Why does my breaker keep tripping?
A breaker trips for three reasons: the circuit is overloaded, there is a short circuit, or there is a ground fault. Overloads are the most common, usually a space heater, hair dryer, window AC or microwave sharing a circuit with too much else. Unplug everything on that circuit, reset the breaker, and add devices back one at a time. If it trips with nothing plugged in or trips instantly, that points to a wiring fault or a failing breaker that needs a licensed electrician.
- Unplug everything on the circuit, then reset
- Add devices back one at a time to find the load
- Trips instantly with nothing plugged in? Stop and call us
- Never replace a breaker with a larger amp rating

Why is my outlet not working?
Start with the easy checks: a tripped breaker, a tripped GFCI outlet somewhere else in the house (bathroom, kitchen, garage or outside), or a wall switch that controls that outlet. If those are fine, the outlet may have a loose backstab connection, a burned contact, or a broken wire upstream. Dead outlets with no tripped breaker often mean a failed connection in a box on the same circuit, which is something an electrician should trace.
- Check the breaker panel for a tripped or half-tripped breaker
- Press RESET on every GFCI outlet in the house
- Try a switch near the outlet
- Test another device to rule out the appliance

Why won't my GFCI outlet reset?
A GFCI will not reset if it has no power coming in, if there is a real ground fault on the circuit, or if the device itself has failed. First confirm the breaker is on. Then unplug everything downstream, including outdoor and garage outlets that may share the GFCI, and try again. If it resets with everything unplugged, one of the devices is leaking current. If it still will not reset with nothing connected, the GFCI is worn out and should be replaced.
- Confirm the breaker is on
- Unplug all devices on the protected outlets
- Press TEST then RESET firmly
- Moisture in an outdoor box is a common cause in Florida

Why are my lights flickering?
A single flickering light is usually a loose bulb or an incompatible dimmer and LED combination. Flickering across a whole room points to a loose connection at a switch or junction box. Flickering through the entire house, especially when the AC or a large appliance starts, can mean a loose neutral or service connection at the panel or the utility meter, which is a fire and equipment hazard. Whole-house flicker should be looked at promptly.
- Tighten the bulb and try a different one
- Check if the dimmer is rated for LED
- Does it flicker when the AC kicks on? Call us
- Whole-house flicker is a loose neutral until proven otherwise

What should I do if I smell burning from an outlet?
Treat a burning or fishy plastic smell as an emergency. Turn off the breaker for that circuit immediately, unplug anything in the outlet once the power is off, and do not use it again. The smell means wiring insulation or the outlet itself is overheating from a loose or arcing connection. If you see smoke, scorching or flames, leave the house and call 911. Otherwise call a 24-hour electrician to open the box and repair the connection.
- Turn off the breaker right away
- Unplug the device after the power is off
- Do not use the outlet until it is inspected
- Smoke or flames: get out and call 911

Why is my electrical panel buzzing?
A faint hum from a breaker panel can be normal, but a loud buzz, crackle or sizzle is not. It usually means a breaker is failing to trip under an overload, a connection is loose and arcing, or a breaker lug has corroded. Older Federal Pacific and Zinsco panels are known for this. Do not open the panel cover yourself. A buzzing panel that is also warm to the touch or smells hot should be treated as an emergency call.
- Feel the cover for heat (do not open it)
- Note whether the buzz changes when the AC runs
- Turn off large loads and listen again
- Hot, smelly or crackling panel: call 24-hour service

Why did half my house lose power?
Losing power to about half of your outlets and lights while the rest work is the classic sign of a lost leg of your 240-volt service or a lost neutral. Sometimes one of the two main breaker poles has failed, sometimes the utility connection at the meter or weatherhead has burned open. This condition can send 240 volts to 120-volt appliances and destroy them. Turn off sensitive electronics and call an electrician or your utility right away.
- Check whether the main breaker is partly tripped
- Turn off TVs, computers and the AC to protect them
- Look for flickering or unusually bright lights (lost neutral)
- Call us or TECO/Duke for a service-side check
Still stuck? See 24-Hour Emergency Electrician → or call (813) 897-2665.
Why is the power out only at my house?
If your neighbors have power and you do not, check your main breaker first. A main can trip from a lightning surge or a fault and may look only slightly off. Next, look at the meter: if the display is blank, the problem is on the utility side, so call TECO or Duke Energy. If the meter is live but the house is dead, the fault is between the meter and your panel, or the main breaker itself has failed, and that is an electrician's job.
- Switch the main breaker fully OFF then ON
- Check if the meter display is lit
- Blank meter: call your utility
- Live meter, dead house: call an electrician
Still stuck? See 24-Hour Emergency Electrician → or call (813) 897-2665.
Why won't my breaker reset?
Breakers must be pushed fully to OFF before they will latch back to ON, so try that first. If it snaps back off immediately, there is a short circuit or ground fault on that circuit, or the breaker has failed internally. Unplug every device on the circuit and try once more. If it still trips instantly with nothing plugged in, stop resetting it. Repeated attempts against a short can damage wiring. An electrician can isolate the fault safely.
- Push firmly to OFF, then to ON
- Unplug everything on the circuit first
- Trips instantly with nothing plugged in? Leave it off
- Breakers do wear out and can be replaced

Why is my outlet or light switch warm to the touch?
A dimmer switch can be slightly warm in normal use, but a standard switch or outlet should never feel hot. Heat means a loose connection, a worn contact, or too much current through a device that was backstabbed rather than screw-terminated. Turn off the breaker, stop using the device, and have it replaced. Warm outlets in homes with aluminum branch wiring are especially serious and should be inspected by a licensed electrician.
- Turn off the breaker for that circuit
- Move the load to another outlet temporarily
- Look for discoloration or melted plastic
- Aluminum wiring home? Have all devices checked

Why does my ceiling fan wobble or stop working?
Wobble usually comes from unbalanced blades, loose blade screws, or a fan hung from a standard light box instead of a fan-rated box. A fan that stops, hums or runs slowly typically has a failed capacitor, a bad pull-chain switch, or a dead remote receiver. If the fan box is not fan rated, the mount can loosen over time and become a falling hazard. We replace capacitors, switches and receivers, and install proper fan-rated boxes and braces.
- Tighten every blade and bracket screw
- Use a balancing kit for minor wobble
- Humming but not spinning: likely the capacitor
- Check that the box is fan rated, not a light box

Why won't my generator start?
For standby generators, the most common causes are a dead or weak battery, a tripped generator breaker, low oil triggering the shutdown switch, a closed gas valve, or the unit left in OFF instead of AUTO. Portables usually have stale fuel, a clogged carburetor, or a choke problem. Check the controller for a fault code, confirm the battery and oil, and verify the gas supply. If it cranks but will not run or shows a fault, schedule a service visit before storm season.
- Confirm the switch is in AUTO
- Check the battery and oil level
- Make sure the gas valve is open
- Note any fault code on the controller and call us

Why is my EV charger faulting or not charging?
Most EV charger faults trace to a ground fault, a loose or overheated connection at the charger or the plug, a breaker that is undersized for the charger's setting, or voltage sag from a weak circuit. A charger that trips in hot weather or during high-AC afternoons is often on a circuit that cannot hold the load. Check the app or indicator lights for a fault code, try a lower charging rate, and have the circuit and connections checked if it keeps happening.
- Read the fault code in the app or LED pattern
- Reset the breaker once, then try a lower amp setting
- Feel the plug and receptacle for heat after charging
- Faults on hot afternoons point to the circuit, not the car
Still stuck? See EV Charger Installation → or call (813) 897-2665.
Why does my AFCI breaker keep tripping?
Arc-fault (AFCI) breakers protect bedrooms and living areas by detecting arcing from damaged cords or loose connections. They can also nuisance trip on older vacuum cleaners, treadmills, some LED drivers and shared neutrals from improper wiring. Unplug devices one at a time to find the offender. If the AFCI trips with nothing plugged in, there may be a loose connection in a box or a wiring issue that the breaker is correctly catching.
- Unplug devices on the circuit one at a time
- Note if it trips when a specific appliance runs
- Check for a shared neutral on two circuits
- Trips with nothing plugged in: have the circuit inspected

Is it safe to run things on extension cords and power strips?
Extension cords are for temporary use only. Running a refrigerator, space heater, window AC or garage freezer on one full time is a leading cause of home electrical fires. Power strips daisy-chained together or plugged into one another overload a single outlet. If you rely on cords because you do not have outlets where you need them, the safe fix is adding a dedicated circuit or outlet, which is a routine job and far cheaper than a fire.
- Never run heaters or appliances on extension cords
- Do not plug one power strip into another
- Cords warm to the touch are overloaded
- Need permanent power? Add an outlet or dedicated circuit

What should I do after a lightning strike near my house?
Tampa Bay is the lightning capital of the country, and a nearby strike can damage wiring even without a direct hit. After a strike, check for burning smells, tripped breakers, dead outlets, and any scorching at the panel or meter. Unplug expensive electronics until the power is stable. Even if everything seems fine, a strike can leave hidden damage in wiring, surge protectors and GFCI devices. An electrical inspection afterward is worth it, and a whole-home surge protector helps prevent a repeat.
- Smell for burning and look for scorch marks
- Reset tripped breakers once; if they trip again, leave them off
- Test every GFCI and AFCI
- Replace any surge protector that shows a fault light
