The fan is connected by two or three wires.
Label the wire placement on the fan before disconnecting the
wires. The wires are connected to the fan with slip-on connectors.
Firmly pull the connector off (do not pull on the wire) of
the fan's terminal. You may need to use a pair of needle-nose
pliers to remove the connectors. Inspect the connectors for
corrosion. If the connectors are corroded they should be cleaned
or replaced.
Remove the fan blade from the old motor and
place it onto the new fan motor. The blade made be held in
place with a spring or "C" clip. Use a small slot
screwdriver to pry off the clip.
Replace the fan onto the mounting
bracket and back into the fan housing. Spin the fan to make
certain it can turn freely. Replace the rear freezer panel
and plug in the refrigerator.
