EV Charger Repair & Troubleshooting in Las Vegas & Henderson
Charger dead, breaker tripping every time you plug in, or charging far slower than it should? Penny Electric diagnoses EV charger problems across Las Vegas and Henderson — tracing faults to the circuit, breaker, wiring, or charger unit with upfront pricing before repair work.
What Causes EV Charger Problems?
Most EV charger issues are electrical, not a failed car. A tripping breaker, loose NEMA connection, undersized wire, or weak GFCI on the circuit causes won't-charge and slow-charge symptoms that look like a bad charger. Penny Electric tests the full path from panel to connector — and repairs the root cause. This page covers repair and troubleshooting only; for new installs see our EV charger installation service.
This work is part of our complete EV and home energy services for Las Vegas and Henderson — Tesla and Span certified installers, licensed C-2 #74758, permitted and code-compliant.
Signs Your EV Charger Needs Repair
Charger won't power on or show ready status
No lights or error codes often trace to a tripped breaker, loose connection, or failed GFCI — not the charger hardware.
Breaker trips when charging starts
Repeated trips when the EV draws load signal a failing breaker, overloaded shared circuit, or wiring fault — common with older Las Vegas panels.
Charging much slower than rated speed
A 40-amp circuit delivering half speed usually means voltage drop, loose lugs, or incorrect breaker pairing — we measure and fix it.
Intermittent charging or random stops
Heat-related loose connections and worn receptacles cause sessions that start then quit — especially on outdoor installs in desert sun.

EV Charger Repair FAQ
Why does my EV charger trip the breaker?
Usually a failing breaker, an overloaded shared circuit, loose connections at the panel or charger, or undersized wire for the charger rating. We test under load to find which.
Charger won't charge — is it the car or the charger?
We test voltage and continuity from panel to connector. If the circuit is sound, the fault may be in the charger unit or vehicle — we tell you which side failed so you are not replacing the wrong part.
EV charger repair vs. installation?
Installation adds a new 240V circuit and mounts a charger. Repair fixes existing equipment that stopped working — see our EV charger installation page for new home charging setups.
Do you repair Tesla Wall Connectors?
Yes — we troubleshoot Tesla Wall Connectors and other Level 2 brands. Many Wall Connector issues trace to the dedicated circuit or breaker rather than the unit itself.
My charger charges slowly — can that be fixed?
Often yes — slow charging frequently means voltage drop from loose connections, incorrect breaker size, or a circuit shared with other loads. We measure actual delivery amps and repair the electrical cause.
