Thermador Oven Door Won't Lock
Oven Door Won't Lock 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
Dry air hardening the gasket
Very low humidity works on seal material year-round; a gasket dries, stiffens and stops recovering its shape long before it looks worn.
Worn or torn gasket material
The rubber seal hardens and cracks over years of use, especially near hinges.
Hinge or leveling adjustment drift
Heavy panel-ready doors can shift out of alignment over time, especially after a move or renovation.
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.
