I recently received the Acurite Air Quality Monitor. It was fine for a while, then I noticed the temperature and humidity went to lines. The white number for air quality is still fine and works. The temp and humidity appears to be intermittent sometimes where it will go to lines and then comes back on its own, then goes out again. I also know there is a fan to pull in the air and I heard a hum of the fan before, but now I don't. Except, for when I tilt the device with the screen facing the floor, then I hear it until it stops again when it is standing up again in proper position. Honestly, I could care less about the temp and humidity features, but it is annoying when not all features work correctly and lines are showing. So, not sure what the deal is, but seems like a loose connection of some sort with a connection inside the device.
