HH on a Viking FWUI undercounter unit means one compartment has sat above its set point for a long stretch. Viking’s manual stops at telling you to reach service, so the only checks worth making yourself are the door and the grille at the toe kick. Viking 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 Viking Viking wine coolers serviced where they stand, when the cabinet warms up, stays dark or keeps cycling. ### Source Viking FWUI5242G Install / Use & Care manual (Professional undercounter wine unit) Viking Professional undercounter wine units FWUI5152G (single zone) and FWUI5242G (dual zone), with the touch control. ## Before you book, in this order.

Close the door firmly and clear anything leaning against the toe-kick grille. If it comes back, it needs a visit. ### Why does my Viking undercounter show HH but the column in my kitchen shows words? They use different controls. The Professional undercounter uses short codes such as HH; the 7 Series column writes out messages. ### Can a dirty condenser cause HH on a Viking undercounter? It can. These units breathe through the toe kick, so lint and pet hair there make the compressor struggle. ### Is HH urgent? Treat it as urgent if the wine is warming. Move your best bottles and book a visit. --- **[Read on the site: Viking HH: the undercounter wine compartment is warm](https://winecoolerrepair.center/error-codes/viking-hh/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
