Some Samsung smart fridges stopped working on Tuesday due to a firmware update.

Korean outlets were the first to report the problems, which affect Samsung’s Bespoke AI line of fridges. Star News Korea, per a Google-provided translation, said that most of the affected devices were four-door fridges from 2024 or later.

Affected fridges “suddenly lost power and stopped functioning immediately after” trying to issue a firmware update through SmartThings, Samsung’s smart home platform, per Star News Korea. The SmartThings app then showed the devices as offline. Some users said that their fridge’s internal display was stuck showing the message “Checking SmartThings app during update.”

There are numerous reports on Samsung’s Korean community forum detailing the problem. Some users claim that they have owned their affected fridge for just a year or less.

“[T]he refrigeration and refrigeration functions themselves did not work normally, so all the food in the refrigerator had to be disposed of,” one user wrote, per a translation.
