Clothes wouldn't dry completely

Used a 1/4 inch nut driver to remove back and remove element and cycling Thermo. Prior to ordering parts, I looked at the instruction videos provided with each part. ding the backand 3 holding the heat control and element. The belt is a little different, you have to open the machine from the front. There are 4 screws that need to be removed. The videos show exactly what to remove and how to check belt alignment. ---- With the videos, and list of parts that could fail, you can't miss. I have ordered all of the parts to fix the cold air cycling system in our Ref/Freezer. The cost of all the parts is so minimal compared to a service call, it doesn't make sense to eliminate a few parts that they list as possible problem parts when you are not 100% positive what is causing the failure.----- The dryer works exactly like it did when it was new.
