What Is EV Charger Repair & Maintenance?
It's diagnostic and corrective electrical work on installed EV charging equipment: tracing why a charger won't power on, fixing circuits that trip under load, resolving slow-charging issues caused by incorrect amperage settings or degraded connections, repairing storm-damaged outdoor units, and restoring Wi-Fi/app connectivity on smart chargers. Maintenance is the preventive side — periodic inspection of connections, torque checks, firmware updates, and cleaning — that keeps a charger running reliably for years.
Here's what most owners don't realize: the majority of "charger problems" aren't the charger. They're the circuit — a loose neutral, a failing GFCI breaker, a receptacle overheating under continuous load, undersized wiring from a sloppy original install, or surge damage from one of Central Florida's famous afternoon storms. A real diagnostic checks the whole chain from panel to plug, not just the box on the wall.
When Charging Stops Working
The symptoms are consistent: the charger worked fine for months, then the breaker started tripping mid-session. Or charging speed quietly dropped from 40A to 16A and nobody noticed for weeks. Or the unit went completely dark after a thunderstorm rolled through. Or the smart features — scheduled charging, usage stats — died when the Wi-Fi dropped, and the charger never reconnected.
The frustrating part is misdiagnosis. Owners replace an entire charger when the fault was a simple breaker. Or they live with slow charging for a year because the original installer set the internal amperage wrong and nobody checked. Breaker-tripping gets "fixed" by swapping to a bigger breaker — which doesn't fix an overloaded circuit, it just removes the safety device. Every one of these is an electrical problem wearing a charger costume.
Diagnose the Chain, Fix the Cause
Our repair process starts at the panel and works outward: breaker condition and sizing, conductor integrity, connection torque, grounding, GFCI behavior, receptacle condition (for plug-in units), then the charger itself — fault codes, internal amperage settings, firmware, and connectivity. We fix what's actually wrong, verify the repair with a loaded charging session, and tell you plainly if the unit itself is done and needs replacement.
For maintenance, an annual check covers connection torque (copper relaxes over time under thermal cycling), enclosure and cable condition, firmware updates, and a test charge — smart preventive care for equipment that runs high current for hours daily.
How It Works
1. Describe the symptom
Call with what's happening: dead unit, tripping breaker, slow charging, fault light color, or connectivity issue. The symptom often points straight at the cause.
2. Full-chain diagnostic
A licensed electrician tests the circuit from panel to charger — breaker, wiring, connections, grounding, and the unit itself — and identifies the actual fault.
3. Repair and verification
We repair the fault (breaker replacement, re-terminated connections, corrected amperage settings, receptacle replacement, storm-damage repair), then verify with a real charging session under load.
4. Prevention notes
You get a plain-English explanation of what failed, why, and what to watch for — plus maintenance recommendations so it doesn't repeat.
Common Faults We Fix
| Symptom | Usual cause |
|---|---|
| Charger completely dead | Failed breaker, tripped GFCI, loose feeder connection, surge damage |
| Breaker trips mid-charge | Overloaded circuit, failing breaker, overheating receptacle, wrong breaker size |
| Charging much slower than before | Amperage setting changed/reset, one phase dropped, degraded connection |
| Fault/error light on unit | Ground fault, overheating, internal relay failure — read the code, trace the cause |
| Smart features offline | Wi-Fi dropout, outdated firmware, failed network module |
| Burning smell / warm outlet | Loose or corroded connection — stop using it and call immediately |

How often should my EV charger be professionally inspected?
Keep it simple: once a year, have an electrician check connection torque and inspect the cable and enclosure for wear or heat damage; keep the unit's firmware updated; keep the charging cable off the ground and out of standing water; and after any major lightning storm, confirm the charger powers up and charges normally. Five minutes of attention prevents most failures.
Why does my breaker keep tripping after installation?
The common causes: the circuit is genuinely overloaded (charger amperage set higher than the circuit supports), the breaker itself is failing, a GFCI breaker is nuisance-tripping on a plug-in setup, or a connection is overheating and the thermal trip is doing its job. "Just put in a bigger breaker" is never the answer — the diagnostic finds which one it actually is.
Why is my EV charging slower than expected?
Usually one of three things: the charger's internal amperage setting got reset or was configured wrong at install, the car itself is limiting charge rate (check the vehicle's charge settings — many default below maximum), or a degraded connection is dropping a phase. We check all three in order during a diagnostic.
Can you repair a charger that another electrician installed?
Yes — a large share of our repair calls are exactly this. We diagnose the full installation as-found: circuit sizing, breaker, wiring, connections, and the unit. If the original work has code issues (undersized wire, wrong breaker, skipped permit), we'll document them and give you a straight path to making it right.
My smart charger lost Wi-Fi and won't reconnect — can that be fixed?
Usually, yes. The fix sequence: power-cycle the charger, confirm your home Wi-Fi is stable at the charger's location (garages are notorious dead zones — a mesh node or extender often solves it permanently), update firmware, and re-run the charger's network setup. If the network module itself failed, we assess whether a module replacement or unit replacement makes sense.
My charger won't power on at all — what should I check before calling?
Check the breaker first — is it tripped? Reset it once; if it trips again immediately, stop and call. Check whether the unit has any status lights at all (no lights = no power reaching it, which points at the circuit). Note any recent storms — surge damage is common in Orlando. Don't open the charger or the panel yourself; 240V circuits are not DIY territory.
