Hey, thanks for posting this video. I was grateful you showed us what to look for and how to fix it. I was able to fix mine just through the opening of the vent hole. I have little arms so I could see what I needed to do. My husband helped (using his manpower) to unscrew the screw on the arm, tighten up the new one and also stretch the arm and hook the belt on. I was able to place the arm in the correct spot, start the screw placement and adjust the belt to the right position. You save us hundreds of dollars. Thanks for sharing your skills with us.
Is the dryer completely dead as in no display?? If so your breaker may have tripped.. If you do have power did you flip the top open, is the belt tight and can you spin the drum manually like I did at 09:09??
