Top Reasons Your Home EV Charger Stopped Working
When your home EV charger stops working, the problem almost always traces back to one of these causes.
- Tripped Circuit Breaker. Level 2 home chargers draw 24 to 32 amps continuously on a 240-volt dedicated circuit. If the circuit is overloaded or the breaker is undersized, it trips and the charger shuts off.
- Tripped GFCI. Many home EV chargers are installed on GFCI-protected circuits. A ground fault or minor wiring irregularity can trip the GFCI and cut power entirely. Check for a tripped GFCI outlet or breaker before assuming a larger problem.
- Loose Electrical Connections. Wiring expands and contracts with heat cycles. Connections that were not properly secured at installation can loosen over time, interrupting consistent power flow. This is a common finding when we inspect circuits for homeowners whose EV charger worked then stopped without an obvious cause.
- Charger Hardware Failure. If your charger powers on but the vehicle receives no charge, internal electronics or thermal protection components may have failed.
- Vehicle Communication Error. The charger and vehicle exchange a pilot signal before charging begins. A damaged cable, firmware issue, or fault in the car’s onboard charger can prevent the session from starting or cause it to stop mid-charge.
Not sure what your charger is actually telling you? The table below:
- maps the most common symptoms (what you’re seeing or hearing)
- to the most likely cause,
- and the right first move.
| What you're seeing | Most likely cause | First action | Next step |
|---|---|---|---|
| No power at all No lights, no response from the unit | Tripped circuit breaker or tripped GFCI | Check panel for tripped breaker; check for a tripped GFCI outlet near the charger | DIY first |
| Powers on but car won't charge Lights active, no charge session starts | Vehicle communication error, damaged cable, onboard car charger fault, or charger authorization issue (app or account) | Re-seat the plug firmly; inspect cable for damage; check charger app for authorization or network error; check vehicle for fault codes | Check car and app |
| Stops mid-charge Session started normally then cut out | Breaker trip under sustained load, charger thermal protection activated, or scheduled charging override in app | Check panel for tripped breaker; check app for scheduled session settings; attempt reset; note if it happens repeatedly | Call RES if it repeats |
| Breaker or GFCI trips repeatedly Trips again after every reset | Undersized breaker, overloaded or shared circuit, ground fault, moisture intrusion, or improper grounding | Do not keep resetting. A repeating trip indicates a real electrical fault, not a fluke | Call RES |
| Indicator light flashing amber or red Fault or standby pattern on the unit | Hardware fault, GFCI trip, or ground fault. Note that flashing amber on some brands simply means standby or scheduled delay, not a fault | Check for tripped GFCI; attempt full reset; consult charger manual or app. The specific pattern identifies the fault. | Reset first |
| Charging slower than expected Car charges but takes much longer than normal | Vehicle charge rate settings, normal battery taper as it approaches full charge, or scheduled charging delay. Loose wiring is a secondary possibility if slowness is new and consistent. | Check vehicle charge settings and app; confirm no scheduled delay is active; if slowness is unexplained and persistent, a circuit inspection is warranted | Check car first |
| Heat, burning smell, or discoloration Warmth at the outlet or wall — slight warmth on the charger body during a long session can be normal | Loose connection generating resistance, arcing, or overheating (all fire hazards) | Stop using the charger immediately; do not reset or continue charging | Call RES |

How to Safely Troubleshoot an EV Charger Not Working at Home
These steps apply to most Level 2 home chargers including ChargePoint, Tesla Wall Connector, JuiceBox, and Wallbox.
- Check the circuit breaker. A tripped breaker sits between ON and OFF. Reset it by switching fully to OFF first, then back to ON.
- Check for a tripped GFCI. Press the RESET button on the outlet or GFCI breaker to restore power.
- Inspect the cable and connector. Look for damage, bent pins, or debris that could interrupt the pilot signal.
- Confirm the plug is fully seated. A partially seated connector will prevent the session from starting.
- Read the indicator lights. Solid green typically means active charging. Flashing amber or red indicates a fault. Consult your charger’s manual or app for your model’s specific pattern.
Do not open the charger housing or work inside the electrical panel. EV charger circuits operate at 240 volts and require a licensed electrician to diagnose safely.
How to Reset a Home EV Charger
- Unplug the charging cable from the vehicle
- Switch the dedicated circuit breaker to OFF and wait 30 seconds
- Switch the breaker back to ON
- Allow the charger to complete its startup sequence
- Reconnect the cable and wait for the session to initiate
For smart chargers like ChargePoint, JuiceBox, and Wallbox, a reset option is also available through the companion app. For Tesla Wall Connector, hold the button for 10 seconds until the LED bar flashes.
If the EV charger stopped working again immediately after the reset, the cause is in the circuit or equipment, not something a reset will fix.
When to Call a Licensed Electrician for an EV Charger Not Working
Call a licensed electrician when you notice any of the following:
- The breaker trips every time charging begins
- The EV charger keeps stopping consistently after a few minutes
- The charger powers on but the vehicle receives no charge
- The outlet, wiring, or charger housing feels warm to the touch
- The GFCI trips repeatedly without an obvious cause
- You notice a burning smell or discoloration near the outlet or panel
These symptoms indicate an overloaded circuit, undersized wiring, or a deteriorating connection, conditions that create a fire risk if left unaddressed.

Why Proper Installation Prevents Most Home EV Charger Problems
Most recurring EV charger problems trace back to installation errors, not defective equipment. The National Electrical Code requires EV charger circuits to be dedicated, properly sized, and rated at 125% of the charger’s continuous current draw, standards that are only verified when installation is permitted and inspected. The most common mistakes we see in the field are undersized wire gauge, incorrect breaker sizing, shared circuits, and improper grounding, any of which can cause a home EV charger to stop working under sustained nightly load.
If your charger was installed without a permit, the circuit was likely never verified against code requirements.
How to Prevent Your EV Charger from Stopping or Failing
- Install on a properly-sized, dedicated circuit by a licensed electrician
- Verify wire gauge and breaker size match the charger’s continuous load rating
- Confirm your home’s electrical panel has sufficient capacity before installation
- Inspect the cable and connector periodically for wear or corrosion
- Schedule an electrical inspection if your home’s wiring is older than 20 years
If your EV charger stopped working more than once and resetting the breaker temporarily restored it, that pattern points to a circuit problem that needs professional attention, not another reset.
How Residential Electrical Services Diagnoses an EV Charger Not Charging
When a homeowner in Pearland calls because their EV charger stopped working, we follow a consistent process to find the actual cause rather than guessing.
- We inspect the electrical panel and the dedicated breaker.
- Next, we test the circuit under load, check all wiring connections and grounding, and evaluate the charger equipment itself.
- Then, we walk you through exactly what we found and what it will take to fix it.
Sometimes the answer is a simple connection repair. Other times the circuit needs to be upgraded to handle the charger’s actual load requirements. Either way, you will know what the problem is and what the fix costs before we do any work.
FAQ: Home EV Charger Not Working
Why did my EV charger stop working suddenly?
Why did my EV charger stop working suddenly?
The most common causes are a tripped breaker, a tripped GFCI, a loose wiring connection, or a charger hardware fault. If the breaker or GFCI reset does not restore charging, the circuit or equipment needs professional inspection.
Why does my EV charger keep stopping mid-charge?
Why does my EV charger keep stopping mid-charge?
Repeated mid-session shutoffs usually mean the circuit is overloaded, the breaker is undersized for the charger’s load, or the charger’s internal thermal protection is activating due to a wiring problem. This pattern should not be ignored.
Why is my EV charger plugged in but not charging?
Why is my EV charger plugged in but not charging?
This can mean the vehicle-to-charger communication handshake failed, the onboard charger in the vehicle has a fault, the cable connector is damaged, or the charger’s internal electronics have failed. If the indicator light shows a fault code, check the manufacturer’s guide for that specific pattern.
How do I reset my EV charger?
How do I reset my EV charger?
- Unplug from the vehicle
- Switch the dedicated breaker off and wait 30 seconds
- Switch it back on.
For smart chargers, check the companion app for a reset option or look for a physical reset button on the unit. If the charger faults again immediately, the issue requires a professional diagnosis.
What is the lifespan of an EV charger?
What is the lifespan of an EV charger?
Most quality Level 2 home chargers are rated for 10 years or more under normal use. Premature failures are often caused by installation issues (incorrect wiring, an overloaded circuit, or exposure to moisture), rather than the charger simply wearing out.
Do EV chargers require a dedicated circuit?
Do EV chargers require a dedicated circuit?
Yes. Level 2 chargers require a dedicated 240-volt circuit. Sharing a circuit with other appliances is one of the most common causes of repeated breaker trips and inconsistent charging.
Can an EV charger overload my home's electrical panel?
Can an EV charger overload my home's electrical panel?
It can, particularly in older homes. If your panel is already near capacity, adding a 40-amp or 50-amp EV charger circuit may require a panel upgrade. An electrician can evaluate your panel’s available capacity before installation.
