Oven or cooktop makes loud popping, banging, or metallic noises during heating or cooling.

Safety First: Distinguish between normal expansion noises and dangerous ignition bangs. If bangs are accompanied by visible flame bursts or strong gas odor, shut off gas and call a technician.

Step-by-step:

• Identify source: Listen carefully to locate whether the noise comes from the oven cavity, cooktop, or rear of the range.
• Tighten hardware: With power and gas off, tighten loose burner mounting screws, rack supports, and panel screws.
• Check ignition timing (gas): If the oven burner ignites with a loud bang after a delay, the igniter may be weak. Replace the bake igniter.
• Normal expansion: Some popping from sheet metal is normal as the oven heats and cools, especially on new Premier ranges. This usually diminishes with use.
