Replacing the Fan:
Reverse the above steps (1 - 4). Make sure the fan wires and the ground wire are reattached.
Hint for pushing fan down onto pins - rub a bit of dish soap on the grommet so it will slide more easily onto the pin. Check to make sure the fan is seated properly on the pins - try to move the fan back and forth, there should be no noise, if there is check that the grommets haven't come loose.
