DO2 is the G5 alarm for a long door opening. Perlick asks you to close the door and start a defrost cycle, because warm, moist air that came in will have frozen onto the evaporator. Perlick freezer display What to do when DO2 shows on the freezer ### Kind of code Mode, not a failure A setting the freezer was put into, often by accident or by the store it came from, rather than a part that broke: a showroom or demo mode that lights the display while the compressor stays off, a fast freeze left running for days, a Sabbath setting that silences the alarms, a control lock, a door alarm reminding you the door stood open. Nothing has worn out, and the freezer's own buttons or manual put it back. ### Usually leads to No repair Close the door or drawer and make sure it seals. ### Shows up as Freezer Error Code A freezer error code appears on the display: letters and digits, a flashing temperature, or a warning symbol, sometimes with an alarm and sometimes with the freezer still running. ### Make Perlick Perlick freezers repaired in place, whether the trouble is soft food, a stubborn alarm or frost on the walls. ### Source Perlick G5 User Installation & Operation Manual, Form Z3023 (linked from the G5 Luxe 24-inch freezer drawers page) Perlick G5 undercounter models with the touch display, including the G5 Luxe 24-inch freezer drawers (URS24E61). The code appears in Alarm History, which keeps the last ten alarms with date and time. ## Before you book, in this order. Each step comes from Perlick's own guidance for DO2 on its freezers. Follow it to the end: the last card says whether this is a visit. 01 Close the door or drawer and make sure it seals. 02 Start a manual evaporator defrost from the display; it will not start if the evaporator is too warm or Quick Cool is running. 03 Check the food nearest the opening, and book a visit if the cabinet does not recover within a day. ### Cleared? The freezer is holding its temperature again and no part had to be replaced. If the same code comes back within a few days, or the packages start to soften again, book it as a fresh problem. ### What not to do DO2 is not a broken door switch if the door really was open. It is also not the high temperature alarm, though a long opening can bring on T1H as well. ## What you may notice with it. The freezer problems DO2 tends to arrive with. Answer these at the freezer before anyone is booked.

Close the door or drawer and make sure it seals. ### Why does Perlick want a defrost after DO2? Humid room air freezes onto the evaporator while the door is open. A defrost clears it before it blocks airflow. ### How do I start a defrost on a Perlick G5 freezer? Swipe to the standard defrost icon on the display, select it and confirm. Automatic defrost resumes afterward. ### My Perlick will not start the defrost after DO2. Why? Perlick says it will not start if the evaporator is too warm or Quick Cool is on. Wait for the unit to cool, or turn Quick Cool off, and try again. --- **[Read on the site: Perlick DO2: the door stayed open a long time, run a defrost](https://freezerrepair.center/error-codes/perlick-do2/)** **[Book a visit with FreezerRepair.center](https://freezerrepair.center/schedule/)**
