Lower Evaporator Fan Assembly Removal
(736TCI)
The evaporator fan assembly is attached to the upper
back wall of the lower compartment with screws.
To remove the fan assembly, first remove drawers, left
side drawer slides, heat exchanger cover, evaporator
cover and the fan shroud, then
1. Disconnect fan wire leads from wire harness.
2. Extract fan assembly mounting screws from back
wall and pull fan assembly from unit.
NOTE: The evaporator fan blade is pressed onto
the fan motor shaft so it can be removed by simply
pulling it away from the motor.
Defrost Terminator Removal
(736TFI & 736TCI)
The defrost terminator is attached at the top of the
evaporator to the second tubing pass, which is the top
rear tube of the evaporator.
To remove the terminator, first remove drawers, left side
drawer slides, heat exchanger cover, evaporator cover
and the evaporator fan shroud, then
1. Extract screws from top of evaporator, then loosen
bottom screws and pull top of the evaporator for-
ward.
2. Disconnect defrost terminator electrical leads.
3. Pull terminator from evaporator tubing.
NOTE: When reinstalling the defrost terminator, it must
be attached to the top rear tube of the evaporator. If
installed on first/front pass, it will be too close to the
defrost heater, causing short defrost times which will
lead to incomplete defrost.
Defrost Heater Removal
(736TFI & 736TCI)
The defrost heater is pressed into the evaporator fins.
Heater clips are then hooked from one evaporator tube
to another, over the heater.
To remove the defrost heater, first remove drawers, left
side drawer slides, heat exchanger cover, evaporator
cover and fan shroud, then
1. Disconnect defrost heater electrical leads.
2. Grab the return bend of heater clips with a needle-
nose pliers and pull that end of clip down and away
from evaporator, then unhook other end of heater
clip from evaporator tubing.
3. If needed, cut heater wire near electrical connector
and pull heater from evaporator.
