What are Common Thermador Appliance Issues?

Thermador appliances are known for luxury design, advanced technology, and professional-grade performance. Found in many high-end kitchens across the Bay Area, Thermador refrigerators, ovens, ranges, dishwashers, and ventilation systems are built to last. However, like all complex appliances, they can develop issues over time—especially without proper maintenance.

Understanding the most common Thermador appliance problems can help homeowners know when to call a professional repair service and avoid costly breakdowns. At Commercial Home Products, we specialize in diagnosing and repairing Thermador appliances using factory-approved methods and genuine OEM parts.

Thermador appliances use advanced electronic controls, sensors, and precision components. Unlike standard appliances, they require:

• Brand-specific diagnostic tools
