I've read several reports about how "easy and quick" it was to replace the motor. All I can say is, "nonsense". It wasn't as easy as others reported, but for someone with decent tool skills, it was a very doable home repair - just be prepared to spend some time on it.
First, the motor needs to be accessed from the FRONT of the dryer. This means removing the two cover panels to access the interior. NOTE: take photos as you go of how all interior pieces for together to make reassembly easier - don't rely on memory. NOTE 2 - there are a lot of little screws holding everything together. As they are removed from each section place them in baggies and mark them as to where they go.
Once the cover panels are removed, the plenum assembly for the blower must be disassembled to access the motor. The plenum is in two main sections with several guard pieces. Photograph the pieces to aid in reassembly! Once the outer plenum cover is removed there are two external snap rings and a compression clamp holding the fan to the motor shaft. Remove them and the fan, then remove the interior plenum from the motor. There are two spring clamps holding the motor to the base. Remove them to free the motor. (Knuckle busters!) Once the motor is free, Carefully Read The Instructions for making up the new electrical connections, then change the wires from old to new. Replace the motor. The belt pulley will need to be swapped from the old motor to the new. Reassembly is opposite of above. NOTE - the spring clamps holding the motor are very hard to reconnect. To get the back one to lock into place, I had to take a round file and deepen the grooves on the clamp.
Replace the belt, blower plenum and exterior covers and everything worked fine. (I verified the motor function immediately after electrical reassembly and before putting everything back together.
