Fitbit Blaze Heart Rate not working

[Darcyos03]

I have had my Fitbit for just over a month and the heart rate is not working. If I turned it on auto it would flash once every three seconds and on my Fitbit it would just have two dashes on the clock face and same in the today area and when I change the heart rate settings to on it shows 70 on the clock face but in the today area it had dashes. No matter what I would do it would stay 70. I have reseted it a few times but nothing has changed. What should I do?

Mine is doing the same thing. After replacing the first one because after a month it would not longer charge. This new one I have had less than 24 hours and same issue. Along with it not tracking my steps like the last one.

Welcome to the Forums @TheRealNicole and @Darcyos03! As with all heart-rate tracking technology, whether a chest strap or a wrist-based sensor, accuracy is affected by personal physiology, location of wear, and type of movement. For all-day wear when you’re not exercising, your tracker should usually rest a finger’s width below your wrist bone and lay flat, just as you would wear a watch. Fitbit’s PurePulse heart rate tracking system is designed to be most accurate when the tracker is worn on the top of your wrist.

For improved heart rate accuracy keep these tips in mind: 

1. Experiment with wearing the tracker higher on your wrist. 

2. Do not wear your tracker too tight; a tight band restricts blood flow, potentially affecting the heart rate signal.

If you already tried this and to restarted your Blaze by following the steps @SunsetRunner shared on this post and you are still having issues with your heart rate readings please reach out to our support team for assistance. They can take a look at your tracker's back-end information and provide you personalized troubleshoot. 

Let me know how it goes! 🙂
