When your Frigidaire range is making a loud noise, the sound usually comes from a moving fan part or a gas ignition problem. A bent or loose fan blade is the most likely cause of oven fan noise because it can slide on the shaft and rub against the housing. If you hear a whoosh or small boom when a gas burner or oven lights, a faulty spark ignition switch or spark ignition switch and harness may be allowing gas to build up before ignition. A worn fan motor can also cause humming, rattling, or grinding when its bearings fail or the blade or blower is damaged. If the noise occurs during gas oven operation, inspect the oven igniter. An igniter that glows for more than 90 seconds before lighting may be too weak to open the gas valve. On convection models, a failing convection motor can rattle or allow the fan to hit the housing. Unplug the range and shut off the gas before testing or replacing parts. Enter your Frigidaire range model number to find the exact replacement fan blade, motor, igniter, or switch for your appliance.
01 - Frigidaire Range/Stove/Oven Fan Blade
The fan blade may be bent or sliding on the shaft and rubbing on the housing. Inspect the fan blade. If the fan blade is bent or damaged it will need to be replaced.

If the gas is not lighting correctly, it can build up and flash, causing a “whoosh” noise on the burner. This can potentially be caused by a faulty spark ignition switch only working intermittently. You can use a multimeter to test the spark ignition switch or switches for electrical continuity to determine if the component is functioning normally.
03 - Frigidaire Range/Stove/Oven Spark Ignition Switch and Harness
If the gas is not lighting correctly, it can build up and flash, causing a “whoosh” noise on the burner. This can potentially be caused by a faulty spark ignition switch and harness only working intermittently. You can use a multimeter to test the spark ignition switches for electrical continuity to determine if the assembly is functioning normally.
The fan motor turns the fan blade to circulate the air. The fan motor is often sold as an assembly. If the fan motor bearings are bad, or the fan blade or blower is damaged, the fan motor will need to be replaced.
If the gas is not being ignited promptly, it can build up and flash causing a small "boom" noise in the oven or a "whoosh" noise on the burner. A faulty igniter could be the cause of the gas not igniting promptly. To determine if the igniter is defective, observe the igniter when the oven is on. If the igniter glows for more than 90 seconds without igniting the gas flame, this indicates that the igniter is too weak to open the valve. If the igniter is weak, replace it. If the igniter does not glow at all, use a multimeter to test the igniter for continuity. If the igniter does not have continuity, replace it.
The convection motor drives the convection fan to circulate the air inside the oven. The convection oven must circulate the air for the oven to heat evenly. If the motor bearings are bad the motor may rattle or the fan may hit the housing. If the convection fan motor shaft wobbles, or the motor is making a loud noise, replace the convection motor.
