Oven makes loud popping or buzzing noises when heating on a Magic Chef oven.

Safety first: Turn off the oven and the breaker immediately if you hear loud pops or see sparks.

• Inspect elements: Once cool and power is off, examine the bake and broil elements for cracks, burn marks, or spots where the element has blown out. Replace any damaged heating element.
• Check terminals: Remove the rear panel and inspect element terminals for loose or burnt connections. Tighten or replace terminals and wires as needed.
• Remove foreign objects: Ensure no foil, racks, or utensils are touching the elements.
• Relay noise: A faint click is normal, but loud buzzing from the control area may indicate a failing relay. Replace the electronic oven control if buzzing persists and heating is erratic.

When to call a technician: If you are unsure of the noise source or see significant arcing damage, professional service is recommended.
