Caution:
Please read our safety
information before attempting any testing or repairs.
Before
testing the defrost heater, unplug the freezer to avoid an
electrical shock hazard.
The
defrost heater 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.
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.
There
are three primary types of defrost heater elements; exposed
metal rod, metal rod covered with aluminum tape or a wire
coil inside a glass tube. All three elements are tested in
the same way.
