AL flashes in turn with the temperature once the cellar climbs above the alarm point stored in the Sentry III. The unit keeps cooling during the alarm; only if the room keeps warming to 75°F does the overheat protection step in. Breezaire wine cellar cooling unit display What to do when AL shows on the wine cellar cooling unit ### Kind of code Temperature and alarms The controller saw the cellar go past a high or low limit and raised an alarm, sometimes holding the worst reading it logged while the house was empty. The reason can be as small as the cellar door left ajar after a tasting or a long outage, a room gaining heat from new lights or a sunny glass wall, or as serious as cooling that has stopped. Keep the door shut and read a thermometer on a middle rack before touching anything; the alarm is a warning about the collection, not yet a diagnosis. ### Usually leads to Cellar cooling load and room check Measuring the cellar as the cooling unit sees it: insulation, vapor barrier, door, glass and the heat load, to show whether the unit can ever keep up. ### Shows up as Cellar Cooling Unit Error Code A cellar cooling unit error code appears as letters or digits on the controller, a flashing reading, a blinking light on the unit, or an alarm tone, sometimes while the cellar still holds its temperature. ### Make Breezaire Visits to cellars cooled by a Breezaire unit, starting with a thermometer among the racks and a hand at the exhaust grille. ### Source Breezaire Sentry III Plus Controller owner's manual Sentry III and Sentry III Plus controllers on WKL through-the-wall units and WKSL split systems. Older WKS splits built before mid-2010 used a manual thermostat and show none of these codes. ## Before you book, in this order. Each step comes from Breezaire's own guidance for AL on its wine cellar cooling units. Follow it to the end: the last card says whether this is a visit. 01 Keep the cellar door shut and check the room with a separate thermometer at bottle height. 02 Make sure the alarm point has not been set lower than you meant; it is in the settings reached by holding SET for more than 5 seconds. 03 Clear anything in front of the exhaust grille and look at the condenser coil for dust. 04 If the room keeps rising toward 70°F, move the most valuable bottles and book a visit. ### Still there? It usually turns into [cellar cooling load and room check](https://winecellarrepair.center/services/cellar-cooling-load-and-room-check/). Book with the code and the model number. ### What not to do AL is a warning, not a shutdown, and the unit is still trying to cool. If the display is flashing OH instead, the unit has switched itself off. ## What you may notice with it. The wine cellar cooling unit problems AL tends to arrive with.

Keep the cellar door shut and check the room with a separate thermometer at bottle height. If it comes back, it needs a visit. ### Can I change the temperature at which a Breezaire shows AL? Yes. Hold SET for more than 5 seconds, press SET to step through until the display flashes AL, then adjust with WARMER or COOLER. The factory value is 62°F. ### Why does my Breezaire show AL after the door was left open? An open door lets warm air in faster than the unit can remove it, so the room can pass the alarm point quickly. If the display settles back to a plain temperature within a few hours of closing the door, the unit is keeping up. ### Does AL stop my Breezaire from cooling? No, Breezaire says the unit keeps running in the alarm state. It only shuts down if the cellar reaches 75°F, which the display then reports as OH. --- **[Read on the site: Breezaire AL: the cellar is above its alarm point](https://winecellarrepair.center/error-codes/breezaire-al/)** **[Book a visit with WineCellarRepair.center](https://winecellarrepair.center/schedule/)**
