Things You'll Need
Drill with screwdriver bit
Hammer or pry bar
That creaking sound in your ceiling might be a sign that it's time to replace that old Nutone bathroom vent. Nutone makes a number of different bathroom vent models; some are simply vents, while others may have such features as lights and heat lamps. No matter which Nutone bathroom vent you may have, the removal procedure is more or less the same. As with any other DIY project, exercise caution while working.
Locate the circuit breaker that controls the power for the Nutone bath vent and change it to the "off" setting. In most homes, this will be in the main circuit breaker panel. The bath vent may be on the same circuit as the lights for the bathroom.
Remove the cover from the Nutone fan by grasping the sides of the fan cover and pulling it straight down to expose the cover clips. Press the clips with your fingers to squeeze them together and pull the cover all the way off the fan.
Press the sides of the housing where the tabs for the blower assembly connect. Pull the blower assembly and housing down, but not all the way, as it will still be plugged into the housing. Lower the blower assembly until you can see the cord from the assembly leading into the housing plug. Pull the blower plug out of the housing.
Slip the junction box out of the housing by pressing the tabs on the sides or unscrewing the cover, depending on your Nutone model. Unscrew the nuts connecting the white and black wires. Test the wires with a voltometer to check that the electricity has been cut correctly. The meter should read "0" if it has.
Remove any electrical tape holding the white and black wires together and pull them apart, cutting them with a utility knife, if needed. Unscrew the copper wire from the green terminal screw. Push the house wire out of the electrical panel so that it is free from the Nutone assembly.
Remove any screws or nails securing the Nutone housing to the ceiling joists. Screws can be unscrewed with a screwdriver or power drill with screwdriver drill bit, while nails can be pried out with a hammer or pry bar.
Pull the Nutone fan unit out of the ceiling space. Slide it away from the duct connection in order to pull it out of the venting. Cut away any cut tape connecting it to the vent work before removing it completely.
