Call us — we've seen most Thermador codes in the field. transparent service-call pricing (applied to repair).
Error code meanings are based on field observation by our technicians. Some codes may indicate multiple underlying issues — a diagnostic visit confirms the root cause. We are an independent appliance repair service and not affiliated with Thermador or its parent manufacturer. Codes shown reflect common scenarios across the Thermador product line; specific behavior may vary by model year and configuration.
How our repair process works
Five steps from your first call to the warranty receipt. No surprises.
- 1
Inspection
Your technician examines the appliance, listens to your description, and notes the model + serial for parts lookup. Visual + audio-based diagnostics first — non-invasive.
- 2
Diagnostics
Targeted tests on the failing subsystem (compressor, control board, heating element, motor, etc.) to identify the exact root cause. You get a clear explanation, not jargon.
- 3
Fix decision
Up-front estimate before any work begins: cost, parts, and the realistic likelihood of success vs. recommending replacement on an old or uneconomical unit. You decide.
- 4
Operational test
After the repair we run the appliance through its normal cycle on-site — never "it should work now, call us if it doesn't." You sign off when it's actually working.
- 5
Warranty + consultation
Receipt with warranty terms in writing. Plus a quick walkthrough of how to extend the appliance's life (filter cleaning, drain maintenance, etc.) — included free.
