Last Updated: Feb 1, 2024 by

If you’re experiencing issues with your mouse scroll wheel jumping or scrolling in the wrong direction, you’re not alone. This is a common problem that can be caused by a variety of factors, including a faulty mouse scroll wheel encoder. In this article, we’ll discuss how to fix a mouse scroll wheel that is going up and down, so you can get back to using your mouse without any frustration.

Check for Physical Damage

The first step in fixing a mouse scroll wheel that is going up and down is to check for any physical damage. Inspect the scroll wheel for any debris or damage that may be causing it to malfunction. If you have a wireless mouse, make sure the batteries are not low or dead. If you find any physical damage, you may need to replace the mouse or take it to a professional for repairs.

Clean the Scroll Wheel

Over time, dust and debris can build up on the scroll wheel, causing it to malfunction. To fix this issue, you can try cleaning the scroll wheel with a cotton swab and rubbing alcohol. Gently rub the swab around the scroll wheel to remove any dirt or grime that may be causing the issue. Be sure to let the alcohol dry completely before using the mouse again.

Adjust Mouse Settings

If the physical components of your mouse seem to be in good condition, the issue may be with your mouse settings. To fix this, go to your computer’s control panel and open the mouse settings. Look for an option to adjust the scroll wheel sensitivity or direction. You may need to play around with these settings to find the right configuration for your mouse.

Update Mouse Drivers

Outdated or corrupted mouse drivers can also cause issues with the scroll wheel. To fix this, you can update your mouse drivers by going to the manufacturer’s website and downloading the latest drivers for your specific mouse model. If you have a Razer mouse, you can also use the Razer Synapse software to update your drivers.

Replace the Scroll Wheel Encoder

If none of the above solutions work, the issue may be with the scroll wheel encoder. This is a small component inside the mouse that helps translate the movement of the scroll wheel into actions on the screen. If this is the case, you may need to replace the encoder. You can purchase a new one from the manufacturer or take your mouse to a professional for repairs.


A mouse scroll wheel that is going up and down can be a frustrating issue, but with these tips, you should be able to fix the problem and get back to using your mouse without any issues. If you’re still experiencing problems, it may be time to invest in a new mouse. Have you encountered this issue before? Let us know in the comments.
