Only a tech with special equipment can test this, however if it's scorched, then that's what to replace.

What Happens with a Bad Thermostat in a Clothes Dryer?

Symptoms of a bad dryer thermostat include air that won't heat. A faulty dryer thermostat can result in a dryer that stays on too long or overheats. A faulty dryer thermal fuse can prevent a dryer from switching off when it dangerously overheats.

Each bend in the ductwork subtracts from the maximum length allowed. Here's the International Code on the subject: What is the maximum length for a clothes dryer vent?.

Best guess is cleaning the pins + control board since that is what affected the problem the most of the things you did. Anyway, we can put this thread to rest unless others have further comments.
