If your dryer is similar to that one. You can get to the innards from the front.
Two clips hold the lower panel on. Remove the panel and you have access to the blower, element, motor. Two 1/4 hex screws and a clip hold the blower housing on. Remove the screws, leave the clip in place and clean the inside of the housing.
No need to pull away from the wall, except the UNPLUG FIRST.

But it’s a good idea to pull away from the wall to check the vent itself.

On ours you have to tilt the dryer back and remove the two screws which hold the lower panel on.

The fire wasn't inside the blower housing, though, it was inside the case.

Believe me, that thing is cleaner inside now than it was from the factory.
