Why Are My Lights Flickering?
Flickering lights are easy to dismiss, but they should not be ignored when the problem is frequent, affects multiple rooms, happens when major appliances start, or comes with buzzing, burning smells, warm switches, or tripping breakers.
Some flickers come from a loose bulb or incompatible dimmer. Others point to overloaded circuits, loose connections, panel issues, damaged wiring, or utility-side power fluctuations. A licensed electrician can help separate a small fixture issue from a larger electrical concern.
Common Causes Of Flickering Lights
Flickering may happen because a bulb is loose, a fixture connection is failing, a switch or dimmer is not compatible, or a circuit is overloaded. If lights flicker when the AC, microwave, dryer, or other large load starts, the circuit or service capacity may need to be evaluated.
Flickering throughout the home is more concerning than one fixture flickering by itself. Whole-home flicker can point to service equipment, panel connections, utility issues, or other conditions that should be checked promptly.
JCM Expert Insight
JCM Electric looks at where the flicker happens, when it happens, and what else is running in the home at the same time. We check the affected fixtures, switches, circuits, panel condition, and signs of loose or overheated connections. That gives homeowners a clear answer instead of a guess.
Safety Warning
Flickering lights combined with buzzing, heat, burning smells, discoloration, sparks, or frequent breaker trips can be a sign of a serious electrical problem. Stop using affected switches or fixtures and call a licensed electrician.
When To Call A Licensed Electrician
Call JCM Electric if the flickering is frequent, affects more than one room, happens when appliances start, gets worse over time, or appears with any other warning signs. You should also call if an older panel, recent electrical work, or storm damage may be involved.
