Spring startup
Before the first use of the season: 1) Remove the cover and inspect for animal nests, spider webs, and debris — especially inside burner tubes and the firebox. 2) Check all gas connections with soapy water (bubbles = leak). 3) Light each burner individually and verify even flame. 4) Clean the cooking grates with a grill brush. 5) Test the rotisserie motor. 6) Check the igniter on each burner — replace cracked or corroded ceramic rods before the season.
During grilling season
After each use: burn off residue on high for 10 minutes with lid closed, then brush the grates. Monthly: clean burner ports with a wire brush, empty and wash the grease tray, inspect the firebox for rust spots. Quarterly: deep clean the entire firebox interior, check gas line connections, lubricate the lid hinge.
Fall winterization
Thorough cleaning of all surfaces, burner tubes, and grease management. Disconnect and store the rotisserie motor indoors. Close the gas supply valve. Cover with a quality fitted grill cover. For built-in units, cover the entire outdoor kitchen if possible. Consider spraying stainless steel surfaces with a protective coating for winter moisture protection.
What NOT to do
Never use oven cleaner on stainless steel grill components. Never leave the cover off during rain or snow. Never close the lid while lighting — this traps gas and risks a flashback when ignited. Never ignore a gas smell.

Preventive maintenance saves money
Regular maintenance is the most cost-effective way to extend your Thermador grill 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
