Lg Oven Noisy Operation
LG 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.
LG 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.
LG 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.
LG 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.
LG 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.
LG Range/Stove/Oven Cooling Fan
The cooling fan runs to help keep the range itself, and its critical parts, from overheating. The cooling fan is often sold as an assembly. If the fan is noisy when it runs, the motor bearings, fan blade, or blower wheel may be worn or damaged and will need to be replaced.
LG Range/Stove/Oven Spark Electrode
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. Since the spark module sends the high-voltage pulses to the spark igniters and spark electrodes to light the burners, a malfunction spark module could prevent the oven or stovetop from lighting correctly. You should inspect the spark module for signs of burning or a shorted-out component. You can also use a multimeter to determine if voltage is reaching the spark module. If voltage is reaching the module, but the gas is not igniting promptly, it’s possible the spark module is faulty and will need to be replaced.
LG Range/Stove/Oven Control Board
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. Since the control board allows the voltage to be sent to the ignition components to light the burners, a defective control board could be the cause of the gas not igniting promptly, although this is not a common problem. You can inspect the board for burn marks or other damage, but you should confirm the other ignition components are all functioning properly before considering a control board replacement.
LG Range/Stove/Oven Spark Module
If the gas is not lighting correctly, it can build up and flash, causing a small boom noise in the oven or a “whoosh” noise on the burner. This can potentially be caused by a faulty spark module only working intermittently. You can use a multimeter to determine if voltage is reaching the spark module. If proper voltage is present, and the other oven components are all working normally, the spark module is likely defective and should be replaced.
LG Range/Stove/Oven Blower Motor
The blower motor runs to help keep the range itself, and its critical parts, from overheating and can also be used to exhaust air outdoors. The blower motor is often sold as an assembly. If the fan is noisy when it runs, the motor bearings, fan blade, or blower wheel, may be worn or damaged and will need to be replaced.
LG Range/Stove/Oven Oven Control Board
If the gas is not lighting correctly, it can build up and flash, causing a small boom noise in the oven. This can potentially be caused by a defective oven control board. However, control boards are often misdiagnosed—before replacing the control board, first check more commonly defective parts. If you have determined that all of the other components are working properly, replace the control board.
LG Range/Stove/Oven Surface Element Switch
When a surface element switch shorts out there will be a popping noise, and then the switch will stop working. Check for a shorted surface element before replacing the switch.
