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.

COMPONENTS

Kickplate/Grille Removal (All Models)

The kickplate/grille is attached by four screws passing

through the kickplate into adjustable kickplate brackets.

NOTE: Because drawer panels may extend down in

front of the kickplate/grille, it may be necessary to

remove the bottom drawer to gain access.

To remove kickplate/grille, extract screws (two each

side) and pull kickplate/grille forward. (See Figure 7-1)

Side Molding Strip Removal (All Models)

Side molding strips are held in place by four unit-to-cab-

inet brackets attached to the sides of the cabinet.

To remove the side trim molding strips (See Figure 7-2):

1. Place a straight-blade screwdriver in channel at

bottom of molding. Gently pull molding forward

until face-frame edge of molding is accessible.

2. Place another straight-blade screwdriver under

face-frame edge and gently work molding away

from face-frame, and off of unit-to-cabinet brackets.

Upper Compartment Light Switch & Fan Switch

Removal (All Models)

The upper door compartment light switch and fan switch

protrude through the top trim molding, just above the

door. Tabs on the switches hold switches in the switch

bracket behind the top trim. The bracket is attached to

the switch enclosure with screws.
