The Nest Community is now Google Home & Nest!
We have moved to a new home. Please visit the Google Home & Nest Community to connect with other users, ask questions, and explore the new space.
Our A/C unit is over 20 years old, we just got the E103 error but
nothing has changed. Before I call warranty on the a/c unit itself, is
it possible they will just want to replace the Nest and not the whole
unit?
