Circuit Overload Do your lights sometimes start flickering when you turn on an appliance, such as your dishwasher or microwave? If so, then you might have an overloaded circuit, due to the larger amounts of electrical current which these appliances draw as they startup.
Why do lights flicker when other appliances are on?
Large electrical appliances draw more current as they startup which causes a voltage drop that results in lights going dim or briefly flicker when we turn them on.
What causes lights to flicker in whole house?

Why do my lights dim when I turn on an appliance?
Circuit Overloads
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.
Can a refrigerator cause lights to flicker?
Any time an appliance is plugged in, there is a change in the load in the electrical circuit which causes your lights to dim or flicker. So, a washing machine or refrigerator starting can sometimes cause lights to flicker, but this is not something to worry about.
Can a faulty appliance cause lights to flicker?
As mentioned, infrequent flickering that happens right when a major appliance starts up isn’t usually critical. This can happen in even the best-designed electrical systems, where larger loads have their own dedicated circuits.
Should I worry about flickering lights?
As a general rule, it’s not a good idea to ignore flickering or other variations in your home electrical service. Even if the flickering seems harmless, it could be a sign of a more serious underlying issue with your electrical wiring that could present a dangerous fire hazard to your home.
What would cause lights to flicker and dim in a home?
Sometimes lights flicker and dim because of a loose bulb or a loose connection in the fixture. If the flickering is isolated to a single fixture, it’s usually a straightforward repair. Tighten the bulb and/or turn off the breaker, check the wire connections to the fixture and tighten those connections.
Can flickering lights cause a fire?
Yes, flickering lights can be a warning sign that there is a fire hazard in your home. When lights flicker all over the house and are not associated with a large or major appliance, such as an air conditioner, turning on it could mean that there is an issue with the wiring, which could cause a fire.
What causes multiple lights to flicker?
If multiple lights flicker, this may mean you have loose service conductors in your main electrical panel or meter base. This can happen due to normal wear and tear as your conductors heat up and cool down each time you use them.
How do I fix flickering lights?
Tighten loose bulbs
If your light bulbs are flickering, turn off the power and, using a glove to protect your hand from heat, screw the bulb in more tightly. If a light bulb is in too loosely the socket isn’t making proper contact with the bulb, and that can cause intermittent flickering.
