On Marvel Professional wine units, HH is the high temperature notice. It appears when a compartment has been warmer than the control setting for an extended time. Marvel’s guide gives no owner steps beyond contacting service, so the first checks are the door, the grille and the room. Marvel wine cooler display What to do when HH 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 that the door closes and seals and that nothing blocks the front grille. If it comes back, it needs a visit. ### Which zone is warm when my Marvel dual-zone shows HH? The guide does not tie HH to a zone. Measure both with a thermometer; the upper zone is the colder one on the MPWD424. ### Can a warm room cause HH on a Marvel? It can add to it. Marvel’s unit has to push heat out through the front grille, so a hot room or a blocked grille makes the job harder. ### Should I clear HH by switching the unit off and on? That can reset the display, but it hides the warning. Find out why the zone is warm before relying on it again. --- **[Read on the site: Marvel HH: the wine compartment is running warm](https://winecoolerrepair.center/error-codes/marvel-hh/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
