Strong gas smell when using a gas oven, especially at startup.

Safety First: If you smell strong gas, turn off the oven and gas supply immediately, ventilate the area, and do not use open flames or switches. Contact a qualified gas technician.

• Check for delayed ignition: If you notice a puff of flame or boom at ignition, the bake igniter may be weak and should be replaced.
• Inspect connections: With gas off, inspect the gas line connections at the rear of the range and the internal manifold for signs of leakage (use a leak detection solution when gas is turned back on).
• Burner inspection: Check the oven burner tube for cracks, corrosion, or misalignment with the igniter and orifice. Replace the oven burner assembly if damaged.
• Professional service: Any suspected gas leak or combustion issue should be handled by a licensed gas technician.
