Thermador Oven Not Heating
Oven Not Heating is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
A circuit sized for a very different kitchen
Wiring in a pre-war building was never intended to carry a modern range, and an element that never reaches temperature is often a supply problem rather than a failed element.
A failed bake or broil element
The most common cause of a full loss of heat in an electric oven.
A drifted temperature sensor
Electronic sensors drift out of spec gradually, so the oven can run well off-target without any error showing.
Local conditions that matter here
A range in a pre-war San Francisco kitchen is usually sitting in an opening cut for something much smaller, on a supply sized for another century. Before a burner or igniter fault gets blamed on the appliance, it is worth knowing whether the gas line and the circuit behind it were ever sized for it.
