I have an indoor sensor that has worked for 3 years. The other day the LED AQI light stopped working. The sensor is still working and the Purple Air map is updated. Any ideas why the led stopped working?

My LED stopped working too, and I got my PA-1 only four months ago. What gives?

My sensor often goes dark when I move it while cleaning the shelf under. Just knocking on it helps bring it back to life. Looks like a loose contact. I have A PA-I-LED 7.04 version.
