Thermador refrigerator error code: display goes dark
Thermador error code, the kind with no number: display goes dark — the supply has dropped below the minimum the column will run on, so it has shut its controls down. What it covers, what to check first, and what it does not tell you, on built-in refrigerators & columns and freezer columns.

What we can confirm
Code Display goes dark, 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.

The symptom this code usually arrives with
A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.

No code — read the alarm Refrigerator not cooling
A column that is warmer than it should be, running constantly, or alarming. This make publishes no refrigeration error codes at all, so what the cabinet signals is the diagnosis.
- Cabinet warmer than its setting
- Compressor running and never resting
- An alarm symbol on the display

About Thermador refrigerator error code: display goes dark
What this one means
The supply has dropped below the minimum the column will run on, so it has shut its controls down. 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:
- The display light going out, with no button responding
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 supply problem in the house rather than in the appliance
- A shared circuit under load
- The neighborhood supply during a storm or a brownout
What to try yourself
- Check whether other things on the same circuit are behaving oddly, and whether a breaker has tripped
- Wait — the warning clears by itself once the voltage comes back
Then what
South Florida gives this one more often than most places, and it is the one condition here where the answer may be the power company rather than us. If the display stays dark on a circuit that is plainly healthy, then it is the column.
This one appears on built-in refrigerators & columns and freezer columns. The full list of codes has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
