LOL! It is so hard to find the phone number to call Nest for a warranty
service. I posted it the number here thinking it will help others, but
all I see is ##########. OMG! So it is for sure their intent to keep the
number hard to find no matter what...
############Called this number and in about 30min the helpful technician
verified my device Nest 3Gen Learning Thermostat SN, my Gmail account
and set me up for a return. Waiting for emails with the instructions for
the return.I will let you know how...
