Dacor Range making a loud noise
Is your Dacor range making a loud noise? The fan blade is the most likely cause. A bent blade or blade slipping on its shaft can rub against the housing and create an oven fan noise, rattling, or humming sound. Next, inspect the spark ignition switch and spark ignition switch and harness. If a gas burner does not ignite promptly, gas can build up and flash, causing a sharp "whoosh" noise. A multimeter can test the switch for electrical continuity. A worn fan motor can also make noise when its bearings fail or the blade or blower is damaged. If the noise occurs during baking, check the oven igniter. An igniter that glows for more than 90 seconds without lighting the gas may be too weak to open the valve, while an igniter with no continuity should be replaced. Finally, a failing convection motor can rattle, wobble, or allow the convection fan to strike the housing. Shut off power and gas before servicing, and enter your Dacor range model number to find the exact replacement fan blade, motor, ignition switch, harness, or igniter for your appliance.

02 - Dacor 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 - Dacor 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 - Dacor 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 - Dacor 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 - Dacor 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.
