    • Many NuTone clocks use Telechron rotors (with the exception of the K-35 that uses a Hansen Synchron motor). The following information can help you get your clock running again.

    Notes for the above method:

  • Instead of using 3-in-1® oil, use proper clock or sewing machine oil
  • Instead of using an ice cube or freeze spray on the last cooling, let the rotor cool naturally
  • If you need more information & tips for the above method, click here
  • If you don't want to try it yourself, you can buy a rotor or send yours to get fixed. click here

    If you have a K-35 with a Hansen Synchron motor, you may be able to buy them here or here.


    Electric Clock Safety:

    Electric clocks can be dangerous, especially if their cords or wires are frayed or damaged. Here are some steps to keep your clock from burning down your house.


  • Make sure all internal wiring is in good shape. If it isn't, replace the wiring or have someone do it for you.
  • If the clock is being used in a wet/industrial/outdoor enviroment, plug the clock into a GFCI (Ground Fault Circuit Interupter) protected outlet.
  • When buying new cords, plugs, etc. make sure the UL mark of Underwriters Laboratories is on it. This means that it has been tested & approved for use.
  • When re-wiring a clock or any appliance, make sure to tie a strain relief knot in the cord where it enters the clock or appliance.
  • When wiring a new plug to a clock or appliance, use either a Quick Clamp/Automatic Wiring/Easy-Wire plug for 18 AWG wire, or a round/rectangular plug with an underwriters knot as a strain relief. Click here for how to wire an underwriters knot.
  • When wiring a new cord to a clock or appliance, DO NOT USE ANY SMALLER THAN 18 AWG WIRE! Most electric clocks, lamps, and other small appliances use ~2-7 watts, so an 18 gauge cord is acceptable.

    Wire Gauge Normal Load Capacity Load
    18 5 Amps (600W) 7 Amps (840W)
    16 8.3 Amps (1000W) 10 Amps (1200W)
    14 12.5 Amps (1500W) 15 Amps (1800W)

    [NOTE: THIS IS MY PERSONAL PERSPECTIVE ON SAFETY, IF YOU WANT A PROFESSIONAL OPINION, CONTACT AN ELECTRICIAN!]


    To Wire a Chime or Doorbell:


    To wire a doorbell, follow this diagram. However, most NuTone doorbells & doorchimes use 16 Volt transformers.

    Connect the wire(s) from the transformer to the transformer terminal, and the wire(s) from the pushbutton(s) to the Front & Rear terminals on the chime.
