In case anyone else out there is having this issue...

Tesla is having problems with Wall Chargers 3s. I bought mine in April. Almost a month ago, I started getting an error on the LED array... one red flash, then the normal green sequence, resulting in the unit dropping from 32a to 16a. The error code indicates overheating. Tesla support said it was a known issue and they are sending replacements. They said the unit is not overheating, it just thinks it is and throttles the charge rate.

Fast forward to today. I installed the replacement. Any guesses as to what's next? Ding-ding-ding! Correct! Another bad one. Tesla support told me that they thought the issue was resolved, but now know it is not. I'm in queue for a replacement, when they figure out what the cause is.

[sigh]

At least I'm charging at 4KW and can live that way for a while!

:(

Who pays/paid for the labor to replace the Wall Charger?

oh man my suspicion verified! I noticed the red light too a few days ago but didn’t think of it. When my wife told me the car didn’t fully charge this morning, I monitored charging through the app and I saw it drop down from 48a to 24a. My wife took a video and sure enough it blinks three times for high temp detected. I was about to suspect the electrician’s handiwork but your post gave me some guidance. I’ll reach out to Tesla. I decided to go with Tesla and not a third party, and lost rebates. They better fix this. Thanks again.
Btw, odd I see it go to 12kW. Is that normal? I thought it only goes to 11kW.

I am eagerly awaiting my replacement from the one I purchased in June and I’ve been scouring these post to see if the replacement ones were working everyone seems to say they are so I was hopeful but in the back of my head I thought no way they fixed the issue. Keep us updated on the replacement of the replacement...

I'm still waiting but they sent me a return shipping label 2 days ago. I don't know what that is because I'm not sending them my old unit until I get a replacement unit first.

Return label email was 10 days ago. Still no word on the replacement wall connector. I dialed the current down to 24 amps so it will continue charging until the set capacity. Otherwise it stops and unable to proceed unless I unplug and plug it back in.

I'm looking at buying a wall charger, but given this thread a bit nervous about it not working well. If it's only four screws to take out and replace, fine, but if I have to pay for multiple installs well that's a deal-breaker.

Is this really better than at 14-50 outlet? (aside from aesthetics)

You can charge faster with the wall connector, up to 45 mi/hr vs about 30 for the UMC plugged into a 40 or 50A circuit. I don't think that would be much of a factor for most people, full charge in 6hrs or 4hrs, do you really care?

The wall connector charges faster. Also I said that the new units are fixed so if you buy one for Tesla right now, you should have no problem.
