Check that the door is closed and not held open by a rack or bottle. If it comes back, it needs a visit. ### At what temperature does a True wine unit sound its high temperature alarm? For True single and dual zone wine units, the manual gives 70°F held for more than an hour. ### Can I turn off the high temperature alarm on a True wine unit? On True undercounter units the same key that turns on the door alarm also turns on the high temperature alarm. Leaving both on is the safer choice for a collection. ### My True column shows HIGH TEMP after I loaded a case of wine. Is that normal? Loading many room-temperature bottles can warm a zone for a while. Give it several hours, and book a visit if the alert stays. --- **[Read on the site: True HIGH TEMP: the wine column is warmer than it should be](https://winecoolerrepair.center/error-codes/true-high-temp/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
