I have a 3 year old HPWC, er wall connector and it's worked fine for all this time. Suddenly it is often failing. Insert cable into car ... RED. Have to reset the button to the right side of unit. History: Installed in prior garage for 2 years. Fine. Disconnected. Moved to new garage. Been in for 9 months. Installed by qualified spark. Just started failing in the past week. What's new in past week? Added a split duct A/C unit in garage. It is fed off same panel. No breakers tripping. Added a Big Ass LED light. VERY bright. Here's the weird thing. A couple of times it trips when I enter the garage from side door and trip the LED motion sensor. But the LED was in old garage too. So, is it just time for it to be failing? Sometimes it fails when inserting cable, sometimes just walking into garage (coincidence?) or just charging stops. At Supercharger it worked fine.
