*note* For some reason the pictures that go with this paper
will not load. I have emailed Angelfire to find out why. I know my
code is correct so it has to be something else. I'll add them ASAP!
On these pages are diagrams of the more popular refrigerator
defrost drain systems. A defrost drain carries away water that comes from ice
and frost melting off the evaporator during the defrost cycle.

Defrost drains can become clogged. A good indication that a
drain is clogged is water pooling around the bottom of the refrigerator or in
the food compartment. Sometimes condensation will form on the ceiling of the
food compartment indicating that ice has covered the bottom of the freezer
compartment.
To determine if the defrost drain is clogged, remove the cover
from the floor of the freezer compartment. The refrigerator on the left side of
the above diagram shows a "back mounted" evaporator. In this type of
refrigerator you will see a lot of ice frozen to the bottom of the freezer
compartment after removing the floor panel.
The refrigerator on the right in the above diagram shows a
"bottom mounted" evaporator. This type of defrost drain rarely clogs in the
freezer area since the defrost heater is directly above the drain outlet.
However, checking this area is recommended. To check this type of drain, remove
the freezer floor panel and gently remove the insulation under it. Look between
the evaporator coils for any ice buildup near the center of the floor. Inside
this type of refrigerator’s food compartment is a trough mounted in the center
of the ceiling. Water flows from the freezer into this trough and out a drain
line in the back. Remove this trough and check for ice or any type of buildup
that might cause the drain to clog.
The diagram above right shows an older style of draining the
defrost water. In this type of refrigerator the defrost water drains through a
hole in the freezer floor and down the back wall of the food compartment.
Checking this type of defrost system is similar to the others. Remove the
freezer floor panel and check for ice buildup over the drain outlet. Check
inside the food compartment, sometimes under the crisper tray, for the outlet
that finally removes the defrost water from the refrigerator. Make sure the back
wall is clean and clear of obstructions. A dirty back wall or some type of food
or container could cause the water to run off in a direction other than the
desired one.
