18 common Thermador appliance symptoms — organized by category, with likely causes and what’s safe to check before calling.
Rather than a code number, these pages start from the actual symptom and work backward to the likely cause.
Each page below covers one specific symptom: what it usually means, the most likely causes, a few things that are genuinely safe to check yourself, and when it’s time to call a professional. If you already have an error code displayed on your control panel, our Thermador error code list is a more direct lookup.
Oven and range problems almost always trace back to the control board, a temperature sensor, or a heating element/igniter — the same handful of components across every brand.
Cooktop problems cover gas burner ignition, induction element faults, and the control board driving them — issues that show up as a burner that won’t light, won’t stop sparking, or an induction zone that won’t heat.
Refrigerator problems cover cooling, defrost, and the sensors and fans that keep a built-in unit at temperature — the same components that fail across every refrigeration brand.
Dishwasher problems usually point to a drain, fill, or leak issue — problems that are often visible, like standing water or a blinking light, before you even look for a cause.

Error codes are specific alphanumeric faults your Thermador control board displays. Symptom pages cover what you’re actually noticing — no heat, a burner that won’t light, a leak — whether or not a code is showing.
