As electricians, we get a lot of calls about flickering lights. It’s a common issue that can range from a minor annoyance to a sign of a serious electrical problem. So, if your lights are doing the disco, let’s break down some of the common causes and what you should do.
The Flickering Culprit: Common Causes
- Loose Bulbs or Connections:
- This is often the simplest and most common cause. A loose bulb in its socket or a loose wire connection in a fixture can create intermittent contact, leading to flickering.
- What to do: First, ensure all your bulbs are screwed in tightly. If the flickering persists, it might be a loose wire within the fixture or junction box. Caution: If you’re not comfortable working with electrical wiring, it’s best to call a professional.
- Appliance Overload:
- Large appliances, such as refrigerators, air conditioners, or microwaves, draw a significant amount of power. When they cycle on, they can cause a momentary voltage drop, resulting in flickering lights.
- What to do: If the flickering occurs when a specific appliance turns on, it could be a sign of an overloaded circuit. Consider having a dedicated circuit installed for high-power appliances.
- Dimmer Switch Issues:
- Sometimes, a faulty or incompatible dimmer switch can cause lights to flicker. Certain LED bulbs, in particular, may not be compatible with older dimmer switches.
- What to do: Check the compatibility of your bulbs and dimmer switch. If necessary, replace the dimmer switch with one that’s compatible with your bulbs.
- Problems with the Neutral Wire:
- A loose or damaged neutral wire can cause voltage fluctuations, leading to flickering lights. This is a more serious issue that requires professional attention.
- What to do: If you suspect a neutral wire problem, do not attempt to fix it yourself. Contact a qualified electrician immediately.
- Issues with the Main Electrical Service:
- In some cases, flickering lights can be caused by problems with the main electrical service, such as a loose connection at the service panel or a problem with the utility company’s lines.
- What to do: If the flickering is widespread throughout your home or if you notice other electrical problems, contact your utility company and a qualified electrician.
When to Call an Electrician
- If you’re unsure of the cause of the flickering.
- If the flickering is accompanied by other electrical problems, such as burning smells, sparks, or tripped breakers.
- If the flickering is widespread throughout your home.
- If you suspect a problem with the neutral wire or the main electrical service.
Safety First!
- Always turn off the power at the circuit breaker before working on any electrical fixture.
- If you’re not comfortable working with electrical wiring, it’s always best to call a qualified electrician.
