The RF23DB9900QD is Samsung’s 23 cu. ft. 4-Door Flex refrigerator, described on its samsung.com page as Bespoke AI 4-Door Flex™ Family Hub™ 32″ AI Vision & Auto Open Door | 23 cu.ft.. Because the RF23DB9900QD carries a Family Hub screen, it can report its own 41 or 42 codes when the screen and the main control stop talking, and a frozen or rebooting screen on this model is a control problem rather than a cooling one.
With the RF23DB9900QD switched off at the breaker, the rear evaporator cover comes off and the fan, the defrost heater and its sensor are measured before any part is ordered; a sealed-system problem is confirmed by pressure and temperature readings, never assumed from a warm cabinet.
