LG fridge making loud noise


Bonjour,

jeepers are we talking about a wheeze, a clunk, a whirr, a buzz, a rattle, a hum, random modulated or cyclic, low or high frequency, persistent or intermittent? Or could you just be hearing fan noise.
If it sounds like tin pieces clinking against something metallic. The fan blades may be striking ice or frost or the shroud.
Could be a bad or worn fan motor bearing, or a defrost problem causing frost build up.
Just a FYI
Some LG models have been reported online as having many many operating issues.

Hope this helps

Fridgeair dishwasher not working making loud sound. water comes in and I can make it drain out but washer does not start


Hello

bearings in the heater fan may get worn out or rust. If this happens, it may become very noisy, either grinding on the bearings, or scraping against the rust. If this happens you need to replace the fan motor. Sometimes, a fan blade may come loose, and you need to replace it.
Sometimes it's the motor that makes the noise you hear. The motor has bearings in it which may become worn or get rusty. When the bearings get worn, they allow the shaft to wobble which can get quite loud. If there is a spin seal leak, water may get inside the motor, washing the bearing grease away. If the spin seal is leaking, you'll notice water leaking from under the dishwasher. There is also a disc attached to the top of the motor called a slinger. It sometimes breaks off and spins around the motor's shaft while it turns, causing some noises. You will need to replace the motor if the bearings are bad. You also need to replace the motor if the slinger is broken as well.

Newer dishwashers may make a squealing or rattling noise on the first run. This is because it has not had any water in it yet, and the motor seals are dry. You may hear this in a unit that hasn't been run in a week or more as well. You should operate the dishwasher regularly to keep the sump water from getting smelly, and to keep the seals lubricated. You can add a quart of water to the sump before running it.

Rattling noises may be produced by dishes rattling inside the dishwasher due to the water pressure from the sprayer arms on the dishes. To determine if the rattling is a loading issue, run the unit empty. If the sound is persistent, it may be that there is debris in the pump.

dishwasher water-inlet valves are noted to make a hum that lasts about 60-90 seconds several times during a washing cycle. This hum is a different hum than the sound of the motor running.

A rhythmic knocking or thumping sound may be caused the sprayer arms hitting something as they go around and around. Rearrange the dishes and resume the wash.

A clunking or clanking may be heard when the detergent cup opens; while a clicking sound may be produced by the timer or electronic control panel.

A solenoid makes a snap sound when it opens. This happens about six times during each load.

Pipes rattling or banging may be caused by a water hammer effect. Water hammer sounds are caused by a valve closing in the system, and yet the water in the pipe is still flowing because of its kinetic energy. The sound is caused by the water slamming into the closed section of pipe. A plumber can install an anti-hammer device.

Small objects can sometimes get stuck in the pump. When this occurs, you'll need to open the pump and then remove the item that is making the noise or replace the pump. The dishwasher pump is usually mounted directly to the motor and runs off the motor as well. The pump is also attached to the bottom of your dishwasher.

check that compressor is running. if your hearing a hum and then click you probably have a faulty compressor relay. most times you can pull it off and shake it and you will hear little bits rattle, well it should actually make no sound. but it could still be bad if compressor fails to run. compressor may or may not be warm.

Convection oven making rattling sound.


It is most likeky that the fan bearing is worn and thus causing the rattling sound. You will probably need to replace the fan. Check first that there is no obstacle in the way of the fan rotating.

Replacement of the fan will require the back of the oven to be removed giving access to the fan unit, which will need to have the wires disconnected and the fan assembly unbolted. Fitting is the reverse.

Always remember to switch off the power before working on electrical equipment.
