Turn off power to the fan at the circuit breaker, and lay down a drop cloth to collect debris. Pop off the fan's cover and remove the screws holding the fan's housing to the ceiling. (With a fan that's screwed directly to a joist, you may need to trim back the drywall to access the screws.) Pull down the motor housing and disconnect the wires.
