Thermador Refrigerator Freedom Column Self-Test Error Message

What Self-Test means

Starting the built-in check on an 800-era IF column makes the display cycle through several messages. If all is well, the set temperature comes back. If the control spots a problem, the ALARM symbol lights up along with an error message; Thermador's example is a sensor error. The test points toward a part, but it cannot repair anything on its own.

Usual causes of Self-Test

A temperature sensor whose reading is out of range
Some other monitored part that the control reported during the check

✓ A safe check worth trying

1. Turn the column off and let it rest 5 minutes. 2. Power it on, keeping the door shut. 3. Press and hold SETUP plus ALARM OFF for 5 seconds. 4. When the sequence ends, write down any message left on the display.

! Why you should stop here

Thermador's direction is to hand the message to a servicer, since the check only identifies the area involved.
Sensors sit inside the liner or behind covers, so testing and replacing them is not a casual task.

Taking off a panel yourself does not by default void a manufacturer warranty, yet it can lead to accidental damage, and some manufacturers attach their own service terms. Read your warranty paperwork, or ask us, before you decide.

Self-TestSelf-Test questions

Does the food have to come out first?

No. The check only requires that the door remain closed, and afterward the column returns to its set temperature, so everything can stay inside during the run.

My settings vanished after I held the buttons. What happened?

A shorter press of the same two buttons, 3 seconds, resets the column to factory values. Hold them for the full 5 seconds right after powering on.

What do I do with the final message?

Record it word for word and give it to the technician. It tells them which sensor or part to test first, saving time on the visit.
