My Thermador refrigerator is not cooling but the lights and display work. Why?

Thermador's use and care guides list demo mode first. In demo mode the cooling is switched off and everything else works. Switch it off in the settings menu, using the steps in your model's guide. If demo mode is off and it still won't cool, book a diagnosis.

What does a D or E message on a Thermador refrigerator mean?

Thermador's guide says the electronics detected a fault. Its owner step is to switch the appliance off, disconnect the power by unplugging it or switching off the breaker, and reconnect after 5 minutes. If the message is still there, book service. Write the message down before you reset anything.

What should I do with the food if the refrigerator warms up?

Thermador's guide covers this for a power failure: open the appliance as little as possible, and throw out frozen food that has thawed and is warmer than 41°F (5°C). Slightly thawed frozen food can be cooked, then eaten or frozen again.

Is my Thermador refrigerator still under warranty?

Check your purchase date against Thermador's warranty for your model. If it is still covered, call Thermador first so its own service handles it. Out of warranty, we repair Thermador refrigerators as an independent service, not a dealer. The $99 diagnostic is credited toward the repair.

Why this happens

What we look for first.

Demo mode is switched on. Thermador lists this first when the refrigerator is not cooling but the display and lights work. In demo mode the cooling is switched off and everything else keeps running, so do not store food in it. On the T36IT100NP the setting is under Service, Advanced Service, Demo Mode. On the columns it is in the appliance settings menu. Your model's guide has the exact steps.
Ventilation openings are covered. When the refrigeration unit runs more often and for longer, Thermador's guides say to remove anything in front of the external ventilation openings. The column guide also says to vacuum the ventilation openings once a year.
Heat around the cabinet. Thermador says to keep the appliance as far as possible from heating elements, cookers and other heat sources, and out of long direct sunlight. A built-in can't move, but if a range sits close by or sun hits it for hours, tell us when you book.
Doors opened often or warm food loaded. Thermador's guides say to open the doors only as briefly as needed and to let hot food and drinks cool before they go in. Before loading a large amount of fresh food, the column guide says to switch on super cooling.
Temperature far from the setting. Thermador's step is to switch the appliance off for about 5 minutes and back on. If it is too warm, check again after a couple of hours. If it is still far off after that, book a diagnosis.
A message with D or E on the display. Thermador says this means the electronics detected a fault. Its owner step is to switch the appliance off, disconnect the power by unplugging it or switching off the breaker, and reconnect after 5 minutes. If the message comes back, write it down and book service.

How we diagnose and fix it

The walk-in workflow.

01
We start at the display: the set temperatures, any alarm or message with a D or E, and whether demo mode is on.
02
We check what Thermador's guides ask of the installation: clear ventilation openings, no heat source or long direct sun on the cabinet, and doors that close.
03
We measure the temperature in each compartment and compare it with the setting.
04
If the cause is inside the refrigerator, we test the part we suspect before we name it.
05
You get one written price for the repair before any work starts.

San Mateo is a downtown restaurant town, with density along 25th Avenue and B Street that keeps commercial refrigeration steady, reach-ins, ice machines, and prep coolers.
