Volume Level:

It is also a trivial cause for iPhone alarm not working that people unknowingly turn up the Media Volume rather than Ringer Volume. Actually, this misconception arises due to two different controls to adjust volume i.e. Media Volume & Ringer Volume. Ringer Volume adjusts the sound for all the notifications, reminders, system alerts, alarms and ringer, while the Media Volume is for all the music, videos, games and other in-app sounds. So make sure that you turn the Ringer volume up by checking if the volume meter label is set as "Ringer" or "Volume" because "Ringer" stands for "Ringer Volume" while "Volume" stands for "Media Volume". This is a simple but necessary check if you met the problem that iPhone alarm not working.
