Electrolux R134A - TEMPERATURE CONTROL AND OPERATION CHECK

2-8
a. If the pointer deflects to the lower
end and remains there, the capacit-
or is shorted and must be replaced.
b. If there is no deflection of the
pointer, the capacitor is open and
must be replaced.
TEMPERATURE CONTROL
The refrigerator has two temperature
controls:
1. Fresh Food Compartment - The fresh
food temperature control senses the
temperature of its compartment and
governs the compressor operation
accordingly.
2. Freezer Compartment - The freezer
compartment control adjusts the
damper door which regulates the
amount of air allowed to enter the fresh
food compartment.
Turning the freezer temperature control to
the coldest settings reduces the flow of
chilled air to the fresh food compartment.
The fresh food temperature control uses a
sensing element that must be cooled suffi-
ciently before stopping the compressor.
The reduced air flow causes longer com-
pressor run time and colder freezer tem-
peratures, while maintaining the required
fresh food compartment temperatures.
Conversely, by turning the freezer tempera-
ture control to the warmest setting, you in-
crease the flow of air into the fresh food
compartment and decrease the flow to the
freezer. This cools the fresh food tempera-
ture control sensing element faster, result-
ing in shorter compressor run times and
warmer freezer compartment tempera-
tures. The fresh food compartment will
stay near the recommended fresh food tem-
perature, unless the freezer temperature is
turned to an extreme temperature. The dif-
ferential between cut-in/cut-out tempera-
ture will vary approximately 10
0
F.
Checking Operating Temperatures
The temperature control feeler tube is lo-
cated in the fresh food compartment. The
feeler tube is wrapped around a thermal
mass located in the back left corner of the
control housing. A small amount of air
passes over the thermal mass which gives
a consistent run time during ambient
changes.
c. If the pointer deflects toward the
high end of the scale and then
slowly returns to the low end,
the capacitor is good.
