3-7 LEVELING AND DOOR ALIGNMENT
(a) LEVELING
Your refrigerator has two front leveling screws one on
the right and one on the left. If your refrigerator seems
unsteady or you want the doors to close easier, adjust the
Refrigerator’ s tilt using the instructions below:
1. Plug the refrigerator’ s power cord into a 3-prong
grounded outlet. Move the refrigerator into its final
position.
2. Turn the leveling screw clockwise to raise that side of
the refrigerator or counterclockwise to lower it. It may
take several turns of the leveling screw to adjust the tilt
of the refrigerator.
NOTE: Having someone push against the top of the
refrigerator takes some weight off the leveling screws.
This makes it easier to adjust the screws.
(b) DOOR ALIGNMENT
If the space between your doors is uneven, follow the
instructions below to align the doors:
1. With one hand, lift up the door you want to raise at
middle hinge.
2. With other hand, use pliers to insert snap ring as
shown.
3. Insert additional snap rings until the doors are aligned.
(Three snap rings are provided with unit.)
Fig. 28
3. Open both doors again and check to make sure that
they close easily. If not, tilt the refrigerator slightly more
to the rear by turning both leveling screws clockwise. It
may take several more turns, and you should turn both
leveling screws the same amount.
4. Re-adjust if necessary.
5. Replace the base cover.
NOTE: Your new refrigerator is uniquely designed with
two fresh food doors. Either door can be opened or
closed independently of one another. You may have to
exert slight pressure on doors to get them to close
completely.
