How the beverage center detects dr

A U-Line beverage center keeps track of whether its door is open or closed through a switch at the door frame. While the door is open, the control starts a timer. Nothing happens during a short pause, because loading and unloading drinks is normal. Once the door has been open for more than five minutes, the control decides that the pause has gone on too long and raises the alert.

The alert has two parts: the letters dr appear on the display, and a tone sounds so that someone nearby notices. The control does this because cold air keeps flowing out and warm room air flows in, which makes the cabinet work harder and lets the drinks warm up. As soon as the switch reports a closed door, the control drops the alert and the cooling system returns to holding the set temperature.

Why dr appears

• The door was left open or pushed shut only partway
• A bottle, case or shelf edge keeps the door from closing all the way
• A twisted or worn gasket stops the door from sitting flat
• The door switch does not report that the door has closed

Can you keep using the beverage center with dr?

Yes. Dr is a reminder, not a shutdown, so closing the door is the whole fix and the cabinet carries on cooling normally. Give it a few hours to pull back down to the set temperature before you judge how cold the drinks are. If dr appears over and over with the door properly shut, the door switch or gasket may be the cause, and the cabinet could be running with warm air getting in. In that case use a separate thermometer to keep an eye on the temperature until it is looked at.

What you can safely check

1. If the floor near the cabinet is wet, switch the unit off at the breaker before touching it; otherwise leave it running.
2. Push the door shut and see whether it stays closed by itself.
3. Pull back any bottles or cases that poke out past the front of the shelves.
4. Clean the door seal with a damp cloth and check it for creases or open spots.
5. Look at the feet and make sure the cabinet is level so the door does not swing open.
6. If dr comes back while the door is shut, call us.

What our technician does for dr

• Test the door switch to confirm it registers a closed door
• Check the gasket fit and the door alignment against the cabinet
• Confirm the cabinet pulls back down to its set temperature after the door closes

How to keep dr from coming back

• Keep bottles and cases well back from the front edge of each shelf so the door can close.
• Wipe the gasket now and then so spills and sticky residue do not hold the door off the cabinet.
• Check that the cabinet stays level, especially after moving it or loading heavy cases.
