Gas oven on Zline range will not ignite; you hear clicking but no flame.

Safety first: Turn oven OFF. If you smell gas, shut off the gas supply and ventilate immediately.

• Check gas supply: Confirm that other gas burners work. If cooktop works but oven does not, the oven gas valve or safety system may be at fault.
• Observe igniter: For hot surface igniter models, the igniter should glow bright orange. A weak or dull glow often cannot open the gas valve and must be replaced. For spark models, verify a strong spark at the oven burner.
• Clean burner: Remove the oven bottom panel to access the burner. Clean burner ports with a brush to remove debris that may block gas flow.
• Professional testing: Gas valve and safety circuits should be tested by a qualified technician using proper instruments.

When to call a technician: Oven gas components are safety-critical; if cleaning and basic checks do not restore ignition, schedule professional service.
