Thermador Oven Overheating Lockout
An oven that will not reach temperature is a heating element, a sensor that has drifted, or a fan that has slowed — and the display is no help, because it reports what the board believes rather than what the cavity is doing.
Common Causes
Water boiling near 202°F rather than 212°F
Anything that steams or boils behaves differently at this elevation, and a cycle that never seems to complete is frequently altitude rather than a fault.
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
At this altitude there is materially less oxygen for combustion, and appliances shipped with sea-level orifices run rich until they are converted. That shows up as yellow-tipping burners, sooting and slow recovery — symptoms that look like a failing valve and are usually a conversion that never happened.

There is no emergency here, but there is a clock. Faults like this get worse on their own schedule rather than staying put, and the repair is cheaper before the failing part takes something else with it — a few days, not a few months. If you're seeing a code on the display alongside this issue, our Thermador error code guide can help narrow down the cause before we arrive. Either way, our repair service covers same-day diagnosis and a flat-rate quote before any work begins.
