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.
Before testing the fan, unplug the refrigerator to avoid an electrical shock hazard.
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.
