In this article, we will discuss the whole process about the topic.
Tesla Charger Blinking Red Patterns, Their Meanings and Solutions Explained
The various blinking patterns in red and their explanations are listed below:
1. No Lights
There are a few possible causes for your Tesla charger not to be lit:
- The power source has been shut off. Make sure the charger’s circuit breaker is turned “on” by checking your electrical panel.
- The power is not working. Your Tesla charger won’t work if there is an outage in your neighborhood.
- Incorrectly plugged in the charger. Verify that the charging wire is inserted securely into the charger and that the charger is firmly plugged into the outlet.
- The charger is broken. If you’ve done everything listed above and the light is still off, your charger might be faulty. In this situation, you must get assistance from Tesla.
2. Solid Lights
A Tesla charger’s internal problem is indicated by a solid red light. There are many potential causes for this, including hardware failure, firmware issues, and electrical wiring issues.
Restarting the charger may be able to fix the problem in some circumstances where it is small. Other times, though, the issue can be more severe and call for a new charger.
Turning off the electrical circuit that feeds electricity to your Tesla charger should be your first course of action if you notice a solid red light on the charger. After waiting for 30 seconds, reactivate the circuit breaker.
You should get in touch with Tesla assistance if the charger’s solid red light persists even after being restarted.
3. One Red Blink
A Tesla charger’s single red blink could be a ground fault. This could be brought on by a number of things, including:
- A faulty charging cords.
- A busted car charge port
- An issue with the power lines in the garage or another location where the charger is located.
- Entry of water into the battery or electrical wiring.
The first thing you should do if you notice one red blink on the charger is to look for any evidence of damage by checking the charger cable, car charge port, and electrical wiring.
Avoid using the charger if you notice any damage. Instead, get in touch with Tesla support for more guidance.
4. Two Red Blink
A different issue than one red blink is indicated by two red blinks. The charger was disabled due to a ground assurance issue and significant ground resistance.
- Examine the Wall Connector to make sure it is correctly grounded.
- To operate properly, the upstream power supply’s Bottom connection must be bonded.
- The junction boxes, electrical panels, and wire box terminals are just a few of the physical connections to double-check.
- Check the bond between the neutral and ground conductors at the main panel of residential power supplies.
If you’re linked to a stepdown transformer, get advice on bonding the ground connection from the transformer’s maker.
5. Three Red Blink
A Tesla charger’s three red blinking lights show that charging has been stopped due to a high temperature. This security measure guards against damage to both the charger and the car.
You can try a couple of different techniques to fix this problem:
- Check for excessive warmth in the cable handle and faceplate. Unplug the charger if it feels warm to the touch and get in touch with Tesla support for more help.
- Launch the charger again. To accomplish this, hold down the switch on the charger’s front for 10 seconds.
- When the temperature is lower, consider charging your Tesla car at an alternative time of day.
- You might try adjusting the charge frequency to a lower setting if you are employing a Tesla Wall Connector.
If you have attempted the aforementioned solutions and the three red light flashes are still occurring, you should speak with a licensed professional to have the charger evaluated.
The electrician can check to make sure the connector block is torqued to the appropriate specifications and that the wires utilized in the charger are the appropriate sizes.
6. Four Red Blink
Four red blinks, thankfully, only indicate a problem with internet access.
- Look around the surroundings for anything that can weaken the Wi-Fi signal.
- Verify the local Wi-Fi router’s functionality.
- If the Wi-Fi password has recently changed, upgrade the Wi-Fi settings by following the commissioning procedure on your mobile device.
7. Five Red Blink
Five Red blinking Indicates a Power sharing problem. As a result, the charger can’t interact with any additional Tesla chargers connected to the same circuit. There are several causes for this, including:
- Unreliable Wi-Fi signal
- The router has a problem
- an issue with the charger’s firmware
- the wiring is broken
You might attempt the following solutions to troubleshoot this problem:
- Inspect the Wi-Fi signal’s amplitude close to the charger. Consider placing the charger near the router if your connection is spotty.
- Shut down the router.
- Verify if the charger’s firmware has been updated. Install any updates if they are available.
- You can attempt to reset a Tesla Wall Connector by holding down the button on the exterior of the charger for ten seconds at a time.
- Try linking to a separate charger if you have to use a public Tesla charging.
- If you have a Tesla charger in your home, you might want to try restarting the electrical panel.
For more help, if you’re still having issues, get in touch with Tesla support.
8. Seven Red Blinks
On a Tesla charger, seven red blinks signify car overcurrent. This indicates that an excessive current has been detected by the charger. There are several causes for this, including:
- A battery issue with the vehicle.
- the charging system of the car is malfunctioning.
- Irregularities with the charger.
You could try the following to solve this problem:
- Reduce the charge current setting on the car. The touchscreen in the car lets you accomplish this.
- Record the vehicle’s VIN and the approximate time of the incident and get in touch with Tesla if the problem persists and the attached car was made by Tesla.
- To contact Tesla for support, go to Tesla.com/support/contact. You can also dial (877) 961-7652 or (888) 765-2489.
