Why Do My Lights Flicker?
Flickering lights can be a minor annoyance or a symptom of a serious electrical hazard, usually depending on whether the flickering is isolated or whole-house.
Important Safety Warning
A loose neutral connection can cause 240V lines to jump to 415V, destroying all electronics in your home and causing severe shock risk.
Common Signs & Symptoms
- One specific light flickers constantly
- Lights dim briefly when an appliance (like AC) turns on
- All lights in the house flicker simultaneously
- Flickering accompanied by buzzing sounds
Potential Causes
Why is this happening? Here are the most common reasons we see in WA homes:
- Loose lightbulb or faulty fitting
- Incompatible dimmer switch with LED bulbs
- Large appliance pulling significant startup current
- Loose neutral connection at the main switchboard or street
Troubleshooting Steps (DIY Safe)
- 1Turn off the switch, safely carefully check if the bulb is screwed in tight.
- 2If it's a dimmable LED, verify that a modern LED-compatible dimmer is installed.
- 3Notice if the flickers coincide with the fridge compressor or AC starting.
- 4If ALL lights flicker unexpectedly, call an electrician heavily—this indicates a loose neutral which is highly dangerous.
DIY vs Professional
In Western Australia, it is illegal to perform your own electrical work. While you can change a lightbulb or reset a switch, anything involving wiring or removing fittings must be done by a licensed electrician.
