Risk level

Low

Usually safe to check without specialist tools.

Urgency

Low

Quick answer

The heart rate glance on your Garmin watch says 'Disabled', shows a greyed-out heart with a slash or displays dashes instead of a number. Garmin asks you to check the sensor setting, Battery Saver, the fit on your wrist and a restart.

Safety first

Stop and check this first

  • A Garmin watch heart rate is not a diagnosis: Garmin states its wearables are not medical devices. If you worry about your health, speak to a doctor.
  • According to the Forerunner 965 manual, a restart may erase data or settings; if you still can, sync first and do not restart blindly.

Safe checks you can perform

  • Look at what the heart rate glance displays
  • Review the Wrist Heart Rate setting on the watch
  • Rule out Battery Saver
  • Adjust the fit, clean the sensor and restart if lights stay off

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Restart and update the software before blaming the sensor
  • Do not attempt this professional task: Re-enable sensor and glance following the model's manual

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Restart and update the software before blaming the sensor

    What they doIf the setting is right and no heart rate shows, the watch is restarted and the latest software is installed with Garmin Express.

    They must show youthe rear sensor lights on after the restart and the update finishing in Garmin Express.

    In writingsteps taken, their result and that no sensor fault is claimed from this display alone.

  2. Re-enable sensor and glance following the model's manual

    What they doThe technician checks the glance, the Wrist Heart Rate setting and Battery Saver in that order and leaves the sensor on, with the watch worn, until a number appears.

    They must show youthe glance displaying a real heart rate value after the setting is corrected.

    In writingwatch model, state of each setting before and after and that the device was not opened.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Look at what the heart rate glance displays

    No special tools

    Who:
    you, wearing the watch.
    How:
    scroll to the heart rate glance; if it says Disabled, select it to see whether it offers to enable the sensor, and on an older watch look for a greyed-out heart with a slash through it.
    Result that matters:
    learn whether the sensor is off, the glance is missing or only dashes appear.
    If the glance offers to enable the sensor and a number appears afterwards:
    already solved.
    If the glance is not in the list:
    enable it using your model's manual and look again.
    Evidence to keep:
    a photo of the glance showing the word Disabled, the grey heart or the dashes.

  2. Review the Wrist Heart Rate setting on the watch

    No special tools

    Who:
    you, in the watch menu.
    How:
    on the Forerunner 965 hold the menu button and open Health & Wellness > Wrist Heart Rate; check that Status is not off (the factory value is Auto) and remember that switching it off also switches off the wrist pulse oximeter.
    Result that matters:
    confirm that the wrist sensor is enabled in the watch.
    If Status was off and after returning to Auto the heart rate appears:
    the switched-off setting explained it.
    If Status was already Auto and still no data appear:
    look at Battery Saver.
    Evidence to keep:
    a screenshot or photo of the Status setting as it stands.

  3. Rule out Battery Saver

    No special tools

    Who:
    you, holding the watch.
    How:
    open Power Manager or Battery Manager in the settings and see whether Battery Saver is active; Garmin says it turns itself off once the watch has charged to at least 80%, or you can switch it off by hand.
    Result that matters:
    see whether the saver mode was keeping the sensor off.
    If after switching it off the sensor measures again:
    Battery Saver was the cause.
    If the saver was already off:
    move to the fit on the wrist and the cleaning.
    Evidence to keep:
    a photo of the Battery Saver state and the battery percentage.

  4. Adjust the fit, clean the sensor and restart if lights stay off

    No special tools

    Who:
    you, with clean water and a soft cloth.
    How:
    wear the watch above the wrist bone, snug but comfortable; rinse the back glass with clean water, dry it well and, if the rear lights stay off while worn, restart the watch as your model's manual describes.
    Result that matters:
    remove a loose fit, lotion residue and a sensor lock-up as reasons.
    If the rear lights come on and a heart rate appears:
    it was fit, dirt or a lock-up.
    If the lights stay off after the restart:
    do not open the watch and note the result for the technician.
    Evidence to keep:
    a photo of the back of the watch with the lights on or off.

What it means

Garmin's support page on a watch that no longer displays heart rate, plus the Forerunner 965 manual, explain that newer watches show Disabled in the glance when the sensor is off, and older ones a greyed-out heart with a slash. Other models may differ. Such a display does not prove the sensor is faulty, and a watch reading is never a medical diagnosis.

Symptoms and causes

Probable causes · in order

  • Heart rate sensor switched off in the settingsCommon

    Garmin states that on newer watches the glance reads Disabled and selecting it offers to enable the sensor; on older watches you see a greyed-out heart with a slash through it.

  • Battery Saver turned onPossible

    Battery Saver on compatible watches turns off features such as the optical heart rate sensor and wrist heart rate recording to stretch use when the charge is low.

  • Heart rate glance missing from the glance listPossible

    If the glance is not among those on the watch it has to be enabled first; each model's manual explains how to manage glances before you expect any number to appear.

  • Loose fit or dirty sensor with dashes on screenPossible

    With the sensor on and its lights flashing but dashes in the glance, Garmin points to a fit problem and mentions that residue from sunscreen or lotion can block the sensor.

  • Rear sensor lights off while the watch is wornLess common

    If the lights on the back do not come on while you wear the watch, Garmin says restarting it will often reset the sensor and restore its normal function.
