After only 15 months' use our new Nest learning thermostat stainless steel PRO Edition failed, confirmed by our electrician. The energy-saving co that installed it offers only a one yr warranty. I cannot seem to check the warranty status online because my wife, who has a Google.com account, never set up a HOME in her account. She simply managed the thermostat over Wi Fi. I called the Nest Warranty number 650.331.1127, waited an hour while multi-tasking, finally pushed a digit to leave a msg to get a call back but got a msg the mailbox is full and messages are not allowed. This seems very difficult. QUESTION: given these circumstances, how can I check to see if Google offers more than a one-year warranty on my unit? i have the serial number. thanks, Lee
