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

Flickering lights are usually caused by a loose bulb or wiring connection, an incompatible or failing dimmer/switch, an overloaded circuit, or a problem with the neutral or service feed, and you fix them by tightening connections, replacing bad parts, or correcting the circuit issue. Most flicker starts with a loose lamp or a dimmer not rated for LEDs. Our electricians see this daily in the Twin Cities and can tell quickly if it’s a fixture, a circuit, or a panel problem; most fixes are completed in a single visit with truck‑stocked parts.

Use these quick checks and decision signals:

• Snug the bulb and try a known‑good one of the same type; avoid mixing LEDs on old dimmers.
• Toggle or replace a suspect switch/dimmer with an LED‑compatible model if flicker changes when you touch it.
• If a whole room flickers or dims when a big appliance starts, have the circuit load and connections inspected.
• If multiple areas flicker together, have a pro check the neutral at the panel and service connections.

If you notice burning smells, heat at a switch or panel, arcing, or flicker during storms, turn off the breaker and call a licensed electrician. <br/> Updated: 2026-03-12 <br/> Need help in Andover, MN? Call (763) 544-3300 or book online.
