Indoor Sensor LED stopped working

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?

Hi @Shastadog, in this case, we are happy to look at options for sending you a replacement LED that you can install yourself. The following video will teach you how to complete that process: PurpleAir - LED - Google Drive. If interested, send an email to with your device ID and mention this post. Also, please include an address to ship the replacement to.
