Code-specific guidance for E118
E118 on this Oven family is best read alongside how heat feels at the burner or in the cavity, whether fans run, and whether alarms repeat after you complete the manual’s safe steps.
Do not disassemble sealed burner boxes or high-voltage ignition areas without training—what you see on the glass is enough for dispatch.
For next steps, contact Thermador Support at 844-683-0648 with model, serial, and what you observed—we service Thermador kitchen appliances as an independent team and are not a factory-authorized dealer.
What to track before you call
- Exact timing: note which cycle step, mode, or temperature setting triggered E118.
- Repeatability: record whether the code returns immediately after reset or only under heavier demand.
- Related symptoms: capture any unusual sounds, heat changes, leaks, smells, or electrical trips.
- Model details: keep model and serial ready so we can route the right parts and test path.
