Haier range makes loud popping, banging, or ticking noises during oven heating

Safety first: Distinguish between normal expansion noises and dangerous ignition bangs. If you suspect delayed ignition (loud boom with gas smell), shut off gas and call a technician.

• Normal expansion: Some popping or ticking as the oven heats and cools is normal due to metal expansion.
• Check burner mounting: Ensure the oven burner is securely mounted and not flexing excessively.
• Clean burner ports: Clean the oven burner to ensure even gas flow and reduce delayed ignition.
• Inspect for damage: Look for warped panels or loose screws inside the oven cavity and tighten or replace as needed.

Repeated loud bangs or flashes at ignition require professional gas system inspection.
