Four-way circuit turns on/off randomly
It's either a loose connection, a bad switch, or a poltergeist.


Turn power off to the circuit.
Verify power is off.
Remove the cover plate from each switch.
Remove the screws holding the switches to the box (should be two, one top, one bottom).
Pull the switches out a bit.
Inspect the wiring and connections, looking for loose wires, charred/burnt/melted parts, and any other damage.
Pull the lights down, and inspect the wiring there as well.


If you don't find anything, try replacing the switches. If there are 3 switches controlling the circuit, then you'll need two 3-way switches and one 4-way switch.

If you don't feel comfortable doing this type of work, contact a local licensed Electrician.
