What to do when 40 1 09 shows on the wine coolerKind of codeTemperature and alarms
The cooler read a zone well away from its setting and raised an alarm, sometimes showing the warmest figure it reached while the house was empty. The reason may be as small as a door left resting on a bottle neck or a long outage, or as serious as cooling that has stopped. Keep the glass door shut and feel a bottle in the middle of the rack before doing anything else; the alarm is a warning about the wine, not a diagnosis.
