As a Tesla owner, the convenience and efficiency of charging your electric vehicle (EV) at home is one of the many perks that come with your investment. However, like any piece of technology, your Tesla Wall Connector can occasionally present issues that need troubleshooting. One such issue that I recently encountered was the green light on my Tesla charger blinking even when it wasn’t plugged into my car.
In this blog post, I’ll walk you through my experience with this problem, the steps I took to diagnose it, and the solutions I found to resolve it. Whether you’re a seasoned Tesla owner or new to the world of EVs, this guide will help you understand and fix the issue of a blinking green light on your Tesla charger.
Tesla Charger Blinking Green When Not Plugged In
When you see a green light blinking on your Tesla Wall Connector, it typically indicates that the charger is in the process of charging your vehicle. However, if the green light is blinking when the charger is not connected to your car, it suggests that something is amiss.
The green light blinking can be caused by several factors, including:
- SSID Broadcasting: A single green light pulsing on the charger might indicate that the Wall Connector is broadcasting its SSID and is ready to be commissioned (source).
- Firmware Update: The Wall Connector might be in the process of downloading or installing a firmware update.
- Internal Fault: There could be an internal fault within the Wall Connector that needs addressing.
Initial Diagnosis
The first step in troubleshooting is to perform a basic diagnosis. Here’s what I did:
1. Check the Connection
I started by ensuring that my Wall Connector was properly connected to the power source. Sometimes, a loose connection can cause the charger to behave unexpectedly. I turned off the power to the Wall Connector at the breaker, checked all connections, and then turned the power back on.
2. Inspect the Charger
Next, I inspected the Wall Connector for any visible signs of damage or wear. This included checking the cable and the connector itself. Any physical damage could potentially cause the charger to malfunction.
3. Reset the Wall Connector
Resetting the Wall Connector can resolve many minor issues. I did this by turning off the breaker that supplies power to the Wall Connector, waiting for about 10 seconds, and then turning it back on. This simple reset often clears temporary glitches.
4. Check for Firmware Updates
Tesla frequently releases firmware updates to improve the performance and functionality of their Wall Connectors. I checked the Tesla app and my Wall Connector settings to see if a firmware update was in progress. If an update is ongoing, the blinking green light might stop once the update is complete.

Advanced Troubleshooting
After performing these initial checks, the green light was still blinking. Therefore, I moved on to more advanced troubleshooting steps.
1. Commissioning the Wall Connector
If the Wall Connector is broadcasting its SSID, it means it needs to be commissioned. Here’s how I did it:
- Connect to the Wall Connector’s Wi-Fi: Using my smartphone, I connected to the Wall Connector’s Wi-Fi network. The network name usually starts with “TeslaWallConnector_”.
- Open the Commissioning Page: I opened a web browser and entered the IP address provided in the Wall Connector’s manual to access the commissioning page.
- Follow the Instructions: The commissioning page guided me through the steps to set up the Wall Connector, including connecting it to my home Wi-Fi network and configuring the necessary settings.
2. Check for Temperature Issues
Sometimes, a blinking green light can indicate a temperature issue. The Wall Connector has built-in safety features to prevent overheating. I checked the ambient temperature around the Wall Connector and ensured it was within the recommended range. Additionally, I made sure there was adequate ventilation around the charger.
3. Inspect Electrical Connections
A rise in plug temperature due to a bad electrical connection between the outlet and the plug can also cause the green light to blink. I inspected the electrical connections to ensure they were secure and free from corrosion or damage. If you’re uncomfortable doing this yourself, hiring a professional electrician is best.
