I do not have a c wire either and the nest learning 3rd gen thermostat works for me

The only answer is to get a new one. If it is under warranty they will replace it otherwise it is on your dime.

turns out mine is still under warranty so will be getting a replacement. But it took 4 hours on the phone because the links they sent did not work. If it happens again I'll live without the internet since my choices are limited since I have no C wire

Well it took 4 hours on the phone and three links to finally get to order a replacement thermostat. There has gotta be a better way to do this

Seems this is a common problem. I'm one of the lucky ones since my thermostat is still under warranty and google will be sending a replacement
