After removing more bolts and screws than I needed to, here's how to replace the blower wheel on the stacked washer/dryer Maytag SG1000.
Turn off the power.
Remove the two screws on the access panel, which is the canted panel just below the dryer door, and remove the panel.
Remove the two screws at the top of the dryer door. These screws are on top of the dryer facing downward, and unless you're Yao Ming, you won't see them without a stepstool. You can then lift up the door and swing it out from the bottom.
There are two wires attached to the door which you should disconnect. You can set the door aside without disconnecting any other wires.
Next, remove the lint filter and the housing assembly it fits into. First, disconnect the ground wire connected to the upper-left corner of the housing, then remove 4 hex-screws accessed from inside the dryer tumbler.
You should take this opportunity to thoroughly remove lint from inside the housing.
The blower housing is now accessible. Remove the screws on the periphery of the blower housing cover (a.k.a. faceplate), and remove the cover.
The blower wheel is held in place by an external retaining ring and by a blower clamp. The replacement blower wheel came with a new blower clamp, and that clamp can be manipulated with a regular pair of pliers. I went out and bought a pair of snap ring pliers to deal with the retaining ring.
After removing the retaining ring and then taking off the blower clamp, I removed the old wheel. The new wheel was a little tough to put on, but after reading the story of the people who used a hammer to break their wheel, I just pushed on it until it popped on. I used my pliers to install the new clamp, then re-installed the retaining ring and the blower housing cover.
Reinstall the lint duct housing, making sure housing duct centers into the blower seal (looks like a felt circle). Reconnect the ground wire.
While you're inside the tumbler, at the front end of the tumbler just below the door there is a black plastic sensor with two metal bars on it called an automatic dry sensor. Fabric softener can coat the metal bars and cause the sensor to not function. Lightly sand the metal bars to remove any buildup.
Reconnect the wires to the dryer door. Reinstall the door by tilting the bottom in first, guiding the clips on the bottom of the door into the slots they fit in, then push the top of the door into position. Reinstall the screws at the top.
Reinstall the access door.
Turn the power back on! Done!
