Quick answer
For a Thermador refrigerator that is not cooling, check the display, compartment temperatures, door closure, airflow, and household power from outside. Protect perishable food and arrange qualified service if the appliance remains warm or shows a fault.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Check the display, interior lights, and compartment temperature from outside, noting any warning or recent power interruption.
Expected result: The display is blank, powered but warm, or shows a warning.
Next step: Complete one safe power check, then arrange service for persistent warmth or a warning.
Why this matters
Why: This separates a supply or control symptom from a cooling-only symptom.
-
Check 2
Confirm doors close fully, gaskets are clean, and food is not blocking visible air outlets.
Expected result: A door or airflow obstruction is present, or these checks are normal.
Next step: Remove only loose obstructions and monitor briefly; protect food and arrange service if warm.
Why this matters
Why: A closure or loading condition can reduce cooling performance; normal checks require model-specific diagnosis.
-
Check 3
Check the accessible outlet and breaker once when safe, without repeatedly resetting protection.
Expected result: The outlet is dead, the breaker is open, or power is stable.
Next step: Use a qualified electrician for a dead outlet. Leave the appliance off if protection trips again.
Why this matters
Why: Thermador support distinguishes household power interruptions from an appliance fault.
-
Check 4
Record whether the compressor or fan sound changes and whether the freezer and refrigerator compartments differ.
Expected result: One compartment is affected, both are warm, or unusual noise or heat is present.
Next step: Protect perishables and arrange qualified Thermador service.
Why this matters
Why: The pattern helps service triage but does not identify a part for replacement.

-
PATH 01Next step
What you see
Not cooling is linked to an accessible obstruction, setting, or supply issue
Do this next
Correct only the documented condition and monitor once.
Why this path and its safety boundary
Why it matters: The symptom may have an external explanation that can be corrected under the exact manual.
-
PATH 02Next step
What you see
The refrigerator remains not cooling after safe external checks
Do this next
Arrange qualified Thermador service.
Why this path and its safety boundary
Why it matters: The assigned symptom is not resolved by an accessible condition and needs model-specific diagnosis.
-
PATH 03Next step
What you see
The symptom includes heat, smoke, burning odor, water damage, exposed wiring, or a repeat breaker trip
Do this next
Leave the appliance isolated when safe and obtain qualified service.
Why this path and its safety boundary
Why it matters: The condition is unsafe to continue testing.
Helpful context
Understand the symptom
The useful decision for a refrigerator that is not cooling is to separate an accessible loading, setting, or supply condition from a symptom that needs model-specific service. Observe the result of each check before taking the next step.
When checks do not resolve it
Need a professional?
Stop troubleshooting and arrange qualified Thermador service if the Thermador refrigerator remains not cooling after the safe external checks, if a control is damaged, or if a breaker trips again. Do not remove covers or work on energized, gas, sealed, or refrigerant components.
