While you wait for the technician — 3 steps for Thermador
Silence the Alarm
Press the Alarm button on the top panel to stop the beeping. The alarm triggered because the internal temperature rose above the set point — silencing it doesn't affect the underlying problem.
Listen to the compressor
Is there a clicking sound every 5 minutes? That means the compressor is trying to start and can't — the inverter board or start circuit has failed. No clicking at all usually means the control board isn't sending the run signal.
Keep the doors closed
Thermador columns have excellent thermal insulation. Food stays safe for 10–12 hours if you don't open the doors unnecessarily.

Thermador Technician · Orange
Thermador built-ins — especially Freedom Collection — are built on the same BSH architecture as premium Bosch models, with two independent circuits: a separate evaporator and, on some configurations, a separate compressor for each column.
That independence is actually useful when diagnosing: if one column is warm and the other is fine, the problem is isolated to that column's circuit. The most common failure is the inverter board that drives the compressor. A power surge burns it out; the display and interior lights stay on, but the compressor never starts.
The second common cause is a frozen evaporator from a defrost system failure. On T-series models with a TFT touchscreen, also note: a brief power outage can reset temperature settings — the unit looks broken but just needs to be reconfigured. I run a full diagnostic scan on arrival to separate these cases quickly.
Why your Thermador isn't cooling — 4 causes
Premium built-in appliance repair.
1. Inverter board — 40%
Clicking but no compressor hum. Temperature rising in one column (or both). The inverter board that drives the compressor has burned out — typically from a voltage spike. Requires board replacement.
2. Defrost system (Defrost Heater) — 25%
Freezer column cold, refrigerator column warm. The evaporator is iced over, blocking airflow. Usually a burned defrost heater or failed NTC sensor. Most common on T36/T30 Freedom models between years 7–10.
3. Evaporator fan — 20%
Compressor runs normally but air doesn't circulate inside the column. The fan motor in that cabinet has burned out.
4. Main control board — 15%
Fridge completely unresponsive (though interior light may work), or display shows E-series errors. Control board has failed. Also check: after a power outage, T-series TFT models may reset temperature targets — reconfiguring settings sometimes resolves what looks like a failure.
Thermador not-cooling repair cost
Fixed labor rates. We use genuine Thermador / BSH OEM parts.
| What broke | Labor (fixed) | OEM part | Total |
|---|---|---|---|
| Evaporator fan replacement | $120–$180 | $100–$180 | $250–$380 |
| Defrost heater / sensor replacement | $120–$180 | $80–$150 | $230–$350 |
