PERIMETER AND MULLION HOT TUBE
To reduce the possibility of condensation forming on the
exterior of the cabinet in high humidity areas, units are
equipped with a one piece perimeter and mullion hot tube
which is part of the refrigeration system. No electric
heaters are used. Refer to the Refrigeration Section for
more information.
EVAPORATOR FAN & MOTOR ASSEMBLY
The fan and motor assembly are located behind the
freezer compartment air duct directly above the
evaporator in the freezer compartment.
The fan is a suction type, pulling air up through the
evaporator and blowing it through the refrigerator com-
partment fan grille.
• With an open relay, the compressor will not start
since there is little or no current to the start windings.
The overload protector will open due to high locked
rotor run winding current.
• With a shorted relay or capacitor, the compressor
will start, and the overload protector will open.
• With an open or weak capacitor, the compressor will
start and run.but it will use more energy.
COMPRESSOR ELECTRICAL CHECK
If the compressor will not run, make a voltage check
across the power lead terminals on the PTC Relay. (See
Figure C4.)
The voltmeter should show line voltage if the thermostat
knob is in normal operating position and not in the OFF
position. If this check does not show a live circuit, the
control thermostat and defrost timer wiring should be
checked for loose or broken connections.
A control thermostat check can be made by using a
piece of wire as a temporary bridge across two thermo-
stat terminals. If the compressor starts and runs with the
bridge, the control thermostat is at fault and should be
replaced.
If a voltage check shows power supply at the PTC Relay
terminals, use a test cord to check the compressor.
If the compressor does not start and run with the test
cord, check the line voltage to see if there is more than
10% variation from the rated voltage. If the voltage is
correct and the compressor will not start and run, replace
the compressor.
If the compressor starts and runs with the test cord,
replace the PTC Relay.
On current production models, the fan blade is not
adjustable and is designed to be pressed onto the motor
shaft until it bottoms out against the stop at the front of
the fan blade.
To Remove Evaporator Fan Motor
1. Disconnect refrigerator from electrical supply.
2. Remove freezer section bottom shelves and
baskets.
3. Remove ice container and rail assembly.
Multiconnector at back of rail assembly must be
disconnected before rail assembly will come free.
4. Loosen 2 screws holding ice maker to right side
of compartment just enough to lift ice maker free.
Multiconnector must be disconnected before ice
maker will come free from compartment.
5. Remove two rail assembly supports. (two screws on
each one).
6. Remove four screws from evaporator cover.
7. Remove five screws on evaporator air duct cover.
8. Disconnect connector and green ground lead
connected to evaporator fan motor. Evaporator fan
motor assembly can now be pulled free.
9. Remove two screws holding fan motor bracket to
shroud.
10.Remove fan blade and slinger washer.
11.Remove two screws holding front and rear motor
brackets together. Pull evaporator fan motor free.
12.Reverse procedure to complete repairs.
NOTE: The Slinger washer on the fan motor shaft
must be adjusted to within
1/16”
to
1/8”
from the
motor to prevent water from entering the motor
bearing.
NOTE: When replacing the fan blade, press the
blade onto the motor shaft until the blade bottoms
out on the shaft.
