Replacing the fan on your aF4 is a relatively simple process and should be done every 2-3 years or if the fan is making a rattling sound or has completely stopped.

Step 1
Remove the cup and the lid, then turn the aF4 upside-down.

Step 2
Remove the 4 silver screws in the corner of the unit.  Carefully turn the aF4 right side up.

Step 3
Remove the housing and take note of the tubing orientation so that you can re-assemble correctly.

Step 4
Remove the faulty fan.  Install the replacement fan.  

Step 5
Reinstall the housing and test the fan.
