Is the blower deformed? Not attaching properly to the motor shaft? Is the securing collar coming off? Can you feel any paper or plastic inside against the fan fins? Is it the motor that has free play off of center or the fan cage?
I agree that is what most of the youtube videos show but it looks like this model was not produced to be able to get the housing out very easily.
The unit is 9 yrs old and has slowly developed some vibration and a kind of loose change sound when running. In looking at the unit while running the housing is shaking pretty badly when running. No small coincidence I had to replace the control board about 4 years ago due to solder connections on the board going bad.
Could it be just a dirty wheel? I guess. Could it be the motor bearings? I guess. Since the blower wheel was $100 shipped and I figured it was the problem that was my first choice of action.
Anyway. Here are 2 pics. As you can see the screws that hold the blower to the angle supports are from the backside.
ETA: After looking closer at the pics (I jammed my phone up in there) it does look like there may be the head of a screw up there I didn't see before. Gonna go look now.
