Why do my lights dim when an appliance turns on?

If your lights flicker or dim whenever you turn on an appliance (e.g. a washing machine, vacuum cleaner, or microwave) then you’re beginning to overload your circuit. Each home electrical circuit has a limit on just how much power it can draw. The lower current flow leads to dimmer lights in the room.

Why do my lights flicker in my house?

Loose wiring can not only cause flickering lights, but is a leading cause of house fires. Outdated wiring is another top cause of house fires. Loose connections in an outlet, light or switch box can cause arcing, where electrical current “jumps” over gaps in the connection. This is a major cause of electrical fires.

What are flickering lights a sign of?

Flickering lights are the result of a reduction or a fluctuation in total household voltage that results in the lights dimming for a moment. Abrupt changes in voltage from low to high can damage electronics and in rare cases cause an electrical fire.

How do I stop my LED lights from flickering?

Summary – How to stop LEDs flickering

  1. Always drive LED products using an LED power supply that’s designed for the job.
  2. Make sure all your LED products are compatible with the control circuits and power supply you’re using.
