There are two different ways the heart rate monitor will fail. the first way is for the heartbeat monitor to stop giving a reading and the second way is for the lights on the back of the smartwatch to stop working.
If the heartbeat monitor is not tracking your heartbeat, go to the settings option and go to heart rate tracking. change the fit to automatic, make sure the band is tight around your wrist. if it is not tight enough, the heart rate monitor cannot read your heart rate. try moving the band around your hand with variations higher or lower on the arm. If it still doesn’t work, try turning on the settings. this will enable the green light on the back of the tracker even when you are not using it. Note: If it still doesn’t work, please reset your tracker using our previous section how do I reset my tracker?
If the lights don’t work, check your profile settings to make sure your heart rate setting is set to auto or on.
If none of the above fixes the problem, then you have a faulty heart rate monitor. contact fitbit customer service to request a replacement.
