RCA range makes loud popping, buzzing, or humming noises during operation.

Safety first: Disconnect power before inspecting internal components. If you see or smell burning, do not continue using the appliance.

• Identify noise source: Note whether the noise occurs during bake, broil, or surface cooking to narrow down the area.
• Inspect wiring: Remove rear and lower panels and look for blackened or loose connections at elements, terminal block, and control board. Tighten or replace as needed.
• Check fan: Spin the cooling fan motor by hand and listen for grinding. Replace if noisy or loose.
• Normal expansion: Some light popping from metal expansion is normal, but loud or continuous noises indicate a problem that should be corrected.
