how to fix lb on xbox one controller

The left bumper on the Xbox one controller has started to misbehave? Don’t worry because this section carries a lot for you. Of course we will take you through an ultimate guide, as long as you assemble specific tools and materials.

Step 1: Remove the battery cover

Removing the battery bay covering is always the first action to fix LB on an Xbox one controller. This action is essential since it gives you a chance to access the AA batteries.

Now that you can see the batteries, remove them too from the pack; they should be two. There is no big deal in this step, but ensure the batteries are removed.

Step 2: Detach side handles

Removing the side handle cover is one of the major tasks involved under this step. Start by firmly gripping the controller to uncover the side handle.

I don’t know the exact tool to help you, but a spudger or a flathead screwdriver can do wonders. They are useful for wedging around the side panels. Check this flathead screwdriver on amazon.

Try moving the flathead screwdriver fourth and back so that you can easily pry the side panel.

Moving the flathead screwdriver fourth and back around the side plates should be done along the front seam to comfortably remove the side handle panel.

Another critical action that you should not forget under this step is opening the seven clips. Once they’re opened, they will release the side handles to easily remove them.

You can now go on and push forward the plate.

Step 3: Remove the puncture or sticker

There are several screws that you are supposed to remove, starting from the battery pack. They are usually covered with either a puncture or a sticker; so if you aren’t careful, you may not spot them.  

Look where there is a sticker and remove it carefully to access the screw. Alternatively, you may just make a hole in the middle label using a screwdriver. There you’ll see a hidden screw.

Here, a TR8 screwdriver will be of much help to you. You should use it to unscrew five 10mm screws from the controller’s back.

Step 4: Remove backplate

After ensuring that there’s nothing holding the components together, it is now time to remove both plates.

You can start with any, but for our case, we shall start by removing the backplate. Place it in a secured place so that you can reach out to it easily when need arises.

Step 5: Detach a faceplate

Go on and detach the faceplate too since there are no side handles or TR9 Torx screws that hold it. Why are you staring at the plate, my friend?

Remove it from the controller and place it on a secured place; where you can easily see or touch it to avoid unnecessary damages.

Step 6: Clean the LB

Clean the LB

Sometimes these controllers accumulate dust or dirt that if not cleaned, the device may become unresponsive. For this reason, you are required to give your LB on Xbox one controller a thorough cleanliness.

Under this step, there are reputable cleaning substances like isopropyl alcohol and microfiber cloth.

Start by dampening the cloth in the alcohol before giving the bumper a few wipes. Just wipe down the bumper; but not gentle. You may break the bumper or extend its defects.

The next action should be drying the bumper before you even think of using it. You may use the same piece of cloth, but the dry side to completely wipe down the wetness.

Cleaning the LB shouldn’t give you a lot of stress since it is very simple; once you have the necessary cleaning agents and materials. Advance to the next step.

Step 7: Remove the plastic covering

There is a cover piece around the Xbox one button that has to be taken off the pegs. The plastic cover is always located in the middle, connecting the bumpers.

You are therefore required to detach this plastic cover by lifting it up over the two pegs.  

Hold your controller firmly and then lift up the cover piece from the pins/pegs. Press the home button before you push the cover to the top of your controller; this will help you unclip the cover piece.

However, a lot of care is required under this step because you don’t want to affect the functioning of the home button or the plastic piece.

NOTE: You should take care of the sync button which is loosely mounted beneath the plastic covering. DO NOT forget to place it back before you re-install the bumper assembly or plastic over. 

Move on to the next step which involves pulling out the problematic bumper.

Step 8: Remove the old bumper assembly

 Remove the old bumper assembly

After disassembling almost everything, the remaining task is now to fit in a new bumper assembly. This process is somehow straightforward if you have strictly followed the above steps.

Here, you should start by removing the problematic bumper by unpinning it from the pegs. Go on and fix the LB Triggers for Xbox One Controller by aligning it on the controller. However, you should remember to hold down the triggers.

The four pins of the LB should be aligned on both sides before mounting the new home button cover. Make sure the new bumper is gently clicked into place.

Step 9: Finish

If you are lucky the problematic LB on Xbox one controller is now working. A good number of people may neglect testing the device, only to realize that the entire process was in vain.

Testing is therefore recommended to determine whether the entire process is successful or not. To achieve this, connect the controller to the Xbox one and then take note of its workability.
