Heart Rate Monitor not functioning

My Garmin Vivoactive 3 has stopped recording my heart rate, and the green light is no longer on. What could be the problem, and how do fix the issue?  Everything else is working fine. 

  • Either the HR is disbaled in the settings, or the watch is perhaps in the power-saving mode disabling it automatically (though I am not sure whether Vivoactive 3 has such a mode), or the device is defectuous. For the first two cases - check out the settings of the watch (and the documentation if necessary), for the last case contact the reseller or Garmin for the replacement.
