Gaggenau Range making a loud noise
If your Gaggenau range is making a loud noise, the source is usually a damaged fan component or a gas ignition problem. A bent or loose fan blade can slide on its shaft and rub against the housing, creating oven fan noise or a rattling sound. If the noise is a sudden whoosh or flash at a burner, a faulty spark ignition switch is a likely cause. An intermittent spark ignition switch and harness can cause the same gas buildup and ignition noise, so test the switch for continuity with a multimeter. A worn fan motor may also produce loud humming or rattling when its bearings fail or the blade or blower is damaged. If the noise sounds like a small boom in the oven, the igniter may be weak and allowing gas to build up before ignition. On convection models, a failing convection motor can rattle, wobble, or let the fan hit the housing. Disconnect power and shut off the gas before inspecting or testing parts. Enter your Gaggenau range model number to find the exact replacement fan blade, spark ignition switch, harness, fan motor, igniter, or convection motor for your appliance.

02 - Gaggenau 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 - Gaggenau 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 - Gaggenau 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 - Gaggenau 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 - Gaggenau 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.
