Before testing the fan, unplug the freezer
to avoid an electrical shock hazard.
The evaporator fan circulates air over the
refrigeration coils. The coils absorb heat and the chilled
air is then circulated. If the fan does not operate, the freezer
will not cool properly. The fan motor may have failed, but
check first that something is not simply blocking the fan blade.
The
evaporator fan is located at the back of the freezer. It
may be necessary to remove obstructions such as the contents
of the freezer, freezer shelves, ice maker and the rear inside
panel of the freezer in order to access the fan.
The rear panel may be held in place by retainer
clips or screws. Remove the screws or depress the retainer clips
with a small screwdriver.
Remove any screws that secure the fan or fan
housing so that you can access the fan's wiring. Typically two
screws secure the mounting bracket in place (labeled "A"
below). It may be easier to remove the entire rear panel if the
mounting brackets screws are inaccessible.
