There's a very strange test/alarm sound that occurs every 34 minutes. I checked the smoke alarms and replaced the batteries so it's not coming from those.

It almost seems to be coming from the kitchen, maybe the fridge? But I cannot quite pinpoint it.

Please see the link below for a sample of the alarm sound.


Thank you! Colin

    I know my refrigerator makes noises when it thinks the water filter needs to be changed. – jwh20 May 29 '19 at 18:15
  • Thanks for the reply. I checked our fridge and it's a sub-zero 611, which according to their website does not have a water filter. I was hoping this was the issue. Guess it's back to looking for the noise again. – Colin May 29 '19 at 18:36
  • It sure sounds like my smoke alarm when I need to replace the batteries. How do you know it’s not the smoke alarm? – Lee Sam May 29 '19 at 18:49
  • I replaced all the batteries inside my unit. It could be from outside hallway since I do live in an apartment complex. I will check. – Colin May 29 '19 at 18:58
  • removing the batteries from the smoke alarms makes more sense if you are trying to determine if a smoke alarm is making the noise – jsotola May 29 '19 at 19:14
