DO2 is the G5 long-period door alarm. Because a long-open door lets humid room air build frost on the evaporator, Perlick asks you to close the door and then start a defrost cycle. Perlick wine cooler display What to do when DO2 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).

Close the door and confirm it seals. If it comes back, it needs a visit. ### What is the defrost step after DO2 for on a Perlick? Room air carries moisture that freezes on the cold coil. Running a defrost melts that ice while it is still thin, so air keeps flowing. ### Can DO2 lead to water on the floor? Extra frost melts during defrost and drains away. If the drain is blocked, water can end up outside, so wipe it up and keep clear of the outlet. ### The door was only open briefly but DO2 showed. Why? The door switch may not be registering the door as closed. The diagnostic window shows what the switch reports. --- **[Read on the site: Perlick DO2: the wine reserve door was open for a long time](https://winecoolerrepair.center/error-codes/perlick-do2/)** **[Book a visit with WineCoolerRepair.center](https://winecoolerrepair.center/schedule/)**
