Thermador SuperCool is the name our model pages use for rapid chilling on some Thermador refrigerators. The Freedom T36FT810NS page describes a 36-inch French door refrigerator with dual compressors, ThermaFresh drawers, SuperCool rapid chilling and a counter-depth profile, and the Masterpiece T30BB920SS and T36BB925SS bottom-freezer pages also list SuperCool. Our pages do not describe how SuperCool works inside, so this glossary explains the general idea of a rapid-chill function, with the usual caution that what it does on your exact model, and when it stops, is in your owner’s manual.
What is Thermador SuperCool?
It is a rapid-chill function for the fresh food compartment. Our T36FT810NS page uses the words SuperCool rapid chilling, and that is the whole of what our pages say about it. In general, a function like this makes the refrigerator cool harder than usual for a while, so that a big load of warm items, such as groceries just back from the store, comes down to temperature sooner.
Our Freedom column guide describes it the same way: it drops the temperature temporarily when you load a large grocery haul, and our power outage guide suggests using it, if your refrigerator has it, to speed recovery. It is a temporary boost, not a setting to leave on. Whether SuperCool switches itself off, how you start it and how it shows that it is running are details of your model, so check the manual.
Which Thermador refrigerators list SuperCool?
On our site, the T36FT810NS Freedom 36-inch French door refrigerator and the Masterpiece bottom-freezer models T30BB920SS and T36BB925SS. The Masterpiece pages describe dual compressors, a glass-on-stainless door and a counter-depth profile for flush installation. Other Thermador refrigerator pages describe different features, such as column designs, and their descriptions do not mention SuperCool, which is not proof that a refrigerator lacks it. The model’s manual or spec sheet confirms.
When is SuperCool useful?
When the refrigerator has taken in a lot of warm food at once. That is the case after a big shop, after a party when you are refilling the shelves or when the door has been open for a long time. In those moments the compartment warms up and takes time to recover, and a rapid-chill function shortens that time.
It is not a fix for a refrigerator that cannot hold its temperature. If the compartment is warm all the time, the cause is something else, and our Thermador refrigerator temperature problems guide shows what to check. Start the function, close the door and leave it alone. Opening the door while it runs undoes the chilling.

How is SuperCool different from SuperFreeze and ThermaFresh?
They are three different functions. SuperCool is the rapid chill for the refrigerator compartment. SuperFreeze is a freezer function; our SuperFreeze explainer covers it. ThermaFresh is a controlled storage drawer with its own temperature and humidity; our ThermaFresh explainer describes it. The names sound alike, but they act on different parts of the refrigerator.
What should you keep in mind while it runs?
Keep the door closed as much as possible and do not overfill the compartment, so air can still circulate. Your manual may say more about food placement while the function is on. Our refrigerator organization guide helps you arrange the shelves so air can flow.
If you are not sure the function has ended, look at the display or the manual for how it signals. If the compartment seems colder than you set it, check the setting and the manual.
What should you look for in the manual?
Four things settle most questions. First, how to start the function, whether from a touch panel, a button or the Home Connect app that our pages list on these models. Second, how the display shows that it is running. Third, whether the refrigerator ends it on its own and returns to your normal setting, or whether you have to switch it off. Fourth, any note about the freezer or about food placement while the function is on.
Write down the answers, or stick a note inside the cabinet door, because a function you rarely use is easy to forget. If your manual and our pages ever differ, trust the manual for your exact model.
When does SuperCool point to a problem?
If the compartment is not cooling even with the function on, if the compressor never stops, if food freezes in the compartment or if water collects inside, the function is not the issue. Check that the door closes properly, then see our guide to refrigerator troubleshooting. Do not remove back panels or touch the cooling system. If water reaches an outlet or the cord, switch off the breaker at the panel while standing on a dry floor, and do not pull the plug out of a wet outlet.
