I wanted to avoid pulling the drum. Luckily, my blower was easily accessed by pulling the front bottom panel. A couple of sheet metal screws were all I needed to remove the fan housing cover. I knew the fan was on reverse threads, i.e. righty-untighty. As it spins it tightens so no need for a retaining nut. I took off a screw holding on the exhaust tube and wiggled it out. I found the broken teeth inside. With the tube out of the way I was able to slide a crescent wrench in back and place it on the end of the back shaft. It wasn't a true nut, more a flange but with some positioning I got the crescent to stay on. Now, just turn the fan left and it should spin off. No. Like I said, it tightens as it spins so it was on there. I tried 'shocking' it with a few hammer raps, WD 40, my most creative curse words. It wouldn't budge and I was reluctant to force it for fear of damaging the shaft. I ended up using a Dremel tool and cut the plastic fan off. I was left with the metal center of the fan that screwed on to the shaft's threads. Carefully I cut that until I was able to peel it off the threads. I spun the new fan on and put things back together. The dryer is nice and quiet again. In the end, did I save any time or work accessing it from the front? Probably not but it was not a question of how much work, but of what type of work did I want to do. I love the Dremel and am fairly handy with it. I've opened appliances before and it is tedious with all the screws and pulleys and belt threading, plus I always manage to cut myself up on the sheet metal. So, pick your poison. In the end it's all work but not hard or impossible. Saved time and money and got that accomplished feeling DIY's live for. Hang in there, you can do it. Oh yeah, APPros were fast and accurate and the best price I found. They also took care to send me status updates on my shipping. It felt like they were as concerned about my repair as I was.
