What DO2
actually means.
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.

What to do when DO2 shows on the freezerKind of codeMode, 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 toNo repair
Close the door or drawer and make sure it seals.
Shows up asFreezer 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.

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.
Close the door or drawer and make sure it seals.
Start a manual evaporator defrost from the display; it will not start if the evaporator is too warm or Quick Cool is running.
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.

Still showing DO2?
Book with the code or the alarm pattern written exactly as the freezer shows it, the full model number, and whether the food is still frozen hard — when there is a code, that is where the diagnosis starts.
