Jenn Air Range making a loud noise
When your Jenn Air range is making a loud noise, the source is usually a damaged fan blade, especially when you hear oven fan noise, rattling, or scraping. A bent blade can slide on the shaft and rub against the housing, so inspect it for damage or excessive movement. On gas Jenn Air ranges, a faulty spark ignition switch or spark ignition switch and harness can allow gas to build up before ignition, causing a sudden whoosh or flash. A worn fan motor is another likely cause when the bearings are failing or the blower is damaged. If the noise is a boom from the oven or a whoosh from a burner, check the oven igniter. An igniter that glows for more than 90 seconds without lighting the gas may be too weak to open the safety valve. Finally, a failing convection motor can rattle, wobble, or let the convection fan strike the housing. Disconnect power before inspecting components, and use a multimeter only if you are comfortable testing continuity. Enter your Jenn Air range model number to find the exact replacement fan blade, spark ignition switch, igniter, fan motor, or convection motor for your appliance.

02 - Jenn Air Range/Stove/Oven Spark Ignition Switch
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 - Jenn Air 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.

04 - Jenn Air Range/Stove/Oven Fan Motor
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.
Highly Likely
05 - Jenn Air Range/Stove/Oven Igniter
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.
Highly Likely
06 - Jenn Air Range/Stove/Oven Convection Motor
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.
