LG Front Load Dryer - 1 year old
I have read most of the past posts on "dryer rumble"
Probably rollers or welded seam
My dryer is a year old and has worked fine (small amount of rumble) for the last year.
Small amount of noise that I think it is normal.
We went on vacation to Texas for 5 months and once home I satrted it up and rumble galour. Another poster is right... it sounds like tennis shoes are in there.
We are remote and a serviceman with LG exp is 2 hours away.
This has started rumbling from "lack of use".
There's a tool that you can buy at any place that sells automotive tools, and it's called a "mechanic's stethoscope", and will sell for anywhere between $15 and $200, depending on quality and where it was made. For diagnosing problems like this, you only need a cheapie. Basically, a mechanic's stethoscope looks much like a doctor's stethoscope, but it has a metal probe that you touch to various parts of a machine. Because vibrations of solid objects cause noises like squealing, squeeking and rumbling, when you touch the metal probe to the part of the machine that's making a noise, the probe will cause a metal diaphragm to move in the same way and that same noise will be heard much louder through the earphones. Thus, a $15 mechanic's stethoscope will allow you to pinpoint the source of the rumbling noise.
But, there's lots of things that could cause a rumbling noise in a dryer. The blower wheel rubbing against something that got into the blower housing, is one. A loose clothes lifter might make a rumbling noise. Dirt on the drum rollers might make a rumbling noise. I think your best bet would be to buy a $15 mechanic's stethoscope and try and locate the source of the noise with the machine in operation (being careful to keep hands and hair away from all moving parts).
If you get no further answers in this forum, go to
Appliance repairs, Appliancehelp,
and click on the Q&A Section link. That web site is owned and operated by an appliance repair tech I met online and have known for a long time.
Maybe you can remove the panel from the unit and then plug it in and run it while observiing it's operation. This way you can see what's going on and what's causing the noise. Maybe the problem is more obvious without having to run the unit (i.e.-bad bearing, bad idler pulley, sticking spring, etc....).
