That being said, I have no idea what that specific error code means. Doesn't it peovide any more info? Maybe a Google rep can swing by and enlighten us.

Thanks for the tips. I am in Canada, the Nest was a gift so not sure where is was purchased, Nest was working just fine up until a few months ago. I have been through the guides but not luck.
