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.

How to revive a Telechron rotor or General Time M5 rotor (Taken from the March, 1975 edition of Popular Electronics):

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.
