Blaze stopped reading heartbeat

[Clauswitz]

My 2 year old Blaze suddenly stopped reading my cardio. Reset it several times. No reading heart rate so incorrect calories, no sleep tracking. Etc. Any fixes?

Hello @Clauswitz, welcome back to the Community forums. 

I'm sorry to see that you've been having trouble with your Blaze that suddenly stopped reading your cardio information. Thank you for confirming that you already tried to restart the device. Could you please confirm if the green light on the back is not turning on at all, or if it is turning on but you're not getting any heart rate information? 

Before considering other options, if you're still experiencing the same behavior, please make sure to check the information provided here to improve the accuracy of the heart rate readings. 

Please keep me posted.

Yes the green lights flash intermittently. I have tried moving the watch up and down my wrist and tightening and loosening the wristband. I have worn a Fitbit device since 2015. I have had some issues in the past but not this.
Regards

Hi there.  Ive just started to experience the exact same problem. The green lights at the back of my blaze have stopped flashing. I have reset the device but unfortunately no luck. No and again I see a very weak flash of one of the lights. Please can you help?

Here is what Fitbit came back with. It restarted reading. Seems resolved.From the Fitbit app dashboard, tap the “Today” tab > your profile photo.
Tap your Blaze tile.
Tap “Heart Rate”  
Switch your tracker's heart rate setting to On and sync.
Wait at least 60 seconds before your checking heart rate again.Good luckSent from my Bell Samsung device over Canada's largest network.
