You pull into your garage after a long day, plug in your Tesla, and… nothing happens. No charging light, no familiar click, and the Tesla app coldly displays “Charging stopped.” If this scenario sounds familiar, you’re not alone. Thousands of Tesla owners have faced the frustrating “Tesla Charger Not Working” issue at least once — often right when they need their car charged the most.
The good news? In most cases, the problem isn’t serious. Whether it’s a loose cable, a tripped breaker, or a simple software glitch, many Tesla charging issues can be fixed at home with a few quick checks. In this article, we’ll walk you through 10 of the most common reasons why your Tesla charger might not be working — and show you exactly how to troubleshoot each one safely and effectively.
10 Common Causes and How to Fix Them
Loose Power Connection
A loose or unstable power source is one of the most frequent causes of charging problems. If your Tesla charger is not working, the plug may not be fully inserted, or the outlet might be worn or faulty. Even a slight disconnect can interrupt the flow of electricity.
How to fix it:
Unplug your charger and inspect the outlet for looseness or signs of overheating. Plug it back in firmly and make sure the connection feels tight. If possible, try another outlet to rule out a wiring issue. Avoid using power strips or extension cords — they can reduce voltage and cause the charger to stop working.
Faulty Charging Cable
Tesla charging cables are durable, but constant use, bending, or exposure to weather can lead to internal wire breaks or connector damage. When this happens, the vehicle might not recognize the connection or will stop charging mid-session.
How to fix it:
Check the entire cable for cracks, frayed insulation, or bent pins. Try charging your car with another cable if available. If the second cable works properly, the original one likely needs replacement. Contact Tesla Service instead of attempting DIY repairs — doing so can void your warranty.
Tesla Wall Connector Not Configured Properly
If you recently installed a Wall Connector, improper setup could prevent your Tesla charger from working. Incorrect amperage configuration or Wi-Fi disconnection can cause the unit to stop responding.
How to fix it:
Perform a reset by pressing and holding the reset button on the Wall Connector until the LED starts flashing. Reconnect to Wi-Fi and check for firmware updates through the Tesla app. Following Tesla’s installation guide carefully ensures your charger communicates properly with your car.
Overheating Issue
Both the Tesla charger and your car’s onboard charging system have built-in protection against high temperatures. If the connector, plug, or power unit gets too hot, the system will automatically pause charging to prevent damage.
How to fix it:
Unplug the charger and let it cool down for at least 20 minutes. If you’re charging outdoors, move your vehicle or charger to a shaded area. Clean any dust or debris from the vents to improve airflow. Once cooled, plug it back in and check if charging resumes normally.
Software or Firmware Glitch
Software-related bugs can sometimes make it look like the charger is broken — even when it’s not. Updates to your Tesla vehicle or the Wall Connector may cause temporary communication errors.
How to fix it:
Reboot your Tesla by holding both steering wheel buttons until the touchscreen restarts. Afterward, unplug and reconnect the charger. Check your Tesla app for pending software updates on the car or charger, and install them to eliminate firmware conflicts.
Common Reasons Why Your Tesla Charger Is Not Working
Loose Power Connection
One of the simplest but most common reasons your Tesla charger is not working is a loose or unstable power connection. Even a slightly loose plug can interrupt the electrical flow needed to charge your vehicle. Over time, outlets can wear out or wiring can loosen, especially in garages where temperature and humidity fluctuate.
How to fix it:
Start by unplugging your charger and inspecting the outlet or power source. Make sure the plug fits firmly and doesn’t wiggle when inserted. If you’re using a Tesla Wall Connector, check that the wiring inside the electrical panel is properly secured. Try connecting the charger to another outlet to rule out a household wiring issue.
Avoid using power strips, adapters, or extension cords — they can cause voltage drops and create unstable current, leading your charger to shut off automatically for safety reasons. Once the connection feels tight and stable, plug the charger back in and check if charging resumes normally.
Faulty Charging Cable
A damaged or faulty charging cable is another common reason why your Tesla charger is not working. Although Tesla cables are built to last, daily wear and tear, tight bends, or exposure to harsh environments can cause internal wire breaks or connector issues that interrupt power flow.
How to fix it:
Visually inspect your cable from end to end. Look for cuts, exposed wiring, bent pins, or discoloration at the connector tips — all signs of damage or overheating. If the cable looks fine but still doesn’t charge, try using a different Tesla charger or borrow one from a friend to test.
If your car charges successfully with a different cable, the original one is likely defective. Do not attempt to repair it yourself, as tampering can void your warranty or create safety risks. Instead, contact Tesla Service or visit a Tesla Service Center to request a replacement cable covered under warranty.
Tesla Wall Connector Not Configured Properly
If you recently installed a Wall Connector, an incorrect configuration might be the reason your Tesla charger is not working. During setup, the Wall Connector requires the right amperage settings, network connection, and firmware updates to function properly. Even a small error in configuration can stop charging altogether.
How to fix it:
First, check the LED indicator on the Wall Connector. If it’s flashing red or showing unusual colors, that often signals a configuration or communication problem. Press and hold the reset button on the side of the unit until the light flashes, which will reboot the charger.
Next, reconnect the Wall Connector to Wi-Fi using the Tesla app and verify that the firmware is up to date. If you’re unsure about the amperage setup, consult your electrician or Tesla’s official installation guide to ensure the wiring and breaker match the correct rating. A quick reconfiguration or firmware refresh often resolves this issue and gets your charger working again.
Overheating Issue
Overheating is another common reason your Tesla charger is not working, especially if you’re charging in a hot environment or under direct sunlight. Both the charger and your vehicle’s onboard charging system include built-in temperature sensors that automatically pause charging to protect the battery and hardware from heat damage.
How to fix it:
If your charger suddenly stops working, touch the charging connector or plug — if it feels unusually warm, overheating might be the cause. Unplug the charger and allow it to cool for at least 15–20 minutes before trying again. Make sure the charging unit is installed in a shaded, well-ventilated area to prevent heat buildup.
Also, inspect the vents or casing of the Wall Connector for dust or debris that could block airflow. If you consistently experience overheating, your electrical circuit might be overloaded or your charger may need servicing. Regular maintenance and proper placement can help you avoid temperature-related interruptions in the future.
Software or Firmware Glitch
Sometimes, your Tesla charger not working has nothing to do with hardware at all. Instead, it could be a temporary software or firmware glitch that prevents proper communication between your car and the charger. Updates to either system — the Tesla vehicle or the Wall Connector — can occasionally introduce bugs or sync errors that stop charging unexpectedly.
How to fix it:
Start by rebooting your Tesla. To do this, press and hold both scroll buttons on the steering wheel until the central touchscreen restarts. Once the system is back online, unplug the charger, wait a few seconds, and then plug it back in.
Next, check your Tesla app or vehicle settings for pending software updates. Make sure both your car and the Wall Connector are running the latest firmware versions. If the problem persists, you can perform a factory reset on the Wall Connector through its configuration interface. Keeping your software current usually resolves these communication issues quickly and safely.
Circuit Breaker Tripped
If your Tesla charger is not working and there are no lights or signs of power, a tripped circuit breaker could be the culprit. The charger draws a significant amount of current, and if the electrical system detects an overload or surge, the breaker automatically shuts off to protect the circuit.
How to fix it:
Go to your electrical panel and check if the breaker controlling your charger has flipped to the “off” position or is in the middle. Switch it fully to “off,” wait a few seconds, and then back to “on.” If the charger starts working again, the issue was likely a temporary overload.
However, if the breaker trips repeatedly, this could indicate a deeper electrical problem — such as a short circuit, undersized breaker, or wiring defect. In that case, contact a certified electrician or Tesla Service to inspect the installation. Avoid constantly resetting the breaker without understanding the cause, as it can be a safety hazard.
Dirty or Damaged Charging Port
A dirty or damaged charging port is another frequent reason your Tesla charger is not working. Dust, debris, or moisture inside the charging port can prevent proper contact between the charger connector and your vehicle, interrupting the power flow. In some cases, corrosion or physical damage to the port pins may also cause charging failures.
How to fix it:
Inspect the charging port on your Tesla under good lighting. If you notice dirt or buildup, gently clean the area using a soft, dry microfiber cloth. Avoid using liquid cleaners or compressed air, as moisture and pressure can worsen the problem.
If the connector pins look bent, burnt, or corroded, do not attempt to fix them yourself — this could cause further damage. Schedule an appointment with Tesla Service for professional inspection and repair. Regularly keeping the port covered and protected from dust or rain will help maintain a stable and safe charging connection.
Tesla Charger Blinking Red Light
If your Tesla charger is not working and you notice a blinking red light, that’s a built-in error signal from the Wall Connector or Mobile Connector. The number of red flashes indicates a specific fault — such as overcurrent, ground fault, or temperature error — that prevents the charger from delivering power safely.
How to fix it:
Count the number of red blinks on the charger’s LED indicator, then check Tesla’s official troubleshooting guide to identify the exact error code. For example, one red blink might mean a ground fault, while four blinks could indicate a communication failure.
After identifying the code, reset the charger by pressing and holding the button until the light turns off. If the light continues to blink red after rebooting, unplug the charger and contact Tesla Support for professional diagnosis. Avoid repeated resets without knowing the cause, as persistent red signals can indicate an electrical or hardware malfunction that requires attention.
Home Power Supply Problem
Sometimes the issue isn’t with your Tesla or the charger itself — it’s your home’s electrical system. If your Tesla charger is not working, the power supply to your garage or charging station might be unstable, overloaded, or partially disconnected. Issues like voltage drops, blown fuses, or lost electrical phases can all stop charging.
How to fix it:
Start by checking if other devices or lights connected to the same circuit are working properly. If they’re not, your home’s electrical supply may be the source of the problem. Inspect your breaker box for tripped switches or signs of overheating. You can also use a multimeter to test for consistent voltage at the charger’s outlet.
If you notice flickering lights, frequent breaker trips, or inconsistent power, call a licensed electrician to evaluate the situation. In some cases, utility companies can also perform a power quality check to identify external supply issues. Maintaining a stable and dedicated power line for your Tesla charger helps ensure safe, reliable charging every time.
Charger Hardware Failure
If you’ve checked every possible cause and your Tesla charger is still not working, it might be due to an internal hardware failure. Components like the control board, relay, or charging contactor can wear out over time or fail because of power surges, water damage, or excessive heat exposure.
How to fix it:
Examine the charger for any visible signs of damage — such as burn marks, melted plastic, or unusual smells. If the LED indicator shows no light or stays solid red even after a reset, it’s likely a hardware malfunction. In this case, avoid opening the charger or attempting DIY repairs.
Contact Tesla Service to schedule a professional diagnostic. They can determine whether the unit can be repaired or needs replacement. If your charger is still under warranty, Tesla typically replaces defective hardware at no additional cost. Replacing a failing charger with a new one not only restores reliable performance but can also improve safety and charging efficiency.
