Resolved: Tesla Wall Connector Overheat Issue - In case it helps anyone

My experience in case it helps anyone. I had the Tesla Wall Connector 18FT installed around August 2021. Had no issue until early May 2022. I plugged it in and saw the red lights on the charger, and the car wouldn’t charge. The Tesla in car dashboard said the charger was overheating. It was not a particularly hot day. Certainly had much hotter days previously. Also hadn’t used the charger since the previous day, so that wasn’t it.

I googled a bunch of stuff and stumbled upon this and other posts. Other posts also said that it is potentially a known defect with certain wall connectors and Tesla will replace under warranty without issue. Before calling Tesla, I spent some time doing the on/off circuit breaker thing. I even got a cold damp cloth and wrapped around the wall unit/charging handle, just in case it was actually overheating. It wasn’t.

When I called Tesla support, they were quickly receptive to it and explained they would first push through a firmware update and see if that would fix it. I believe they said to wait six hours or so. I waited about eight hours and connected to the wall connector 192.168 thing per the instruction manual and confirmed I had the latest software version. They would also send me an email at the same time asking for certain pictures to get the unit replaced under warranty if that did not work. They wanted pictures of the wall connector, charging handle, electric box circuit breaker, and a pic of the wall connector with the faceplate taken off so they could see the wiring done behind it. I thought I needed an electrician to come back and install, but really, the electrical stuff didn’t need changing. I just had to unscrew four screws and replace the wall unit that slips right into the wiring backplate that stays on the wall. Super easy.

I sent the pictures via email and followed up two days later. The person said they didn’t get the email. I forwarded to a new email and she said it is now in processing. I followed up two days later and a new person told me the previous person didn’t finish the request, and now this guy did it. This person informed that I would receive an email within 1-2 days with an order confirm for a brand new wall connector unit, and within 1-2 days after that, I would get the FedEx tracking number. Each time I spoke to a Tesla rep, I asked for expedited shipping. I explained that we are a Tesla only household, and trickle charging sucks. After speaking with the third person, I got the order confirm the next day and the FedEx tracking number the day after that, like the guy said. Unfortunately, it was not expedited. Altogether, from the day it broke and I called Tesla, I got the new unit in hand two weeks later. No real complaint except that it shouldn’t have taken three calls, and they should have expedited (I even offered to pay for the expedite fee). The new unit was the 24FT long cable that they currently sell on the online store. I was really happy with that, the extra 6FT really helps reach spots on our driveway for charging.

Hope this helps.
 
Same here. Took about 11 business days from call to delivery. I told them I read the manual and performed all troubleshooting steps and verified I had the latest firmware. They connected to it remotely and then approved the warranty replacement. No photos, no disassembly, easy peasy.
I did however give them feedback that just like Tesla gives Uber credits at a Service Center for warranty repairs, they should provide free supercharging between the warranty approval date and delivery date of replacement wall connector. I’ll keep dreaming…
 
I had the same issue happen on my Gen 3 wall charger: red light flashing 3 times last night and car would not charge. Leading up to this, my charger started to show one flashing red light, followed by the green stream, when charging, but this wasn't consistent for every charging session, meaning some charging sessions would show the normal green stream when charging.

Called Tesla Wall Charger support and after some troubleshooting steps per the online web page, that I had also tried before calling, the agent had me manually download and reinstall the latest firmware on my wall charger, which as I type this, is 22.7.0. When that changed nothing, they did a couple of more checks and said my charger had an issue and needs to be replaced.

The agent put in the replacement request and it should arrive in 11 days. Once it gets here, I'll need to replace the face plate (seems easy enough per the instructions) and send back the old one.

Until then, I'll be trickle charging when parked at home.

Happened to me too. Seems the first batch of 3rd gen HPWCs had a manufacturer’s defect. My replacement has worked fine ever since installation.
I still think that when a HPWC has a warranty issue, Tesla should provide supercharger credits (until delivery of the replacement) the same way they issue Uber credits when dropping off car at SC.
