This page covers **circuit breaker repair**: why breakers trip, what it means when one won't reset, the newer AFCI and GFCI breakers, and when the answer is a new breaker versus a bigger fix. ## Why breakers trip A breaker's job is to shut off its circuit before the wiring overheats. A trip is the breaker working. The question is why it's happening. There are three usual reasons: - **Overload.** Too much running on one circuit at once: a space heater, hair dryer, microwave, or window air conditioner on a circuit shared with other outlets. Typically trips after a few minutes of heavy use. - **Short circuit.** A hot wire touching a neutral or another conductor, often from a damaged cord, a failed device, or a nail through a cable. Usually trips instantly, sometimes with a pop or scorch mark. - **Ground fault.** Current leaking to ground, often through water. GFCI breakers and outlets are designed to catch this. ## AFCI and GFCI breakers Newer panels often have **AFCI** (arc-fault) breakers, which detect the arcing that can start wiring fires, and **GFCI** breakers, which protect against shock. The current National Electrical Code calls for AFCI protection on most living-space circuits and GFCI protection in kitchens, bathrooms, garages, outdoors, and other damp locations; Pennsylvania adopts it with its own amendments, so the electrician will know exactly what applies to your job. These breakers trip for reasons a standard breaker ignores: a worn appliance cord, a loose connection, or moisture. A trip on one of them is a reason to look for the cause, not to swap it for a standard breaker. ## When the breaker itself is the problem Breakers do wear out, and some panels are worse than others. Signs the breaker or its connection to the panel needs attention: - It won't reset, or trips immediately with nothing plugged in - It feels warm, or there's a hot smell or discoloration at the panel - It trips at loads it used to handle - It's loose in the panel or doesn't seat firmly - It's in a panel brand inspectors commonly flag, such as Federal Pacific Stab-Lok or Zinsco. See [panel upgrades](https://pennsylvaniaelectricians.us/electrical-panel-upgrade/) ## Never "fix" a trip with a bigger breaker Swapping a 15-amp breaker for a 20, or a 15-amp fuse for a 30, stops the trips by removing the protection. The wire stays the same size and can overheat inside the walls. It's one of the most common unsafe repairs electricians find in older Pennsylvania houses, especially in fuse boxes. The real fix is finding the cause: spreading the load, adding a circuit, repairing a fault, or replacing a failing breaker with the correct one. ## When to call an electrician about a breaker - It trips again after you've unplugged things and reset it once - It trips instantly when reset, with nothing plugged in - It won't stay in the on position - It's warm, buzzing, or there's a burning smell at the panel - Several breakers trip, or lights dim when they do - Fuses blow repeatedly, or someone has installed a larger fuse than the circuit's original ## What breaker repair costs [HomeAdvisor](https://www.homeadvisor.com/cost/electrical/upgrade-an-electrical-panel/) lists replacing a single circuit breaker or fuse at about **$100 to $200**. Finding the cause of repeated trips is often most of the bill, and adding a new circuit to relieve an overloaded one costs more. If the panel itself is the problem, replacement typically runs $518 to $2,193 (HomeAdvisor's June 2026 figures); see [panel upgrades](https://pennsylvaniaelectricians.us/electrical-panel-upgrade/) and the [Pennsylvania cost guide](https://pennsylvaniaelectricians.us/guides/electrician-cost-pennsylvania/). - Whether the cause is the load, a fault in the wiring, or the breaker - Breaker type: standard, AFCI, GFCI, or dual-function breakers cost more - Availability of breakers for older panels - Adding a dedicated circuit for a heater, appliance, or air conditioner - Panel condition and whether replacement makes more sense ## What you can safely do 1. **Unplug** heaters and appliances on that circuit. 2. **Reset once:** push the breaker fully to off, then back on. 3. **If it trips again, leave it off** and call an electrician. 4. **Note what was running** and how quickly it tripped. 5. **Don't remove the panel cover** or replace breakers yourself. ## Questions to ask about a breaker repair - Is this an overload, a fault in the wiring, or the breaker itself? - Should this circuit be split, or should something get a dedicated circuit? - Does this circuit need AFCI or GFCI protection under current code? - Is my panel still worth repairing? - Pennsylvania has no statewide electrician license. Does my municipality require one for this work, and what's your license number if so? What's your PAHIC registration number? ## FAQ **Why does my breaker trip when I run a space heater?** Most likely an overload. A space heater can draw most of what a 15-amp circuit can safely carry, so anything else on the same circuit pushes it over. Run the heater on a different circuit, and if trips continue, have an electrician look at the circuit and consider a dedicated one. **Is it safe to keep resetting a breaker?** Reset it once after unplugging things. If it trips again, leave it off and call an electrician. Repeatedly resetting a breaker on a faulted circuit can cause damage. **How much does it cost to replace a circuit breaker?** HomeAdvisor lists replacing a single breaker or fuse at about $100 to $200. AFCI and GFCI breakers cost more, and finding the cause of repeated trips can add time. **Can I put in a bigger breaker so it stops tripping?** No. The breaker is sized to protect the wire. A bigger breaker lets the wire overheat before anything trips. The fix is to find and correct the cause. **Why does my AFCI breaker keep tripping?** AFCI breakers detect arcing, so they can trip on a worn appliance cord, a loose connection, or some motors and older devices. Unplug things on that circuit to see if one device causes it. If not, an electrician should check the wiring.
