Before You Begin
Replacing a range hood is doable for a homeowner who has done extensive electrical work in the past. That's assuming the power for the unit is there and the ducting is already run and in place. The project is a basic swap of an old unit for a newer quieter and more efficient one. The steps provide an overview of what's involved for the most typical type of range hood. Before installing one yourself, carefully read the manufacturer's direction and take the hood apart to study its components. Turn the power off at the service panel and lock or tag the panel so there's no danger of it being switched on accidentally.
Step 1 : Analyze the location
Use the diagram as an overview of how the hood is installed in relation to the duct and wiring. It illustrates how ductwork runs from a roof and how the electrical lines are wired.
Step 2 : Prepare the hood
Take the range hood apart by unscrewing the duct plate from the top of the hood, then remove the filters, the bottom cover and the damper/duct connector and set them aside.
Step 3 : Install the cable clamp
Remove the wiring knock out panel and install the electrical cable clamp.
