What DO1
actually means.

DO1 is the G5 alarm for a door opening lasting a short period. Perlick’s only step is to close the door; the code is a reminder rather than a failure.

What to do when DO1 shows on the freezer

Kind 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 fully and check that nothing sticks out.

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 DO1 on its freezers. Follow it to the end: the last card says whether this is a visit.

01

Close the door or drawer fully and check that nothing sticks out.

02

On drawer models, check both drawers, since the control watches each one.

03

If DO1 appears with everything closed, have the door switches checked.

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

DO1 does not mean the freezer is warm. The longer version, DO2, is the one that asks for a defrost afterward.

Questions
about DO1.

Can I clear DO1 myself?
Close the door or drawer fully and check that nothing sticks out.
Why did my Perlick log DO1 when I was only loading food?
Loading with the drawer open counts as a door opening. DO1 is just the record of it.
Can a warped drawer front trigger Perlick DO1?
If the drawer does not close far enough to press the switch, yes. Check the drawer alignment and the panel fit.
Do I need to clear DO1 on a Perlick?
Closing the door is the action Perlick lists. You can review past entries in Alarm History.

Back to your everyday

Still showing DO1?

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.
