if im honest, and im sure the rest of the guys will agree.. that particular dryer is an absolute nightmare to work on
to get to where you need to be, its a lid off/ front off/duct off/ drum out job… with lots of sharp edges and tightly, badly positioned wiring that tends to pull off its relative position
then youve gotta hope you find the leak, because your gonna have to reassemble it fully to test it.. and if it leaks… disaster
not a nice dryer to work on, and thats the reason people are hesitant
sorry to come across negative, but honesty is a policy we use keenly
