LL is the low temperature notice on Marvel Professional wine units, the opposite of HH. The compartment has been colder than its setting for an extended time, which usually points at a control or sensor problem rather than something you can fix. Marvel wine cooler display What to do when LL shows on the wine cooler ### Kind of code Temperature 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. ### Usually leads to Wine cooler thermostat and sensor repair Testing and replacing the thermostat or the temperature sensors that tell a wine cooler when to cool, when the cabinet runs too cold, too warm or back and forth. ### Shows up as Wine Cooler Error Code A wine cooler error code appears as letters and digits on the display, a flashing temperature, dashes where a number should be or a blinking symbol, sometimes with an alarm tone and sometimes while the cabinet stays perfectly cool. ### Make Marvel Marvel wine coolers serviced where they are installed, from a warm cabinet to a door that no longer closes tight. ### Source Marvel MPWD424 User Guide (Professional dual-zone wine) Marvel Professional wine models with the touch control, such as the MPWD424 24-inch dual-zone unit. ## Before you book, in this order.

Check the zone settings. On the MPWD424 the lower zone cannot be set colder than the upper, and changing the upper can move the lower. If it comes back, it needs a visit. ### Why did my Marvel lower zone change when I adjusted the upper? Marvel links the two zones on the MPWD424. The lower zone cannot be colder than the upper, or more than 20 degrees above it. ### Is LL bad for wine? A few degrees cold only slows aging. Temperatures close to freezing can push corks, so act if it keeps dropping. ### Could LL be a sensor problem? Yes. A sensor reading warmer than the real air makes the control overcool. The technician tests it. --- **[Read on the site: Marvel LL: the wine compartment is running cold](https://winecoolerrepair.center/error-codes/marvel-ll/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
