Lights Keep Flickering?

Lights Flickering Throughout Your House?

One flickering bulb is usually the bulb. Lights flickering in several rooms, or dimming when an appliance kicks on, points at a loose connection or a failing panel — and that is worth looking at.

Are Flickering Lights Dangerous?

Short answer: one flickering bulb is usually nothing. Lights flickering in more than one room, lights that dim when the AC or dryer kicks on, or flickering with a burning smell or a warm panel can mean a loose or overheating wire. That is a fire risk, and it is worth having a licensed electrician look at it.

What to do right now

  • Note whether it is one fixture or several rooms at once.
  • Note whether it happens when the AC, dryer or fridge starts up.
  • If you smell burning, or the panel feels warm or buzzes, do not touch the panel. Call us right away.
  • Call us — we answer 24 hours and can usually get out same day.

⚠ WARNING ⚠

Never reset or shut off the main breaker on an old panel

On older panels, especially Federal Pacific, Zinsco and fuse boxes, the main breaker can stick, break or fail to come back on, and your whole house can lose power. If you smell burning, see scorch marks, or the panel feels warm or buzzes, leave it alone and call us right away at (908) 287-2187.

Why Lights Flicker: The 6 Most Common Causes

Loose or wrong bulb

A bulb that is not screwed in tight, or an LED on an old dimmer. Easy fix.

Bad switch or dimmer

Worn switches and dimmers lose contact and make the light flicker or buzz.

Loose wire

A loose wire in a fixture, outlet or switch heats up over time. This is the one that causes fires.

Big appliance starting

Lights dipping when the AC, dryer or well pump kicks on can mean the home is short on power.

Old or full panel

Worn breakers and old panels, like Federal Pacific and Zinsco, can make lights flicker all over the house.

Utility line problem

If neighbors see it too, the issue may be the utility line. Report it to JCP&L or PSE&G first.

When It’s OK and When to Call Today

Usually OK

  • One bulb flickers and stops after you tighten or replace it
  • A quick, tiny dip when a big appliance starts
  • LEDs flicker only on an old dimmer

Call today

  • Lights flickering in more than one room
  • Lights dim a lot when a large appliance starts
  • Flickering that got worse over recent weeks
  • Any flickering paired with a smell, buzzing or a warm panel

Flickering Lights: Quick Answers

Are flickering lights dangerous?

Sometimes. One bulb that flickers is usually just the bulb. Lights flickering in several rooms, lights that dim when a big appliance starts, or any flicker with a burning smell or a warm panel can mean a loose or overheating wire, which is a fire risk. Have an electrician check it.

Why do my lights flicker when the AC or dryer turns on?

A quick, small dip when a big appliance starts can be normal. If the lights dim a lot, stay dim or it keeps getting worse, it often points to a loose wire, an overloaded panel or a weak main line coming into the house.

Why are all the lights in my house flickering?

When lights flicker all over the house at once, the problem is usually at the panel or the main line coming in. If your neighbors see it too, call your utility (JCP&L or PSE&G) first. If it is only your house, call us.

Can an old electrical panel cause flickering lights?

Yes. Old, full or recalled panels, like Federal Pacific and Zinsco, can have worn breakers and loose parts that make lights flicker. A panel upgrade fixes the cause. Most panel upgrades in New Jersey run $2,000 to $7,000.

Why do my LED lights flicker?

LED bulbs often flicker on dimmer switches that were made for old bulbs. Swapping to an LED-rated dimmer usually fixes it. If LEDs flicker with no dimmer, have the wiring checked.

How much does it cost to fix flickering lights?

$229.99 for a service call with a small repair, like one outlet or switch. $259.99 for a service call with initial diagnosis, when we need to find where the problem is. $389.99 for an after-hours emergency call. Bigger repairs are quoted up front before we start.

Can you come out tonight?

Yes. We answer 24 hours a day, 7 days a week, and can usually get a licensed crew out the same day. Call (908) 287-2187.

Charles came today to install an additional outlet in our kitchen. He couldn’t have been more professional. Did a fantastic job. I’m so pleased. He even help us locate our missing newly adopted senior cat. She was upstairs in my closet. Don’t know what we would have done without him today. I can’t say enough about this company. I will always call them for future electrical needs. Best ever.❣️

Spartan Home Pros were fantastic to work with. Mariano took our call and helped us on a Sunday night during what we thought might be an emergency. Al and the team were at our home first thing the next morning to begin work. They were thorough in explaining everything and the work they did came out great. Highly recommend.

I had an outdoor outlet not working and I called late on a Sunday evening. Not only did they answer immediately, they stayed with me on the phone to troubleshoot and make sure there was no danger. They also scheduled a technician to come out first thing Monday. They arrived and did a diagnostic that showed I needed a new outlet installed. The guys did a great job, they were very nice and quick, and the price was great! Thanks!

Mariano came out to help us after we lost power. He answered very quickly and offered reassurance over the phone before he arrived. When he arrived he was extremely professional and helpful. I would definitely recommend this company for future service! In fact we plan to use them for some future projects around the house that we have been planning because our experience was so positive. If you’re looking for a professional, reliable, quick, and compassionate electrician we would definitely recommend Mariano and the whole Spartan team!
