After doing a bit of trouble shooting, I determined 2 of the 4 roller(s) required replacement parts. I went onto the AppliancePartsPros.com site, entered the model number and quickly determined what parts were required, placed the order for overnight delivery and they arrived on time as promised. With the support of YouTube, I found a video that provided the right level of detail watched the video and successfully dismantled and reassembled the majority of the LG dryer to complete the roller assembly repair...and while doing so...removed all lint that had accumulated over the past 7+ years.
Now I have a dryer that works like new...AppliancePartsPro.com and YouTube saved the day!!
Thanks,
Jeff
