What we can confirm

## Code Door alarm, from the manufacturer’s own documentation

This code has no number, because this equipment has no display to put one on. The appliance signals it instead — an alarm, a symbol or a pattern of lights — and what it means is recorded in the documentation that ships with it.

## About Thermador refrigerator error code: door alarm

### What this one means

The door has been open too long, or is not closed as far as the column believes it should be. This is a code without a number: the refrigeration columns have no display to put one on, so the appliance signals it instead. This make publishes no numeric codes for its refrigeration at all, and what this one means comes from the manufacturer’s own documentation rather than from us.

### How it shows on the display

There is no number to write down here, so this is what to look for:

- **A continuous tone with the door signal on the display**

### What sets it off

An alarm is deliberately broad — it tells you the cabinet noticed something, not which part is responsible. This one comes on for:

- A door held open while the kitchen is loaded
- A drawer or a bottle holding the door off its seal
- A gasket that has gone hard or torn
- A heavy paneled door out of adjustment on its hinges

### What to try yourself

- Close the door and watch the display — it should go out immediately
- Run a hand along the seal for a cold draught, and check a sheet of paper is gripped all the way round

### Then what

On a paneled column the door carries the weight of your cabinetry, and hinges are adjusted rather than replaced. A door alarm that keeps returning on a closed door is usually the seal or the adjustment, and both are ordinary work.
