If your RCA range is making a loud noise, the fan blade is the most likely cause. A bent blade or one sliding on its shaft can rub against the housing, creating oven fan noise or a rattling sound. Inspect the blade and replace it if damaged. A faulty spark ignition switch, or the spark ignition switch and harness, is another common cause, especially when you hear a sudden whoosh from a gas burner. Intermittent ignition can allow gas to build up before it lights. Test the switch for electrical continuity with a multimeter. A worn fan motor can also cause an oven making noise, humming, or rattling because of bad bearings or a damaged blower. If the RCA range oven makes a small boom or whoosh, check the igniter. An igniter that glows for more than 90 seconds without lighting the gas may be too weak, while one that does not glow should be tested for continuity. Finally, a faulty convection motor can make noise when its bearings fail or its shaft wobbles. Enter your model number to find the exact replacement part for your RCA range.
01 - RCA 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 - RCA 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.
