Window Screen Removal
Depending on Model;
Older:
Remove the plastic slide track under the screen to allow it do drop down enough to removed.
Use a flat screwdriver to gently start raising the U shaped track, then slide it out by hand. To replace, slide it in by hand and then press it down.
Newer:
Lift the screen frame upward to compress the leaf springs and the whole thing lifts out of the slot at the bottom.
