Overloaded Circuit Have you noticed that the lights start flickering, blinking or dimming when a major electrical appliance (like your air conditioner or washing machine) comes on? Your problem may be an overloaded circuit—meaning that these appliances are pulling more electrical current than the circuit can handle.
Why do my lights flicker when I use appliances?
Voltage Fluctuations – If your lights flicker when you turn on an appliance with a high wattage, like a microwave, oven, washer or dryer, or the air conditioner clicks on the reason could be because the voltage in your home is fluctuating too much. This could be a symptom of a more serious electrical issue.
Why do my lights flicker when my washing machine is running?
The lights may be flickering when the washing machine is running because there is an issue with the house’s wiring. This may be the result of a loose wire connection, but you could also have undersized wiring, which means the wiring is too slight or too thin to accommodate the amount of power being generated.

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.
Why do my lights flicker when my AC unit turns on?
