How We Repair Your Thermador Range Hood
Range hoods and exhaust, ceiling, attic and whole-house fans move air with a motor and blower, controlled by switches, speed controls or sensors.
Every Thermador model has its own parts list, so we start with the model and serial number on the rating label. That tells us the correct parts and any known issues or service bulletins for your unit.

A failed bulb, socket or light switch.

A failed speed switch or control.

A failed motor, switch, capacitor or control board.

Frequently Asked Questions
How much does Thermador Range Hood Repair cost in your area?
Most range hood repairs fall between $100–$350 including parts and labor. The final price depends on the part that failed and your model. You get an exact quote after the diagnosis and before any work starts.
Can you repair my range hood today?
Same-day visits depend on technician availability. Call (844) 442-1500 early in the day for the best chance of a same-day or next-day appointment.
Is the repair guaranteed?
Yes. Parts and labor are covered by our 90-day warranty. If the same problem comes back within that time, we return and fix it.
Do you work on all Thermador models?
We repair current and older Thermador models. Some discontinued parts can be hard to find; if that is the case for your model, we tell you before you pay for a repair.
Should I repair or replace my range hood?
A range hood typically lasts about 10 to 20 years. If yours is well inside that range and the repair costs less than half the price of a new one, repairing usually makes sense. Near the end of its life, or when the repair costs more than half of a replacement, replacing is often the better value. We give you an honest opinion either way.
