Frigidaire Oven: strange noise

Professional Repair Guide

What is this symptom?

If your Frigidaire oven is emitting strange noises like humming, rattling, or booming during operation or shutdown, it may indicate underlying issues. Common causes include fan problems, loose components, or gas igniter issues. Addressing these noises promptly can help maintain your oven's performance and safety.

Urgency: Medium

Important Tips for Frigidaire Models

  • Frigidaire acknowledges that some noises are normal (clicking, humming fans) but that other noises (rattling, grinding) often point to fan issues or ignition problems.

Possible Causes

Convection fan or cooling fan issues

How to Identify: Rattling, grinding, or squealing sounds from inside the oven or rear/top during operation, especially when the fan cycles on. Noise may continue briefly after shutdown due to cooling fan running. Sounds may change with temperature.

Part: Convection fan motor, cooling fan assembly

Loose oven racks or panels

How to Identify: Rattling or shaking noise that changes if racks are repositioned or after tightening screws. Often audible during operation when heat expands components.

Part: Oven racks, body panels

Gas igniter buildup or delayed ignition (boom/whoosh noises)

How to Identify: Boom or whoosh noise during gas oven preheat or ignition cycles, especially if preheat takes longer or ignites with delay.

Part: Gas igniter/ignition system

Normal thermal expansion sounds

How to Identify: Popping or crackling during heating or cooling that corresponds with temperature changes and is not loud or continuous.

Part: Heating elements, metal body
