Test Dimmer
Now that the wires are connected we need to test the operation of the dimmer as follows:
  • Turn the power back on at the electrical service panel.
  • Some dimmers such as this Leviton Decora© have an air gap switch which locally controls power to the switch. When pulled out it cuts power and when pushed in it allows power to the switch. Make sure it is pushed in.
  • Press the touch plate or other device to turn the dimmer on.
  • If the lights turn on you are all set to go the the next step.
  • If the dimmer does not work see Section 10: "Troubleshooting" in this tutorial.
