DEFROST HEATER REPLACEMENT

There are 2 heaters installed in the evaporator
compartment. Evaporator heater and drip pan
heater. The function of the evaporator heater
is to melt the ice built in the fins.
The defrost heaters are firmly embedded in
the evaporator and held in place with spring
clips. To remove the heater: first remove all
spring clips and pull the defective heater out
of the slots in the evaporator, starting at the
wire supply lead.
The replacement heater should be firmly seated
in the slots by using a small block of wood
and a mallet. After the new heater is in place,
replace all the spring retaining clips to assure
heater retention. One lead of the defective
heater may be used to pull the new leads
through the cabinet to the respective terminals
as marked on each lead.
NOTE: Care must be taken to ensure the drain
stub is correctly inserted in the cabinet drain
tube for proper drainage.

are located 2 of each side, the rest in the
door side (front).
