I have a Gen 3 that is stuck with the first quandrant blinking white 10 times then once red. Power cycled many times. Did factory reset by holding stop until blue light comes on but still stuck.
Called tech support and they are sending a replacement!!
I received a replacement controller on Friday and install went flawless. Everything has been restored to normal. Thank you Dylan for your excellent support!!! My controller was only a week from having the two year warranty expire. Dylan did not challenge this at all. I am very pleased and Rachio even supplied the label for free shipping return. Rest assured that if you have a problem, Rachio will stand behind their product!!!
