Sorry to hear about your Nest Learning Thermostat but thanks for reaching out.
Could you tell us more what's going on with it? Why do you say that it is not working? Are you getting a specific code or message on it's display or on your Nest app?
Tell me more so I could dig deeper into it.
Just checking in to make sure that you've seen our response. Please let us know if you have other questions or concerns as we will be locking this in 24 hours if we won't hear back from you again. Feel free to start a new thread and we'll be happy to help.
Thanks for the help here, Melba.
