How to Fix a Tesla Wall Charger: Your Comprehensive Troubleshooting Guide

Today, I’m going to show you a quick and easy way to address an issue with your Tesla wall connector. Many owners face problems with the switch and temperature sensor inside the connector, which can lead to malfunctioning. However, there’s a simple workaround to override this issue and get your wall connector working again.

To begin, you’ll need to open up the connector. Carefully unscrew the bottom plate and detach it to reveal the internal components. Inside, you’ll find a PCB with various elements. Locate the dip switches and the rotary switch, which are essential for changing the settings.

The key step is to set the connector into legacy mode. To do this, you’ll need to adjust the position of dip switch 2. By moving this switch to the off position, the connector will no longer require the temperature sensor or the switch to function, effectively putting it into legacy mode.

Next, you’ll identify four pins inside the connector, with two of them related to the switch and the temperature sensor. Remove these two wires, insulate them, and tuck them away as they are no longer needed in legacy mode. Then, reassemble the connector and power it up.

Upon completing these steps, your Tesla wall connector should work like a standard type 2 charger. However, there’s an additional trick to ensure the unit doesn’t throw an error due to the absence of the temperature sensor. By incorporating a 10K resistor connected to a specific pin, you can trick the unit into detecting a stable temperature, resolving any potential error.

Once you’ve made these adjustments, test the wall connector to ensure it’s functioning correctly. With these modifications, you should have your Tesla wall connector up and running smoothly again.

With these simple steps, you can resolve common issues with your Tesla wall connector and have it operational in no time.

Remember that any modifications to the wall connector should be carried out carefully and with caution. If you’re unsure about making these adjustments yourself, it’s always best to seek professional assistance.

How do I fix my Tesla wall connector?

To override the problem with the Tesla wall connector, you can open up the charger and put it into legacy mode, where it will no longer require the temperature sensor or the switch. This should make it start working again. You will need to open the connector, remove six security torque screws, and disconnect a ribbon connector. Then, you can switch dip switch 2 to the off position to put it into legacy mode. Additionally, you may need to check and secure the wires monitoring the phases and the neutral in the connector. Finally, you can use a 10K resistor to trick the unit into thinking that the temperature in the connector is at 20 degrees, thus simulating the presence of a sensor.

What if the Tesla wall connector is throwing errors?

If the Tesla wall connector is throwing errors due to the temperature sensor, you can use a 10K resistor to trick the unit into thinking that the temperature in the connector is at 20 degrees. This will override the error and allow the connector to work as intended.

How can I test if the Tesla wall connector is fixed?

To test if the Tesla wall connector is fixed, set it to the desired amperage and use it to charge a compatible vehicle. If the charging process starts without errors, it indicates that the connector has been successfully fixed.
