Rollers
The rollers have 3 purposes:
Rollers adjust so the door closes easily when opened about halfway.
1
[Raise the front about 5/8 (15 mm) from the floor.]
Rollers adjust so the refrigerator is firmly positioned on the floor

and does not wobble.
Rollers allow you to move the refrigerator away from the wall for cleaning.

To adjust the rollers, remove the base grille by pulling it out at the bottom.
Turn the roller adjusting screws clockwise to raise the refrigerator,
counterclockwise to lower it. Use an adjustable wrench (3/8 hex head bolt)
or pliers.
To replace base grille, align prongs on back of grille with clamps in cabinet and
push forward until grille snaps into place.
