Close the door named by the L or R and make sure nothing is holding it open. If it comes back, it needs a visit. ### What does the L or R before Door Open 5M mean? On a dual-zone 3000 Series unit, L is the left door and R the right. Single-zone models show the alert without a letter. ### The alert shows even when both doors are shut. Why? U-Line’s service table points at the door closing, the cable arm and its magnet, and the reed switch. One of those is telling the control the door is open. ### Will Door Open 5M lead to a warm alarm? If the door stays open long enough, yes. Several hours with that side warm can be followed by Temp Hi 6H+. --- **[Read on the site: U-Line Door Open 5M: a 3000 Series wine door was left open](https://winecoolerrepair.center/error-codes/u-line-door-open-5m/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
