3. Lights Flicker When It's Windy

What it means: Frayed wiring in the weatherhead (the outdoor fitting where overhead cables from the power line come into the house) is causing a short whenever the cables move.

Code violation? No.

Danger level: High. Aside from the annoyance, the frayed wiring can arc and start a fire.

Solution: Contact the electric utility, which may replace the weatherhead at no charge.
