No, not really. As the unit has to be in a level position to operate properly and not overflow. If the unit is sitting on carpet, this will often times cause the vibration noise. I don't know why, but it does and it does with my 4 year old LG unit. I have noticed, that once the tank reaches the 1/2 full point, it will vibrate sometimes. I solved the problem by firmly smacking the left & right sides of cabinet at the same time, with my open hands. The vibration stops immediately and continues to run until it shuts off because, the humidity extraction level has been reached or the tank is Full & needs to be emptied.
It's a simple solution, but it works. I hope it works for you and thanks for choosing FixYa.
With the unit
unplugged, open the cover and check the alignment of the fan. If the
fan is stuck or rubbing against the fan cowling, adjust the fan motor's
mounting hardware so that the fan turns freely.
These things tend to make a bit of noise, some more than others. You will not be able to do much about the internal produced noise but you can do a lot with the resulting vibration noise.
While the unit is running, take a few minutes and actually touch the unit ALL OVER, you are listing for any vibration noise to cease or be less so where you are touching. This includes the collection pan and the filter. Slightly Tilt the unit in all directions. Make sure that the door to the collection pan is closed properly. Take a few strips of the peel-off adhesive sided thin window/door insulation and apply to the bottom of the collector pan, if it sits ON the bottom of the unit. Place an inch or two thick blocks of foam rubber under each corner of the unit. Make sure the unit is level. Some where along here you will stifle some of, or maybe even most of the noise.
Good luck. :)
