TEMPERATURE CONTROL
Temperature control is provided by an adjustable thermostat located behind the control panel es-
cutcheon in the refrigerator compartment. (Fig. 6) This thermostat influences the temperatures in
both the freezer section and the refrigerator section. There is no damper to adjust air flow between the
two sections.
DEFROST HEATER
The defrost heat is provided by a quartz tube radiant heater (Fig. 7) lying underneath the evaporator
coils in the divider mullion. (Fig. 8) A coiled wire element is encased in a quartz tube. Special care
must be taken when handling this heater element to insure that the quartz tube does not come in
contact with any contaminants such as skin oil, perspiration or lubricants. Always wear a pair of clean
gloves when handling the defrost heater assembly. Contaminating the surface of the quartz tube will
cause premature failure.
