I think you said LG. Are you guys certified in LG washer/dryers? I have a dryer that runs hot even at medium temperatures. There's a vent at the back of the drum, and it is burnt slightly. I'm pretty sure that part is under warranty. But, also, it could be the exhaust pipe. It's 15 ft. long, and it might need to be cleared out.

This is Viking Repair Service, but yes, we also service LG appliances. If the unit is still under warranty, it could void the warranty if we work on it since we're not certified for LG appliances, only Viking. You can call the manufacturer to see if they can help you since it's still under warranty. If they can't help you, you can give us a callback.
