Before the technician arrives
A few minutes of preparation can shorten your Thermador service visit and help the technician diagnose the issue faster. Here’s what to do before your scheduled appointment.
Gather model and serial numbers
The model and serial number plate is typically found: inside the dishwasher door frame, on the refrigerator sidewall (open the door), inside the oven door frame, or on the underside of the cooktop. Write these down or photograph them — the technician needs exact model numbers to verify parts compatibility and access service bulletins.
Document the problem
Note when the problem started, how often it occurs, and any patterns (only during certain cycles, after specific events, at certain times). If there’s an error code, write it down — codes can clear after a power cycle. Take a video of the issue if it’s intermittent (a noise, a leak, a display error). This saves significant diagnostic time.
Clear access to the appliance
For refrigerators: clear items from the top and ensure the unit can be pulled forward. For dishwashers: empty the racks and clear the area under the sink. For ranges and cooktops: clear the cooktop surface and ensure the range can be moved if needed. For wall ovens: ensure the oven is cool and racks are removed.
What to expect during the visit
The technician will: verify the reported issue, run diagnostic tests (may include error code retrieval, component testing, and test cycles), explain the diagnosis and recommended repair, provide a repair estimate before proceeding, and complete the repair if parts are available — the most common Thermador parts are carried in the service vehicle. If a specialized part is needed, a follow-up visit will be scheduled.
Questions to ask
What caused the failure? Is there anything I can do to prevent this in the future? Are there other components that should be inspected while the appliance is accessible? How long should the repair last?

When DIY troubleshooting is not enough
Some Thermador refrigerator issues can be resolved with the steps in this guide. However, call a certified technician immediately if you encounter:
- Gas smell (gas models) — turn off the appliance, open windows, leave the house, call from outside
- Burning smell or smoke — disconnect power immediately. Do not use until inspected
- Electrical sparking — turn off at the circuit breaker. Wiring or component failure
- Water leaking inside walls — shut off supply and call to prevent water damage
- Error codes that return after power reset — persistent codes indicate real component failure
- Sealed system issues — compressor, refrigerant work requires EPA-certified technicians
