General Electric introduces its new line of energy ecient 15’, 16’, and 18’ cu. Ft. 28” wide top freezers. The
new top freezers were designed to meet the 2014 energy regulatory requirements. Along with meeting the
new energy requirements, it has new appearance features such as , new designer door handles, GE badge
and round doors that create an attractive external appearance. The interior has a Redesigned control
housing, Z-style fresh food shelves (on some models), 8% larger vegetable pans and a 2 position freezer
shelf. A newly designs air tower improves run time and air ow. The new ice maker location and redesigned
ice bucket helps to reduce ice spillage.
• GE’s simplest door reversal ever
• Newly designed condenser (moved from bottom of fridge to rear behind access cover)
• Front serviceable Cold Control, Defrost Control and Freezer components
• Omega groove door liners for ease of replacing and adjusting door gaskets
• Durable high gloss ABS liners helps prevent cracking
• Galvanized doors for improved corrosion resistance
• Heavy duty door hinge and handle system
• Improved low friction pan slides prevent binding and squeaks
• 8% larger vegetable pans take advantage of dead air space on sides and below pans
• Freezer shelf with 2 positions adding exibility to freezer space
• New high density ice maker system makes more ice faster and takes up less space with the new
eciently designed ice bucket
• New smooth handles replace textured handles for easier cleaning
• Quick space shelf (on select models)
• Clear modular door bins (on select models)

• The ow of refrigerant through the freezer
cooling coils may make a gurgling noise like
boiling water.
• Water dropping on the defrost heater can cause
a sizzling, popping or buzzing sound during the
defrost cycle.
• A water dripping noise may occur during the
defrost cycle as ice melts from the evaporator
and ows into the drain pan.
• Closing the door may cause a gurgling sound
due to pressure equalization.
Do you hear what I hear? These sounds are normal.
• The new high eciency compressor may run
faster and longer than an old refrigerator and
might produce a high-pitched hum or pulsating
sound while it is operating.
• There may also be a whooshing sound when the
doors close. This is due to pressure equalizing
within the refrigerator.
• There may be cracking or popping sounds
when the refrigerator is rst plugged in. This
happens as the refrigerator cools to the correct
temperature.
• The compressor may cause a clicking or chirping
sound when attempting to restart (this could
take up to 5 minutes).
• Expansion and contraction of cooling coils
during and after defrost can cause a cracking or
popping sound.
• On models with an ice maker, after an ice
making cycle, ice cubes dropping into the ice
bucket may be heard.
• There may be sounds heard associated with
the fans spinning at high speeds. This happens
when the refrigerator is rst plugged in, when
the doors are opened frequently or when a large
amount of food is added to the refrigerator or
freezer compartments. The fans are helping to
maintain the correct temperatures.

Refrigerator Doors
All refrigerator doors have a galvanized treated
nish prior to painting. This treatment gives
an added protection against rust, tropical
environments, and is able to withstand highly
corrosive conditions. The refrigerator doors are a
combination of the inner liner and outer door panel
held together by interior foam. This process makes
both separate pieces one solid sturdy structure.
Both inner and outer doors are now one assembly.
Freezer Door and Hinge
Door Removal
1. Remove all food from the inner door liner.
2. Remove two T20 Torx screws and the top hinge
from the cabinet.
3. Open the door and lift it o the center hinge pin.
Fresh Food Door and Hinges
Door Removal
1. Remove all food items from the door(s). Note:
Do not lose washers on the center hinge
pin and lower hinge pin. These washers are
needed for proper door adjustment.
2. Using a 3/8 hex head driver or a #2 Phillips
screw driver, loosen and remove the center
hinge pin.
3. Tilt the fresh food door away from the cabinet
and lift up to clear the lower hinge.
To remove the hinge from the cabinet, remove the
three T20 Torx screws.
Removing the lower hinge, then remove the three
T20 Torx screws.

Door Stops
Fresh Food Door Stop
Freezer Door Stop
Door Handles
There are three types of handles, and they are
model specic:
• Stainless
• Plastic
• Pocket
The stainless and plastic handles attach similar to
both the Fresh Food and Freezer doors. They are
both secured by two #2 Phillips screws on the top
of the Fresh Food and bottom of the Freezer doors
respectively. The stainless steel handle uses a 1/8
in. Allen wrench to fasten the handles to the doors,
where the plastic handles are slotted and fastened
to a stud on both doors.
NOTE: The Pocket Handles are foamed in with the
doors and are not replaceable. If a handle is needed,
the door would need to be replaced.
Door Gasket Removal and Replacement
Both the freezer and fresh food door gaskets are
held in place by the inner door panel.
1. Pull the old gasket out of the door liner channel.
2. Soak the new gasket in warm water to make it
more pliable.
3. Using the palm of a gloved hand, push the
darted edge of the new gasket into the inner
door retaining channel.

Front Mobility Wheels and Leveling Legs
Removal
Warning: Disconnect power to the refrigerator
prior to servicing the mobility wheel assembly. Also,
before moving the refrigerator from its installation,
make sure that the leveling legs are raised to
prevent damage to the ooring.
1. Remove any items from the Fresh Food
section.
2. Safely tilt the refrigerator back.
3. Remove the three 1/4 in. hex head screws
and remove the mobility assembly.
There are two adjustable legs attached to the
Mobility Wheel assembly. Turn CCW to remove, or
raise the refrigerator and turn CW to re-assemble or
adjust.
Base Pan
The Base Pan is the foundation for the machine
compartment and adds structural strength and
stability to the refrigerator cabinet. It also adds
mobility, and is used for water evaporation. The
base pan supports the following components:
• Compressor
• Condenser/Condenser support
• Condenser fan assembly
• Wire harness
The base pan is fastened to the refrigerator cabinet
with two 3/8 in. hex head screws.
NOTE: The base pan and rear mobility wheels are
not available for replacement.
For more information about machine compartment
components, refer to Machine Compartment
section of this service guide.

The air supply, freezer return, and control panel retainers are a single piece foamed in transition that
connects the freezer to the fresh food section. This transition allows forced air to be directed from the freezer
to the fresh food section and back to the freezer through the return. The return also is used for removing
water after a defrost cycle, which drains into the control panel drain trough and out of the drain tube outlet.
The retaining clips also help secure the control panel to the ceiling of the fresh food section.
