My unit, which was purchased in October 2015, worked for several months - sporadically at times - but recently it went completely offline. I've not had any internet issues so I tried to reset the unit manually as instructed by Chamberlain troubleshooting guides. No luck. I cannot seem to get to the "blinking blue light" step. I hold down the gear button, but nothing happens, even after a minute. I have no idea what to do next and feel like the unit has bit the dust. Just to be clear: this unit hasn't been moved from the garage once I installed and commissioned it. It worked well at first, then I began getting false messages (door has been open for 20min; no, it wasn't, etc) and not it isn't connected and won't reset.
