Step 3 Gently pry the holder loose with the screwdriver; it should pop off easily.

Step 4 Place the air filter in position on the front of the power module.

Step 5 Place the holder in position on the front of the power module over the air filter.

Step 6 Press the holder firmly but gently until it snaps into place.

What to Do Next

After performing this task, replace the front cover plates.
