Code-specific guidance for F4
If your Oven shows F4, treat it as a prompt to verify basics from the manual—power, gas shutoff position where applicable, ventilation clearance, and door or lid closure—then avoid hammering resets if the code returns during ordinary use.
Keep the manual’s chart page handy; it often lists whether the code blocks heating or is informational only for your series.
Reach Thermador Support at 844-683-0648 so we can align the Oven symptoms with the right diagnostics path.
What to track before you call
- Exact timing: note which cycle step, mode, or temperature setting triggered F4.
- 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.
