Pro Grand overview
The Thermador Pro Grand is available in 48″ and 60″ configurations, offering the most comprehensive cooking capability of any home range. The 48″ model includes 6 Star Burners, an electric griddle, a convection oven with steam assist, and a warming drawer. The 60″ model adds 2 more burners for a total of 8.
Griddle maintenance
The integrated electric griddle requires regular seasoning — apply a thin layer of high-temperature cooking oil after each use. Clean while warm with a flat scraper, not abrasive pads. If the griddle heats unevenly, the electric element beneath may have a partial burnout — this is a serviceable component.
Steam oven care
The steam-assist feature uses a water reservoir and steam generator. Descale the generator every 3-6 months (more frequently with hard water) using the built-in descaling cycle or a citric acid solution. Empty and refill the water reservoir before each steam cooking session. After steam cooking, leave the door ajar for 15 minutes to allow moisture to evaporate from the cavity.
Warming drawer
The warming drawer maintains food at serving temperature (typically 140-200°F). Don’t use it for cooking or reheating cold food — it’s designed to hold already-cooked food warm. Line with foil for easy cleanup. The drawer has its own heating element and thermostat — if it overheats or won’t warm, these components can be serviced independently.
Dual oven management
The Pro Grand’s dual ovens can run at different temperatures simultaneously. Use the larger oven for main dishes and the smaller for sides or desserts. Both have True Convection with independent fans. Self-clean one oven at a time — running both in self-clean mode simultaneously draws excessive current.

- Document issues before calling — note error codes, symptoms, when they started, and patterns. This helps the technician diagnose faster
- Use surge protectors — power fluctuations damage electronic control boards. A quality surge protector protects your investment
Preventive maintenance saves money
Regular maintenance is the most cost-effective way to extend your Thermador range lifespan and avoid expensive emergency repairs.
- Annual professional inspection — catches wear before failure. Critical for gas connections, sealed systems, and electronics
- Filter replacements on schedule — water, air, and carbon filters have finite lifespans. Running past service life degrades performance
- Gasket and seal checks — door gaskets and hose connections develop micro-leaks over time. Quarterly visual inspection prevents damage
- Cleaning as maintenance — buildup of grease, food debris, mineral scale, and dust directly contributes to component failure
