Fitbit Heart Rate Not Working (8 Easy Ways to Fix the Problem!)

On a Fitbit Watch, you will find various sensors. Each sensor is meant to keep track of a given activity. Examples of Fitbit sensors include SpO2, accelerometer, ECG, heart rate monitor, and more. Unfortunately, the sensors (especially the heart rate sensor) may fail. In this post, I am going to talk about the heart rate monitor outlining reasons why it is not working, and provide fixes that will make it work again. So, why is the Fitbit heart rate not working?

To summarize, Fitbit is not tracking your heart rate either because of system errors or glitches, it is wrongly placed and thus not in proper contact with the skin on your wrist, the heart rate monitor is deactivated, or the firmware running on your Fitbit needs to be updated.

To get your Fitbit smartwatch or activity tracker to track your heart rate you’ll need to fix the causes mentioned above. Fixing these causes is easy and if you don’t mind I’ll guide you through.

Here is how to get the heart rate monitor on Fitbit Versa, Sense, Charge, Luxe, or Inspire to start working again.

8 Ways to Get the Heart Rate on Your Fitbit Working Again

1. Try to Restart your Fitbit

If your Fitbit Charge, Sense, Versa, Inspire, or Luxe isn’t tracking your heart rate, the first thing to try is restarting it. Restarting the tracker can fix system errors or glitches. Fortunately, restarting a Fitbit watch is an easy process. See the steps below to learn how.

To restart your Fitbit:

  1. Wipe down from the watch face to open the quick settings panel.
  2. Swipe through through the quick settings panel to find the Settings icon and tap on it.
  3. Swipe down until you find the Restart Device option and tap on it.
  4. Tap Restart to confirm you want to restart your Fitbit.

After the restart, the heart rate monitor on your Fitbit will start working again. Don’t worry, you won’t lose any data when you restart your Fitbit device.

2. Turn the Heart Rate Monitor Back On

If the heart rate monitor on your Fitbit Charge, Sense, Luxe, Versa, or Inspire is not working, it might be because the heart rate sensor is off. This can happen if you accidentally turn off the heart rate monitor while adjusting your settings.

The good news is that the solution is easy: just go to your watch’s settings and turn the heart rate monitor back on.

To check whether the heart rate on Fitbit is on or off do the following:

  1. Go to Quick Settings on your Fitbit Watch.
  2. Swipe through Quick Settings to find the Settings option and tap on it.
  3. Swipe down on settings to find the Heart Rate option and tap on it.
  4. Here you can see whether the heart rate monitor on your Fitbit is on or off.

If you found the heart rate monitor off in the settings then it is the cause of the problem. Tap on the heart rate option to turn on and your Fitbit heart rate should start working again.

3. Try to Update Your Fitbit

The heart rate monitor on your Fitbit is not working properly or not working entirely because the firmware is not updated.

Fitbit updates its firmware frequently to fix bugs and improve the performance of its watches.

You are likely using the old firmware and as a result, having problems with the heart rate monitor on your Fitbit smartwatch or activity tracker.

Like the rest of the fixes offered, this one is also easy. You just need to update your Fitbit and after that, the heart rate feature on it will start working.

So how do you update a Fitbit smartwatch or fitness tracker? Well, the process of updating a Fitbit smartwatch or tracker is easy, see the steps below:

Step 1: Open the Fitbit app on your phone.

Step 2: Tap on the Settings icon to go to your Account page.

Step 3: On your account page select your Fitbit Device.

Step 4: Tap on the Update Tracker option.

Step 5: Tap Start Update. The Fitbit app will connect to your Fitbit watch, search for Wi-Fi, and then download and install the latest firmware on your Fitbit.

Most importantly, make sure your Fitbit Watch and phone are close or in range. Additionally, ensure your devices especially your Fitbit Watch have enough charge because you don’t know how long the update will take.

So, if your devices are low on charge consider updating them while connected to power, that way neither of them will turn off in the middle of the updating process.

4. Clean the Sensors on Fitbit

Fitbit tracks heart rate data using the sensors at its back. These sensors need to be clean to flashlights and read your heart rate accurately.

If you stay for too long without cleaning the sensors they may collect dirt which hinders the flashing lights and as a result heart rate stops working or reads inaccurately.

If the sensors are dirty consider cleaning them and once they are clean your Fitbit heart rate should work properly and accurately.  

5. Wear Your Fitbit Properly

To ensure that the heart rate feature on Fitbit works properly, it is important to make sure that the sensors are in contact with the skin. If the Fitbit is moving around on the wrist, it may not be able to measure heart rate. It’s recommended to check the bands and tighten them if they are loose.

6. Wear Fitbit on the Inside of Your Wrist

If you have a tattoo on your wrist, it may impact the accuracy of heart rate readings from your Fitbit. To address this issue, it is recommended to wear the Fitbit on the inside of your wrist.

7. Reset Your Fitbit

If the solutions provided in the guide do not get the heart rate to work, it may be necessary to reset your Fitbit Watch. However, it is important to be aware that resetting the device will erase all health and fitness data, as well as settings stored on it. To avoid losing important data, it is recommended that you back up all your Fitbit data before proceeding with the reset.

8. Contact Fitbit Customer Support

If all the solutions offered (including reset) did not get your Fitbit heart rate to start working it means your device has a serious problem. Get in touch with Fitbit and they may help.
