DO1 is the G5 short-period door alarm. Perlick’s only instruction is to close the door. It is an early nudge, and it can turn into DO2 if the door stays open. Perlick wine cooler display What to do when DO1 shows on the wine cooler ### Kind of code Door and seal The cooler noticed its door open for too long, or a switch that never reports it closing. Often a rack slid out a little too far holds the glass off the gasket, the cabinet has tipped forward off level, or a hinge has sagged under a heavy door; now and then the door switch itself has failed. Warm air getting in shows as fog on the glass and a zone that will not settle. ### Usually leads to Wine cooler glass door and gasket repair Replacing a torn or flattened gasket, resetting a door that no longer closes square, and repairing the glass door that keeps light, heat and humid air away from the bottles. ### 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 Perlick Perlick wine cooler repair for units under the counter or behind the bar that no longer keep a steady temperature. ### Source Perlick G5 User Installation & Operation Manual, Form Z3023 (linked from the G5 Luxe 24-inch wine reserve page) Perlick G5 Core and G5 Luxe wine reserves with the touch display, single-zone (URS15W, URS24W) and dual-zone (URS24D).

Push the door until it latches fully. If it comes back, it needs a visit. ### How can I check whether my Perlick thinks the door is open? The diagnostic window in the service menu shows the door switch as OPEN or CLOSED. If it reads OPEN with the door shut, the switch needs a look. ### Does DO1 stay in the alarm history? Yes. The G5 keeps the last ten alarms with a date and time stamp. ### Is DO1 the same as DO2? No. DO1 is the short-period alert; DO2 means the door was open long enough that Perlick asks you to run a defrost. --- **[Read on the site: Perlick DO1: the wine reserve door is open](https://winecoolerrepair.center/error-codes/perlick-do1/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
