Breaker trips during charging
Usually a circuit sized for the charger's peak rather than continuous load, or a charger set higher than the breaker allows.

Electric Vehicle Charger Troubleshooting and Repairs
Most charger problems we see in Chicago aren't inside the charger. They're in the circuit feeding it: a breaker that's too small for a continuous load, a loose connection that heats up, or an outlet worn out from daily plugging.
Every EV charger repair visit starts with testing the circuit, the connections and the charger's own error codes. Then we tell you what failed and why. If the fault is inside a sealed charger, we'll help you through the manufacturer's warranty process rather than opening it up.
If the original wiring was never right, we'll say so. Our EV charger electrician visits often end with a corrected circuit, not a new charger.
Common failures
Problems We Trace Most Often
Scorched or melted outlet
Heat at a 240-volt outlet points to a loose terminal or a worn receptacle. It needs attention before it becomes a fire risk.
Charger won't power on
We check the breaker, the wiring at both ends and any ground-fault device before blaming the unit.
Slow or interrupted charging
Overheating connections, voltage drop on a long run or a charger configured below the circuit can all slow charging.
Repair or replace
When New Electric Vehicle Charger Installation Makes More Sense
Some chargers aren't worth fixing. When Enel X Way shut down its North American business, JuiceBox chargers lost their app and scheduling features after October 11, 2024. They can still charge, but owners who want scheduling or rebate eligibility often replace them.
ComEd's current rebate rules exclude Enel X and JuiceBox chargers. If you're replacing a unit anyway, check the eligible charger list before you buy.
When the circuit is fine, swapping the charger is usually quick. When it isn't, we fix the wiring first. For bigger electrical problems, see our panel upgrade for EV charger options.

Common questions
Repair Questions
Why does my charger trip the breaker?
Usually the circuit is undersized for continuous charging, the charger is set higher than the breaker, or a connection is failing. Each has a different fix.
Is a warm outlet normal?
Slightly warm can happen under load, but hot, discolored or melted plastic is not. Stop using it and have the outlet and wiring checked.
Do you repair chargers you didn't install?
Yes. We troubleshoot any Level 2 charger circuit in Chicago and nearby suburbs, whoever installed it.
Can you fix the charger itself?
Internal faults in sealed units are usually warranty items. We confirm the wiring is good so the manufacturer can't point back at the install.
Charger Acting Up?
Tell us what it's doing and how it's wired. We'll trace the problem and price the EV charger repair before any work starts.
