Garmin Fenix 3 HR: How to repair heart rate sensor?

Wed, 07 Oct 2020 07:25:14 -0700

Hi guys!

My heart rate sensor is all cracked and about to fall apart. Is there any advise on repairing this part of the watch?

I've read that the glass part of it is a kind of resin based stuff. Won't be easy to fix I guess.

Many thanks in advance!

Garmin Fenix 3 HR: I want to replace my bezel ring.

I have a Garmin Fenix 3, I want to replace the bezel, and no body has a guide for it. So my question is when I take the bezelnoff and the LCD screen comes with it. Will the LCD screen just pop off or is it glued in?

Garmin Fenix 3 HR: Replaced battery, watch not coming on.

Wed, 21 Sep 2022 08:58:25 -0700

I replaced the battery. Went easy with the online instructions. I did not receive any adhesive with the battery. I substituted. The watch display is blank. Put in charger overnight, screen shows 100% with USB power symbol, not battery symbol. Switched back to my original battery and it works normally. Only problem is original battery is not holding a charge like it used too. That is why I chose to replace it. Is there a step I am missing to get the watch to recognize the replacement battery?

thank you.

Garmin Fenix 3 HR: My Fenix 3HR keeps freezing during activities - HELP

Wed, 28 Aug 2019 13:08:37 -0700

I’ve had my Garmin Fenix 3HR for a few years now and use it for trail running. It has always froze up from time to time. It can be a run of 2 hours or 20 hours but it happens every so often. During the activity it freezes on one of the screens as it scrolls through automatically. It will do this if I have it locked or unlocked. When it freezes the watch does not continue to record. If I hold the light button for a bit it will finally power off and then will power back on but takes a bit (it hangs out on the Garmin logo screen). When it does come back on I can resume the activity but it loses everything between the freeze and when I resume. If it take 20-30 minutes it may miss 2 or more miles. Once uploaded it draws a straight line showing it skipped that portion and obviously my mileage, pace, elevation, etc are all inaccurate due to the issue. I have done hard and soft resets. I plug into the computer and ensure I’m up to date and every so often I delete my history from the watch itself. The watch is in fine condition but I am just fed up with the issue. Before I give it and get a new watch I was hoping someone could help me trouble shoot the issue.

Thanks!
