How it shows up ## What people describe when they call - “Cabinet warmer than its setting” - “Compressor running and never resting” - “An alarm symbol on the display” 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.

[ All models ](https://thermadormiami.support/models/) In more detail ## About Thermador refrigerator not cooling ### There is no code, and here is what to read instead Press the ALARM button on a column that has alarmed: it stops the signal and shows the highest temperature the cabinet reached, once, for a few seconds. Read that before you clear anything — it is the difference between “it feels warm” and a measurement. ### Cheapest causes first, and they are the common ones Door seal, condenser, airflow, fans. Every one of those produces a cabinet that will not hold temperature, all of them are ordinary work, and all of them are checked before anybody says the words “sealed system”. That order is not politeness — it is the only way to arrive at an expensive diagnosis you can trust. ### The self-test is yours to run Switch the column off, wait five minutes, switch it on with the door closed, then hold SETUP and ALARM OFF together for five seconds. It steps through its diagnostics and finishes either by showing the set temperature — nothing found — or with an alarm symbol and a message. Either outcome is worth having before a technician arrives. This article is based on: - Official manufacturer documentation - Internal repair procedures - Technician repair history - Company quality standards Before you book ## Questions about thermador refrigerator not cooling Because this make does not publish any for its refrigeration — the pages where such codes would live do not exist. What the column gives you instead is an alarm, a symbol, and a self-test, and those are what a diagnosis is built from here. On separate columns those are two appliances and it tells you little. Within one cabinet it points at airflow or a damper rather than at the cooling system, which is the cheaper end. Hours, not minutes, especially in a Miami summer with a full cabinet. An alarm that clears on its own as it pulls back down is a warm load, not a repair.
