Dimmer Switch Wiring and Ceiling Fans

Electrical Question: I tried to replace a ceiling fan dimmer switch but now it trips the circuit breaker.

  • I removed a ceiling fan and replaced with a new light fixture.
  • During the event I removed a dual pole switch and dimmer switch which were attached to the original fan thinking I could replace that with a dimmer switch only.
  • One other problem is there is a second switch on an opposite wall.
  • I hooked this up as I thought it was originally but now when I turn on power the light is on but one switch does nothing and the second blows the breaker.
  • I am sure I have messed this up but could sure use some help.

This electrical wiring question came from: Robert, a Homeowner from Bloomsburg, Pennsylvania.

Wiring a Replacement Dimmer Switch

Important

  • If a rewired switch is causing a circuit breaker to trip there is most likely a dead short between a neutral and hot wire, a dead short on the wire to the light fixture, or two separate circuits are wired to the same light switch.

Example

  • When rewiring a switch box where there are more than one light switch there may be more than one circuit that supplies power to one or more of the light switches.

Solution

  • Identify all of the circuits preferably before removing the existing light switches.
  • Use a voltage tester to identify the circuits supplying power to the light switches.

Note

  • When replacing light switches do not disturb other wiring groups that are spliced together, especially white neutral wires.
  • You may notice white wires that are connected to a switch, however these are not neutral wires, but rather white wires that are being used for the switch configuration.
  • Please see the wiring diagrams as listed below for a visual understanding.
