Evaporator Defrost Heater (Model 690)
NOTE: Evaporator fins are sharp and could cause
minor personal injury.
To access and remove the freezer evaporator defrost
heater, the juice can rack, upper front panel, evaporator
front cover, rear duct, lower evaporator cover assembly
and icemaker carriage assembly will need to be
removed first. The heater clips which secure the heater
to the evaporator now need to be removed. Dislodge
the heater clips by pulling the tab of the clip down and
out. Then, extract the screws which secure the evapo-
rator front bracket to the ceiling of the freezer. Pull
evaporator down and rotate it to the right to gain access
to the rear. Then, disconnect the heater electrical leads
from the wire harness and gently pull the defrost heater
from the fins of the evaporator. (See Figure 7-58 & 7-
59)
Defrost Terminator (Model 690)
The defrost terminator is attached to the evaporator out-
let, after the accumulator, at the back side of the evapo-
rator. To access and remove the defrost terminator, first
remove the juice can rack, upper front panel, evapora-
tor front cover, rear duct, lower evaporator cover
assembly and icemaker carriage assembly. Now,
extract the screws which secure the evaporator front
bracket to the ceiling of the freezer. Pull evaporator
down and rotate it to the right to gain access to the
rear. Then, disconnect the defrost terminator wire leads
from the wire harness, and pull the terminator off of the
tubing. (See Figure 7-59)
