Blank screen/green flashing light loop on Nest 3 (previous thread prematurely closed)

[johnstehlin]

Hi, I'm having the same problem reported on this thread: https://support.google.com/googlenest/thread/19954351/my-nest-thermostat-is-blinking-green-with-a-bl.... My Nest 3 screen is dead. When I charge with a micro USB I get the "G" logo and then a message to plug it into the wall. When I plug it into the wall it goes into a loop of one flashing red light, then a flashing green light, then quickly to orange, then solid green briefly before restarting the loop. During the loop there is a high-pitched buzz.

I tried everything in this thread as recommended by @GarrettDS in this thread, but then he closed it mistakenly since it was not me who resolved the issue, but another user: https://www.googlenestcommunity.com/t5/Nest-Thermostats/Blank-screen-and-green-flashing-light-loop-w....

Following the first linked thread, I've plugged the Nest into my computer and have located the .plist file. At this stage, previous troubleshooters have messaged users privately for further instructions. How should I proceed? I do not want boilerplate instructions that I have already tried.

I am having the exact same issue. When I installed, it worked. Tested both the air and heat, those worked. At some point the nest lost WiFi connection even though all my other devices didn’t. I tried all the trouble shooting steps all the way down to reinstalling my old thermostat and it works just fine. But the nest keeps looping on the G screen (I’ve reset it 25+ times). Sometimes it flashes 3-4 times before going back to a solid g with green blinking light. I charged the nest thermostat over night and still nothing. Plugged it into my computer as recommended in other threads but it’s not clear what to do next.

Every thread I’ve read on this goes to private messaging at this point and won’t share what the fix is. This is so frustrating to users.

Hi there BandL, 
We're sorry to hear you're experiencing WiFi connectivity issues as well despite troubleshooting! Unfortunately, some Nest users were affected by a persistent W5 error/issues connecting to their Internet, which our escalated tech support specialists can help out with. I've created a case for your issue as well. Here's the reference number: 2-4982000032235.

Best,

I am also having this issue with one of my units. Is the only fix to replace it? I’ve been troubleshooting and cannot get it to work.
