What AL1
actually means.
AL1 uses the same margin as AH1 on each CellarCool series, just below the setpoint instead of above. CellarCool's first check is whether the unit is still cooling: if the snowflake is lit, the unit is overshooting; if not, the cellar is losing heat to a cold space and needs warming from outside the unit.

What to do when AL1 shows on the wine cellar cooling unitKind of codeTemperature 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 toCellar 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 asWine Cellar Too Cold
A wine cellar too cold feels like stepping into a walk-in: the thermometer sits in the 40s, bottles come out beaded with water, and the unit keeps running long after the room should have been satisfied.

Before you book,
in this order.
Each step comes from CellarCool's own guidance for AL1 on its wine cellar cooling units. Follow it to the end: the last card says whether this is a visit.
Look for the snowflake on the display; if it is lit while the cellar is already cold, switch the unit off and book a visit.
If the unit is idle, warm the room gently until the wine returns to the setpoint.
Check the probe against a known thermometer; CellarCool's digital controller manuals include a probe calibration check in the user menu.

What not to do
AL1 alone does not mean refrigerant or compressor trouble. In winter it is often just the cellar's surroundings.

Ducted cellar cooling unit
A self-contained cooling unit placed outside the cellar, in a mechanical room, attic or basement, that sends chilled air in and takes return air back through insulated ducts.
Split-system cellar cooling
An evaporator inside or beside the cellar and a condensing unit outside or in another room, joined by an insulated copper line set and charged on site.

Still showing AL1?
When you book, type the code or the blink count as the controller shows it, add the full model number, and say what the thermometer in the cellar reads now — that gives the technician a head start.
