Recently my Vent Hood is noisy when I turned on the fan.
So I checked the kitchen aid web site and it says it probably caused by Motor
I did purchase.

But the problem I face now is how to remove the fan.
There are so many screws and there is no manual describing how the cylinder shaped ventilation is attached to the hood.

I see the parts diagram but It does not tell me the proper way to disassemble.
Some screw cannot take out due to the too narrow space.

I took the photo inside my range food and I am not sure if I can simply unscrew the big (inside red in the picture)

What is the best way to try clean the parts and replace for this model inside fan (cylinder shape)

I looked at the Costco similar model but it seem to be much easier to disassemble this model make me headache.

Hi So were you able to unmount or you have the same range hood?
I have not even started (More than 4 month past)
So we cook without Ventilation now.
But I guess I have to start soon.

Thank you for your feedback
