Question about LG LRBN20510WW Bottom Freezer Refrigerator

3 Answers

Noisy vibration Our LG fridge makes a vibrating sound that has become progressively louder. I took off the aluminum back panel and saw the condenser, condenser coils and the fan, but no other moving parts. The noise seems to be coming from inside the fridge but I can't figure out where. The fridge seems to be working fine but with this noise I am aware of how frequently it runs and I wonder if this is normal.

    I don't see ice but after reading lots more of the (ahem) virtues of the LG fridge on line, I listenend int the freezer and the noise was much louder from there. So, a good defrosting will help?

    Is there a build up of ice on the rear wall of the freezer?

    How long have you owned it and when did it start. I had a similar problem, which was the lower fan blades hitting ice build up where you can't see it.

Heater of defrost controls appear to be bad. If you need to melt out by hand then your auto defrost is not working. These are now solid state with sensors. Old friges were must easier to repair.

    This is sounding more like incomplete defrost problem that LG needs to address. If there is ice build up and defrost is working then it is a factory flaw. There should never be ice build up in a properly working frig.

I had the same problem. Here is my fix: - remove both side rails inside the freezer (3 screws each) - remove the back panel inside the freezer (2 screws) - I found there a large (4 inch x 4 inch x 6 inch) block of ice that was interfering with the fan - gently remove the ice (I used a hair dryer) - clean and dry all parts - re-install back panel and side rails

Remove the back panel inside the freezer (if there's a removable panel there. There is a fan behind it - may be source of your problem.

New LG French Door fridge w/fzr on bottom a buzzing sound is coming from the unit.If I open a door it stops but comes back when I close. I can apply pressure on the casing and quiet it. Any ideas?

Try attaching a clothes peg to the condenser which is the ********* attachment on the back of the unit.first off make sure that the appliance is level as any vibration will cause the noise you're describing.N.J.T.

Westinghouse virtuoso fridge is noisy after leaving the freezer door open several hours


First analyze from where you are getting the sound.
1)Check the fan at the back side of the freezer.Is it making noise.Remove it and put some oil so it will rotate without sound.Check for the bending and straighten it and see it
doesn't hit on body.

2)compressor motor may vibrating a lot making noise to the condenser coils.It makes the full fridge to vibrate and makes noise.Adhesive stickers will soften them.If still problem persist coil could be damaged.

post a comment for further assistance.

My fridge has become very noisy? Could you advise?

The fault can be the vibration of the compressor motor radiating the noise to the condenser coils. So it may be hitting against the walls of the fridge and you are getting this noise. Also tthe compressor makes tteh vibration that transmits to plastics, trays at the bottom of fridge and the rear mounting. Use good adhesive stickers to soften them.

Machine vibrating and grinding at the bottom of the machine

if noise stops when you put youre hand on bottom panel(vibration) then it will probably need a new drain pump as they wear out they can become noisy and make the panel buzz.

Maytag side by side fridge makes vibration noise

Mine is a different model, and less than three years old, but the vibrating noise was really annoying. I would shift the unit or the door slightly, and it would stop for a while, as you reported. I took a few minutes, applied pressure to different areas, up and down, inside and out. The noise was louder near the floor. I removed the plastic grill and applied upward pressure on the wires covering the coils - it was loose. I noticed an accumulation of dust, and vacuumed as far as I could reach around the underneath area; also pulled fridge out and vacuumed a dust-covered vent on the back near the floor. Was planning to insert some kind of wedge under the loose part, but when I put everything back in place, the vibration stopped - now I only hear a gentle hum. Seems I did something right in this process.

LG flat screen TV speakers make a vibrating noise

I have this problem with my 37LG30.
They all seem to have the same factory flaw.
The plastic bezel and rear is vibrating against itself I have found.

Tonight, just now, I just took all the front bezel screws out,(from the back) loosened the other 4 big screws in the rear center(I don't recommend removing them)and loosened the stand screws also and tried separating the bezel from the back as I went around the set. This did not really help much except around the bottom where the noise/vibrating comes from-the speaker area.
The two plastic pieces are vibrating against one another.
The vibrating was coming from the speaker area without doubt.
The next thing was to try separating at the bottom where the speakers are with my fingers and a stiff metal nail file carefully..fingers seemed to work best for me.
As I separated the front bezel from the rear housing (at the speaker location)most if not all the buzzing/vibrating /distortion went away.
I then inserted small pieces of cotton (you can use felt, or similar I suppose) and buttoned it all back up;put the screws in
Almost all the distortion and speaker buzz/vibratingis gone except on very low frequencies.
good luck!

Haier ESA 3185 AC won't cool; makes escalating loud vibrating noise near front panel/ filter

Have someone check the run capacitor of this unit. If the run capacitor is bad over shorted it can cause the unit to run and short cycle on a current overdraw. This makes for an electrical imbalance in the compressor motor. Next step is the compressor is faulty.
