How to Install Wiring for a Range Hood Exhaust Fan

A lighted exhaust fan over the cooking stove or free standing range is a great way to add light to the cooking area and help control the spread of cooking odors and grease through the home, and this would be a great weekend project.

    Hi Doug,
    When providing power to a kitchen for a 120volt stove outlet and exhaust fan the power can be provided from an existing kitchen circuit, or a new circuit is installed. If you are attempting to connect these devices to a circuit outside of the kitchen area then that would be a violation of the NEC electrical code. If the home is older and the circuits in the kitchen area are not grounded then it would be a good time to consider upgrading the electrical wiring and perhaps evaluate the home electrical system for potential improvements.
    Be Safe,
    Dave

    I have run a 110 wire through the wall to an existing wall socket for power to a stove exhaust fan and light. There are only two wires to this plug. Where do I connect the new wires for the fan and light to to get power?

    Thanks!

    Hi F D,
    Your right, the switches on the hood fan should not have gone bad. However check any GFCI outlets in the area to see if one of them may have tripped off. Also check for a tripped circuit breaker at the panel.
    Thanks for sharing your hood fan question with us, I hope this helps.

    I took the range hood fan down to paint. After putting it back up the fan or light will not work. I am pretty sure the wiring is correct. I took pics so I would be sure to get it back right, and wired the black to black, white to white, and then connected the ground wire. Could the switches have gone bad while painting? It doesn’t sound logical.

    Hi Dean,
    If there is only one switch for the range fan that you have then you may have the switch wired right, however there may only be one speed for the exhaust fan. Check the specifications and literature that is supplied with the exhaust fan which will explain the switch functions. The switches of a range exhaust fans are typically pre-wired, the only connections are with the black, white and ground wire.
    I hope this helps,
    Dave

    How do I Wire a Lighted Range Hood Exhaust Fan?
    All I need to do is wire a light and a fan to a Multi-Speed switch.
    When I turn the switch on only the light will come on. When I turn it again only the fan will come on, and when I turn it all the way both the fan and light will come on.

  7. Dave Rongey says:

    Hi Tom,
    That would depend on how far away the outlet is. If the outlet is close by and in the same stud bay of the interior all framing then a wire can be fished up to the location of the hood fan. However, before you do this, you should check to see if you have a 120 volt receptacle outlet behind the range or stove, and if so just fish a wire up from that outlet to the hood exhaust fan. This is the typical method we use to provide power for the exhaust fan.
    I hope this helps,
    Dave
