I received the Nano as a Christmas gift. I cooked a pork tenderloin successfully for New Year’s day. I’m trying to get my second cook in and ran into problems. I’m cooking a 3# sirloin tip. I have the device set to 140°F and started at 16 hours. About 5 hours into the cook, I started hearing noises that ranged from a low pitch hum to a high pitched whine to a rattling noise. I could find nothing online that described the sounds, but I did learn that sometimes the impeller gets out of alignment; so I unplugged the device, removed the cover at the bottom and spun the impeller.
When I tried to restart, I had trouble getting the Nano to pair with the app on my iPhone. I was successful ultimately, but I don’t know what I did to get it to pair. I think I was having difficulty getting the Nano to turn on. Once I heard it hum, my phone showed the Nano as connected; and I can see the temp and timer values in the app.
The Nano did not come with an instruction manual. I haven’t found one online. Can someone point me to one? I feel certain that I need to know more about the settings and how to use them.
