First, LG offered no support from their web site. Gas dryer is 7 years old and out of warranty. I went to YouTube and found how to dissemble my dryer (actually it was an electric unit displayed but uses the same basic parts as the gas unit. After viewing the website, I felt confident that I could find the problem and fix it. Well, happy to report great success! I saved a ton of money. I also cleaned out the inside that had a lot of dust. Should work more efficiently. I recommend this to any person good with tools.
