Symptom
Thermador wine column not holding temperature
One zone drifting while the other holds, condensation on the glass, or a cabinet that has started running constantly. With wine, steadiness matters more than the exact number.

Five ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
The glass door and its seal
Heavier than it looks and easy to leave not quite closed. Condensation on the inside of the glass is usually this before it is anything else.

Anti-condensation heating in the frame
A glass door has heating in its frame to stop it misting. When that fails, the cabinet cools fine and the door fogs.

A zone damper or fan
What separates two zones in one cabinet. It is the usual answer when one side is right and the other is not.

The room around it
A cabinet in an unconditioned space in August is being asked to do more than it was designed for, and it will run constantly doing it.
-
The cooling system
Thermoelectric and compressor cabinets fail differently and cost differently. Which one you have is the first thing we establish.

01
Note which zone and by how much
Both numbers, and whether they are steady or moving. Steady and slightly off is a different problem from swinging.
-
02
Check the door seals and the closing
Glass doors are heavy and often close on a soft magnet rather than a latch. A bottle rack pushed out slightly is enough to hold one open.
-
03
Look at the room
Ambient temperature and humidity, particularly for a cabinet in a garage, a butler pantry or an open-plan space.
-
04
Watch for vibration
A cabinet that has started to buzz or hum is worth mentioning: vibration matters to wine and it is a real symptom rather than an annoyance.
How it shows up
What people describe when they call
Two shortcuts
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem, and the model number says which parts to bring. Either one shortens the visit; both together usually settle it.

About Thermador wine column not holding temperature
Which zone, and is it drifting or swinging
A dual-zone cabinet where one side holds and the other does not points at that zone — its damper, fan or sensor — rather than at the cooling system. Both zones drifting together is a different and larger conversation.
Storage, not refrigeration
A wine column holds a steady temperature in two zones without vibration and without light, which is a different job from keeping food cold. That means more components — dampers, zone sensors, heating in a glass door frame — and it means the useful question is stability rather than whether the number is exactly right.
What we look at, in order
- Which zone, and whether it is drifting or swinging
- The door: seal, closing, and the heating in the frame if the glass is fogging
- The room, which on a cabinet outside conditioned space is often most of the answer
- The cooling system last, and priced according to whether it is thermoelectric or a compressor

Before you book
Questions about thermador wine column not holding temperature
Is a couple of degrees off actually a problem?
Less than a temperature that moves. Wine tolerates being slightly warm far better than being cycled up and down, so the question we ask first is whether it is steady — not whether the display matches the ideal.
There is condensation on the inside of the glass.
Usually the door or the humidity rather than the cooling: the seal, the door not sitting square, or the anti-condensation heating in the frame. In a Miami summer, a cabinet in an unconditioned room will do it regardless of what is wrong or right.
One zone works and the other does not.
That is useful. It generally rules out the compressor and points at the damper, the fan or the sensor for that zone — and the wine in the working half is safe while you decide.
