COMPONENT SERVICABILITY
DEFROST SYSTEM
The defrost heater is a radiant tube type located
between the sprial evaporator coils. Heater is
covered by a metal evaporator heater shield, and has
two metal tabs (one on either end) that hold the
shield and heater in place. Heater is a WR51M289
and should only be replace with the correct heater.
The heater is connected at both ends with a blade
type connector, in the harness. Heater resistance is
30.2 ohms. Defrost thermostat is located in the front
of the evaporator
To remove the defrost heater:
1. Remove Fresh food floor by removing 4 screws.
2. Remove evaporator heat shield from atop the
evaporator compartment.
3. With evaporator coils exposed locate two metal
engagement tabs and release shield.
4. Disconnect harness connectors.
5. Remove defrost heater.
6. Reverse to reassemble.
A water containment area is located underneath the
evaporator and is drained through a drain tube in the
back of the cabinet, just under the evaporator fan.
The tube drains through a standard “S” trap and tube
to the water pan in the bottom of the cabinet. The “S”
trap is easily removed from the back of the refrigera-
tor.
MACHINE COMPARTMENT
The condenser fan, located at the rear of the ma-
chine compartment, draws air through the base grille
from the front of the refrigerator. Air flow then
continues through the condensor picking up heat. A
floor in the cabinet under the condenser and the
foam gaskets on the condener fan opening prevent
air from bypassing the condenser. The rear access
cover must be kept tightly attached to the cabinet to
prevent air bypass. The heat exchanger cover in the
back provides 1- 1/4” clearance which is adequate
for ventilation for this refigerator.
To remove the condenser fan:
1. Disconnect harness connector to fan motor.
2. Remove three screws from fan housing to fan.
3. Remove 1/4” nut from fan blade while still in
housing with motor loose.
4. Rotate motor out of condensor fan housing.
5. Reverse procedure to reinstall.
