Repair went well, replaced the pulley wheel, belt, rear drum bearing. Had an issue after replacement with the dryer stopping after ~5mins or so when running with heat. Fluff cycle would run fine.
Details:
The lock nut on the pulley wheel didn't feel tight enough so i tried to crimp it back on the pulley arm. It then became way too lose. I had to replace it with a plastic washer I had in my toolkit. That fit snug and seems to work fine. I also added some grease to the pulley shaft under the wheel.
After reinstalling their was no noise, but when running on heat the dryer would stop after 5 mins and not restart for a while. i could hear the motor slow down for a couple turns and then stop. running on 'fluff' would not shut off. my first thought was that i had either damaged a sensor, a wire wasnt connected properly or something wasn't installed correctly. After some research i thought it was the cycling thermostat, the most common cause was too much lint, blocking air flow. I had vacuumed the inside of the dryer when replacing the parts. I checked all wiring, removed the thermostat and cleaned it. Tested it with a multimeter (cool) on low ohms, went to =0. I heated the thermostat over an open flame (gas stove) and heard it click, ohms went very high..
When replacing the front panel, the inside large plastic vent/plastic insert (with light at top/vent at bottom) wasn't installed correctly. I reinstalled the thermostat and the dryer front door plastic insert correctly and the dryer is functioning properly. I did not add grease to the rear drum bearing, I may add after the fact.
