The blower wheel was a bit difficult, but manigable to do yourself.

The repair actually was quite easy but diagnosing the problem was another story. I found out that the dryer would not buzz and vibrate , if I just ran the fluff cycle but no heat. As soon as heat applied, the slight buzzing and slight vibrating would occur after a few minutes. I knew it wasn't the drum bearing, the drum rollers, the ru ... Read more bbing collar on front of drum, idle arm, belt, etc - I had replaced all of them less than a year ago. Anything I found on the internet dealing with the motor was always geared around not running or slow starting or shutting down, loud buzzing, needing a push start to start, etc but that was not the case. So I figured it was the blower housing and ordered that part. However, once I had the machine apart the blower housing seemed to be just fine - nothing obvious, everything tight. The one issue I had was removing the plastic nut with the metal insert on the blower unit that attaches it to the motor shaft which just wouldn't bulge. So I said to myself, the h*ll with it, lets get a new motor, too and remove both parts together which btw, was very easy. So that is exactly what I did. Now with new motor in hand and new blower housing in hand, I easily removed the old motor still attached to the old blower housing together and replaced both which was very easy. Hooked everything back up and no more soft buzzing or slight vibration. Now back to the problem or my guess at this point. I noticed that the rubber mounting bushing in the back of the motor which is used to attached it to the dryer bracket was funking looking - kinda soft and a bit perished. So I am surmising that once heat was introduced, it was enough to soften that bushing enough to cause the slight buzzing and slight vibration but without the heat to soften the bushing a bit, it was quiet and steady. Just a guess but for anyone that has this issue with just heat but no issue with fluff (no heat) check out the condition of that rubber mounting bushing on the rear of the motor. No where on the internet was there any info concerning the symptoms I had and I was flying by the seat of my pants. So am taking the time to get this on record in case someone else has these symptoms and finds it.
