COMPONENT REMOVAL
This section explains how to remove components from 736 Series Units starting with serial # 2970000.
If different models have similar adjusting, accessing and/or removal procedures, they are grouped together under
the appropriate heading. The units covered in the procedures are listed between brackets after the heading. This
section is arranged as follows: Exterior cosmetic and mechanical components, followed by the internal cosmetic
and mechanical components, unit tray mechanical components, with the sealed system components at the end. An
attempt has been made to arrange these procedures in such a way as to simulate which components would need to
be removed first in order to gain access to other components. When following a component removal procedure, it
may be necessary to reference another component removal procedure listed earlier in this section.
NOTE: Before continuing, please take note of the WARNINGS and CAUTIONS below.
- IF IT IS NECESSARY TO REMOVE A UNIT FROM ITS INSTALLATION, REMEMBER THAT THE UNIT
COULD TIP FORWARD WHEN PULLED FORWARD BEYOND THE ANTI-TIP COMPONENTS, RESULTING
IN SERIOUS INJURY OR DEATH. PULLING A UNIT FROM ITS INSTALLATION SHOULD ONLY BE PER-
FORMED BY AN AUTHORIZED SERVICE TECHNICIAN OR INSTALLER.
- TO AVOID ELECTRIC SHOCK, POWER TO THE UNIT MUST BE DISCONNECTED WHENEVER ACCESS-
ING AND/OR REMOVING COMPONENTS POWERED BY ELECTRICITY OR COMPONENTS NEAR OTHER
ELECTRICAL COMPONENTS. IF THE UNIT IS PLUGGED IN, BUT HAS NOT BEEN SWITCHED ON BY
PRESSING THE UNIT ON/OFF KEY, POWER IS STILL PRESENT AT THE CONTROL BOARD.
- IF REMOVING A DOOR OR DRAWER FROM A UNIT, REMEMBER THAT DOORS AND DRAWERS ARE
HEAVY. IF THEY WERE TO FALL, THEY COULD CAUSE SERIOUS PERSONAL INJURY.
- If removing or disconnecting door hinge assemblies, remember they are spring loaded and may recoil
quickly when released.
- If working in the compressor area, remember that compressor and tubing may be hot.
- If working on or around the evaporator or condenser, remember that evaporator and condenser fins are
sharp.

Condenser Fan Assembly Removal
The condenser fan shroud sets on top of two pegs pro-
truding from the unit tray and two screws at the top of
the shroud secure it to the condenser. The condenser
fan is mounted to the condenser fan shroud. Three fan
mounting brackets are hooked into grommeted holes in
the fan shroud. Screws passing through these brackets
secure the fan motor to the brackets. The condenser
fan blade is held onto the fan motor shaft with a nut.
To remove the condenser fan assembly, the
kickplate/grille will need to be removed first and the unit
tray will need to be slid out. To slide the unit tray out,
extract the two screws that secure the tray to the unit,
located at the front right and left corners. Grab the front
flange of the tray and pull forward. (See Figure 7-40)
NOTE: It may be necessary to disconnect the com-
pressor electrical leads in order to pull the tray out far
enough to access the condenser fan assembly.
1. Disconnect condenser fan motor electrical leads.
(See Figure 7-41)
2. Extract screws at the top of the fan shroud and lift
the shroud with motor, up off of the pegs located on
unit tray. (See Figure 7-41)
3. Remove condenser fan from shroud by extracting
the screws securing the motor to the brackets. The
brackets will unhook from the grommeted holes in
the condenser fan shroud after the screws are
removed. (See Figure 7-42)
4. To remove fan blade from the fan motor, grab the
blade and motor while turning the nut counterclock-
wise. Then pull the blade from motor shaft. (See

SEALED SYSTEM COMPONENTS
Upper Refrigerator Compartment Evaporator
Removal (736TR, 736TCI)
The upper evaporator is attached to the back wall with
screws.
NOTE: Before attempting to remove the evaporator,
evacuate the refrigerant from the sealed system.
To remove the upper evaporator, first remove the light
diffuser and evaporator cover, then (See Figure 7-43):
1. Extract screws securing evaporator to the back
wall.
2. With a tube cutter, cut inlet tube approximately one
inch from the end and cut the outlet tube approxi-
mately two inches from the end.
NOTE: Sweating the joints apart is not recommended
as this may induce moisture into the sealed system and
could cause a solder restriction in the capillary tube.
NOTE: When installing a new evaporator, be sure to
thoroughly clean the tubing before brazing. After brazing
and inspecting the joint for leaks, it is recommended to
apply an acrylic-based paint to the joints to protect the
exposed metals from oxidation.
Lower Compartment Evaporator Removal
The lower evaporator is attached to the back wall with
screws.
NOTE: Before attempting to remove the evaporator,
evacuate the refrigerant from the sealed system.
To remove the lower evaporator, first remove the heat
exchanger cover, evaporator cover and on the 736TCI
the wire cover. In the model 736TCI, the evaporator fan
shroud will also need to be removed, then (See Figure
7-44):
1. Extract screws securing evaporator to back wall.
2. With a tube cutter, cut the inlet tube approximately
one inch from the end.
3. With a tube cutter, cut the outlet tube approximate-
ly two inches from the end.
NOTE: Sweating the joints apart is not recommended
as this may induce moisture into the sealed system and
could cause a solder restriction in the capillary tube.
NOTE: If reusing the existing defrost heater, defrost ter-
minator and evaporator thermistor, they can be removed
from the evaporator after it is removed from the unit.

High-Side Filter-Drier Removal
The high-side filter-driers are located in the center of
the unit tray, behind the condenser and are attached to
the drier bracket with a cable tie.
NOTE: Before attempting to remove a filter drier, evac-
uate the refrigerant from the sealed system.
To remove a high-side filter-drier, the kickplate/grille will
need to be removed first and the unit tray will need to
be slid out. To slide the unit tray out, extract the two
screws that secure the tray to the unit, located at the
front right and left corners. Grab the front flange of the
tray and pull forward. (See Figure 7-45)
NOTE: It may be necessary to disconnect the com-
pressor electrical leads in order to pull the tray out far
enough to access the filter-driers.
1. Remove a filter-drier by cutting the cable tie which
secures filter-driers to the bracket. (See Figure 7-
46)
2. With file edge, score a line around capillary tube
approximately one inch from filter-drier outlet, then
fatigue capillary tube at this line until it separates.
3. With a tube cutter, cut the inlet tube approximately
one inch from filter-drier.
NOTE: Sweating the joints apart is not recommended
as this may induce moisture into the sealed system and
could cause a solder restriction in the capillary tube.
NOTE: Check the end of the remaining capillary tube
for internal burrs. If burrs exist, re-score a line around
the capillary tube (approximately one inch from the end)
and fatigue the capillary tube at this new line until it
separates.
NOTE: When installing the replacement filter-drier,
insert the capillary tube until it touches the screen, then
pull the capillary tube approximately 3/8” away from the
screen before brazing. (See Figure 7-47) When
installing a new filter-drier, be sure to thoroughly clean
the tubing before brazing.
