What causes flickering lights in my home and how to fix them?

Flickering lights are usually caused by a loose bulb or connection, a failing or incompatible dimmer switch, an overloaded circuit, or a loose neutral, and the fix is to secure or replace the faulty part and correct any wiring or panel issues. The most common cause we see is a loose bulb or an older dimmer not rated for LED lamps. We repair these problems often around the Keystone area, from simple fixture issues to panel-related faults that need a licensed electrician. A quick technician insight: mismatched LED bulbs on legacy dimmers can create a steady shimmer even at full brightness, which disappears once the dimmer is upgraded to an LED-compatible model.

• First checks: tighten the bulb, try a known-good bulb, and bypass or replace a plug-in dimmer.
• If LEDs shimmer, replace the wall dimmer with an LED-rated unit.
• Call an electrician now if multiple rooms flicker, lights dip when large appliances start, or you smell burning or see browning at a panel or outlet.

If lights dim when large appliances start, avoid using that circuit until it’s inspected.
