What do means

On DCS RF24RE3 and RF24LE3 outdoor refrigerators, and on RF24TR1, RF24TL1, RF24BTR1 and RF24BTL1 beer dispensers, do is the door ajar alarm. If the door stays open for more than five minutes, the unit beeps at one-second intervals, the display flashes do and the Alarm LED lights. Everything stops as soon as the door is shut, so this is a reminder rather than a failing part.

Common causes of do

A door left open for more than five minutes
A door that did not latch because of a gasket or an item sticking out
Contents or a shelf that holds the door slightly ajar

✓ One safe check you can try

1. Close the door firmly. 2. Press any key to mute the beep while you sort things out. 3. Check that bottles, cans or a shelf are not holding the door open. 4. Look along the door edge for anything caught in the gasket. 5. Wait a minute to confirm do has cleared.

! Why to stop there

If do keeps returning with the door fully latched, we check how the door closes and whether the unit senses it correctly.
A door that will not seal can also let the cabinet warm up, so we look at temperature as well.
Parts for these units are usually easy to confirm, and we give you a written price before work.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Close the door, and the alarm stops on its own. Pressing any key mutes the sound while you fix the cause, although the display keeps showing do until the door is shut.
