One of the most common causes of clothes feeling overly hot is a clogged dryer vent system. It can be the exhaust on the exterior of the home or the duct-work leading from the transition hose (Slinky tube) through the wall to the exterior of the home.
Either way if the heat and moisture are not being expelled properly then this (on fire) feeling can occur " literally " (main reason for getting into this profession as a retired firefighter). Either have a professional clean your ducting or if you are up to the task do it yourself, but make sure you have a very, very good air flow at the exhaust point outside the home.......

Thanks for your advice. I had already made sure that the vent and slinky hose were cleaned out. But, with your suggestion, i replaced the outside vent and replaced slinky hose. Still having the issue. If you have any other suggestions, THANKS in advance.
