Repair or replace your electrical panel?
Breakers tripping? Lights flickering? Here is how to tell if a small fix will do, or if you need a new panel.
Quick answer
Swap one breaker if one is bad. Upgrade if the panel is old, hot or too small.
One breaker costs $100 to $200[1]. A new panel averages $1,347[1]. Panels can last about 60 years[2].
Your panel is a safety tool. When it works, you never think about it. When it starts to fail, it can be risky.
Here are the signs to watch, how long parts last, and when a new panel makes sense.
Warning signs
- Breakers trip a lot. The panel may be too small for what you plug in.
- Lights dim or flicker. It can mean loose wires or an overloaded panel.
- Burn marks, heat or buzzing. Call an electrician soon. This can be a fire risk.
- You still have fuses. Old fuse boxes were not built for today's homes.
- It is old. HomeAdvisor lists over 25 years as a sign to upgrade[1].
How long panel parts last
| Part | Typical life | Source |
|---|---|---|
| Service panel | 60 years | Home inspectors[2] |
| Breaker panel, with care | 25 to 40 years | HomeAdvisor[1] |
| Arc-fault breakers | 30 years | Home inspectors[2] |
| Ground-fault outlets | up to 30 years | Home inspectors[2] |
The two sources give different panel lives. A panel in a damp or salty spot may wear out sooner.
Fix it or replace it?
Fix it when...
- Only one breaker is bad.
- The panel is not old, hot or rusty.
- It has room for the circuits you need.
Replace it when...
- You have a fuse box, or an old Federal Pacific or Zinsco panel.
- There are burn marks, heat or buzzing.
- You are adding a big load, like an AC or car charger.
- Breakers trip again and again.
One breaker swap tops out near $200[1]. The average new panel costs about 7 times that. So if just one breaker is bad, a fix is often the smart call.
Stay safe
The U.S. Fire Administration shares these tips[3]:
- Do not overload outlets or power strips.
- Plug big appliances, like a fridge or dryer, straight into a wall outlet. Do not use an extension cord.
- Replace wall outlets if plugs do not fit snugly.
- Have young kids? Use tamper-resistant outlets.
Never open the inner cover of a panel yourself. In Florida, check that your electrician holds a state license[4].

Example: an old fuse box
This example house is made up, but every price in it comes from HomeAdvisor's panel data.
The home has an old fuse box. A fuse blows every time the microwave and the toaster run at once. The owner wants to add a dryer too.
Fixing one fuse spot might cost $100 to $200[1]. But it will not add any power. A switch from fuses to breakers costs $1,500 to $2,000[1].
Since the owner needs more power, a small fix will not solve the real problem. A new panel is the better choice here. If the box were newer and only one breaker failed, the fix would win.
Safe checks you can do
Only look. Never take the cover off the panel. That part is for a pro.
- Read the label on the door. Note the brand and amps.
- Touch the door with the back of your hand. It should not feel warm.
- Smell near the panel. Burning plastic is a warning.
- Write down which breakers trip and when.
What to ask the electrician
- Is this panel safe to keep?
- Is the problem the panel, or the wires in the walls?
- What does a fix cost, and what does a new panel cost?
- How many more years do you think this panel has?
Permits and rules
A new panel usually needs a permit and an inspection. Small breaker swaps may not. Your town decides. In Florida, check your electrical contractor's license on the state DBPR site[4] before work starts.
Mistakes to avoid
- Ignoring a warm or buzzing panel. That is a reason to call soon, not someday.
- Putting in a bigger breaker to stop trips. Never do this. The breaker must match the wire.
- Buying a bigger panel than you need. Ask for a load check first.
- Hiring without a permit. An inspection is a free second look at the work.
A breaker panel can last 25 to 40 years[1] with care, says HomeAdvisor. Home inspectors list a service panel at about 60 years[2][2]. So age alone is not the whole story. How it acts matters too.
What a new panel gets you
A new panel is not just a new box. Here is what changes.
- Fresh breakers that trip the way they should.
- Room to add circuits for new things you buy.
- A label that lists each circuit, so you can find the right switch fast.
- An inspector's look at the work, if your town asks for a permit.
It does not fix old wires in the walls. If those are worn, the electrician will tell you. Rewiring costs $6.00/sq ft to $10.00/sq ft.

Questions people ask
How long does an electrical panel last?
Home inspectors list about 60 years[2] for a service panel. HomeAdvisor says 25 to 40 years[1] with care.
Is a breaker that trips a lot dangerous?
A breaker trips to stop too much power from flowing. If it trips often, call an electrician. U.S. fire departments got about 24,200[3] reports of home electrical fires in 2021.
When is it time to upgrade?
HomeAdvisor lists a panel over 25 years[1] old as one sign. Fuses, scorch marks, buzzing, or not enough room for new circuits are others.
How long do breakers last?
Home inspectors list arc-fault breakers at about 30 years[2] and ground-fault outlets at up to 30 years[2].
Is a buzzing panel normal?
No. A buzz, a burning smell or a warm cover are signs to call an electrician. Home electrical fires caused about 900[3] injuries in 2021.
