I’m hoping someone can help because I’m currently at my wit’s end with this thing… I have the Nest thermostat that I installed about a month or so ago. Immediately I got the N260 code regarding power, so I ordered the power connector and installed it. Everything seemed to be working fine for a couple weeks until we had a new AC unit installed. Suddenly the N260 code was back so I did a power test and it seemed to fix the issue…. For a couple days. Then the code was back and now when I do a power test the power connector is showing “not detected”. I’ve checked everything a million times. Reconnected all the cables… reset the unit.. nothing helps. Sometimes the code will say wiring info is wrong. I’m not sure what has changed! Here’s a picture of how I have it wired. Any suggestions are much appreciated. I’m starting to think maybe I have a faulty power connector??!
