the cabinet has drifted warmer than its expected range for long enough that the app considers it worth a push notification. On a wine column, this same alarm covers the cellar rather than a kitchen refrigerator, but the meaning and urgency are identical. Ignoring this alarm risks the contents, whether that is groceries, frozen food, or wine.
Door Open (Door Opening on the wine column)
This fires when a door has sat open longer than a set threshold — frequently nothing more than a grocery unload or a bottle being selected, not necessarily a seal failure. A persistent Door Open alert despite the door appearing closed is worth checking against panel alignment on panel-ready installations, or against anything in a door bin propping the seal open slightly.
Filter Replacement (Deodorizer Filter Replacement on the wine column)
This is a maintenance reminder tied to the water or deodorizer filter’s service interval, not a problem at all. It will keep appearing until the physical filter is replaced and the reminder cleared, regardless of how well the unit is otherwise cooling.
What these four are not
None of the four alarms is an alphanumeric code, and no Dacor refrigeration manual reviewed in this research shows a code like 5E, 21E, TEMP-HI, or FAN-FAIL anywhere in its text. Sites listing such codes for Dacor refrigeration are describing something that does not appear in Dacor’s own documentation, and this holds consistently across all four refrigeration appliance types.
Reading the alarms correctly across appliance types
The same four names apply everywhere, but context differs: a Door Open alert on a paired column installation is worth checking against panel-front alignment specifically, while the same alert on a French-door refrigerator points more often at a bin or bag caught in the seal. An app showing any refrigeration unit “offline” always means Wi-Fi connectivity, never a cooling problem, regardless of which of the four appliance types is involved.
Where to go from here
Our refrigerator, column refrigeration, and wine refrigeration pages cover each type’s current models, and reading the exact alarm wording before booking a visit helps a technician prepare in advance. Dacor’s own site lists which current refrigeration models include SmartThings connectivity.
