What Flashing temperature with (!) below the low limit
actually means.
The low temperature alarm flashes the reading with the (!) symbol when the cellar falls below setting 2, which is 50°F from the factory. It clears when the temperature rises above that setting. A setpoint set too low, a cold surrounding space in winter or a unit that keeps cooling past its setpoint can all cause it.

What to do when Flashing temperature with (!) below the low limit 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 Wine Guardian's own guidance for Flashing temperature with (!) below the low limit on its wine cellar cooling units. Follow it to the end: the last card says whether this is a visit.
Check the setpoint on the remote and raise it if it was lowered by mistake.
If your remote shows a heat symbol, check which mode the unit is in; if it only cools, the room may simply be losing heat to a cold space.
If the setpoint is right and the unit keeps cooling anyway, switch it off and book a visit.

What not to do
A low temperature alarm is not a sign of a refrigerant problem by itself. It is often seasonal, when the space around the cellar gets cold.
