Laser levels can be considered complicated devices, especially if you are new to the experience of using the device or a new model.

When the unit stops working of malfunctions in the middle of your work, it can really cause undue stress and unnecessary delays.

There are tricks that you can do to solve the issues before sending it for professional repair.

Laser level stops working

First, check the power source. If you’re using standard alkaline batteries, use a new set.

Try standard batteries if you are using rechargeable batteries, but only if the device comes with this feature. You may also plug it into the main adapter to check if it’s working.

Try connecting the laser device to a DC power source or external power supply. Always make use of the combined AC/DC converter and charger provided with the equipment. Using other materials might lead to permanent damage.

Then, check your manual or instruction book for troubleshooting tips to handle simple issues. If the problem persists, contact the laser level manufacturer. Contact details are usually found inside the carry case.

The manufacturer usually has a better understanding of the device than the supply outlet where you purchased it from and you may be given instructions on how to solve the problem without necessarily sending the product back.

Leveling malfunction

If alignments or leveling is not properly set, it surely will affect your output.

Check the placement of your device. The laser level should never be placed on a surface with heavy vibrations or in areas where heavy machinery is being operated.

The unnecessary vibrations can significantly affect the leveling or alignments giving you unsteady unreliable lines.

Be sure to place your laser level on a firm surface on a tripod stand or via pole leveling. It can also be mounted on the wall.

Laser beam is not visible due to bright light

Sunlight or bright light may make the laser level beam invisible to the eyes. To address this, use a laser detector which can make the beam visible amidst the bright environment.

The combined use of laser level detector and the laser level can yield to more accurate leveling.

If the laser level device placement is above the head level, the detector needs to be adjusted to a high level for best results.

Laser is not rotating

First, check if the head still spins by hand. The head gears could be jammed or the compensator (vial) is already defective.

Be sure that the device is also completely leveled. Note for loose connections from a fall.

If the problem persists, bring the device to a repair center. A lot of laser level dealers diagnose the unit for free.

Remote control dysfunction

Understand that the remote control functions only with a direct, uninterrupted line of vision from the remote sensor to the sensor in your laser level. It doesn’t function when there is any blockage or interrupting object in between.

Also, use the remote control within the specified range and change the batteries regularly when required.

Mishandled and dropped laser level

When the laser level unit is dropped or mishandled, the unit may lose all of its settings or the unit may possibly be damaged. Perform a horizontal plane calibration test to check if the laser is still functioning properly.

Conduct a calibration test as well to check whether the device is working as it should.

If there are any defects or problems observed after these, consider seeking professional help.

The device is not responding or immediately shuts down

If the laser level device cannot perform rotary functions, check the unit thoroughly. Check the joint of the rotary for any corrosion. In cases of corrosion, apply some anti-corrosion ointment to clean it.

When the problem persists, it may be due to a motor issue which needs replacement. You need to send it to the service center for professional repair or replacement. Check if the unit is still within the warranty period.

There are minor problems that you can usually encounter with the use of your device which needs adjustments to make it functional again.

It’s important to equip yourself with basic troubleshooting tips and tricks along with proper maintenance of the device to keep it working, such as keeping it in a cool dry place, proper cleaning and regular calibration.

If the laser level still fails to function after trying simple troubleshooting techniques, call the manufacturer or service center for advice or bring the device in for further repair or replacement.

      Something went wrong with the vertical laser diode, I guess. I suggest that you bring it to the service center for repair or replacement.

    Laser seems to be “too high” in the black spinner window. It is not reflecting off of the mirror. The beam looks to be split in two out of the top window. The unit has worked perfectly for four years and now nothing. Cst/berger algr

      Hi Jerry, sorry to hear that. I have never met such a problem with my device. Have you contacted the manufacturer and told them your issue? Maybe they can help

    • Bruce M. Rivers says

      Hi Thomas, have you just bought the receiver or have you used it for a period of time? I can’t say exactly what is going on. But this seems a big issue that we can’t fix by ourselves at home. It’s time to look for support from the manufacturer. Bruce

    Hi I have a grade laser level(datum)

    I tried to use it today and the, laser rotated and produces a beam, but the detecot wouldn’t pick it up, so I bought a new one and that’s will not pick the beam up either. I have cleaned the lense and changed the batteries, still doesn’t work??

    Do you know what’s wrong and could you repair?

    Many thanks

      Hi Lloyd

      If you’re using a detector from another manufacturer of your laser level, please check if the detector is compatible with your laser level by reading the user manual of both the laser and detector. Not all detectors are universal, in fact, most detectors only work with a particular laser wavelength, so it is advisable to check the compatibility of the detector with the laser.
      In case you use a green beam laser level, you need a detector that can detect green line laser too.
      If it still doesn’t work, don’t hesitate to contact the manufacturer and ask them to suggest the right detector for your laser level.

      Hope this helps
