Black and Decker LDX 120C Troubleshooting
Unit won't start
The battery is fully charged and when I try to use the drill it is not functioning at all.
Battery is dead
The battery might not be functioning anymore, if the battery doesn’t provide enough charge the drill will not be able to function. So you will want to replace the battery.
If the wiring connection between the battery and the chuck is lose or not connected properly then the drill won’t function. So you will want to check on the wiring connection to make sure nothing is lose.
If the drill has a lot of dirt or stuff that accumulated in the chuck it might be jamming the drill and clogging the rotation. Make sure you clean the residue inside the drill.
If the motor is not functioning it might be because of multiple reasons. Some of the components might be broken, and you will want to replace these components. It might be because of loose connection; fix the wiring. Battery might be weak so the motor doesn’t function; change the battery. Follow our Motor Replacement Guide
Battery won't charge
No matter what I do the battery is not charging
Defective charger cable
The charger might not be charging properly, so check on the charger or just try a different charger.
Battery no longer effective
If the battery has reached its life span it will not be powerful enough to supply the charge the drill needs. It will be best to change and get a new battery.
Air temperature too hot or too cold
If the drill overheats because of over use then it is best to let it cool down and disconnect the battery and then use it again. If it’s too cold then change the environment where you are using the drill.
Charger isn’t plugged in
The charger might not be plugged in completely so not enough electricity is flowing to charge the battery, so make sure the charger is plugged in correctly.
Unit shuts off abruptly
While using the drill it just completely shuts off and doesn’t work anymore.
Battery pack is too hot
After long use the battery might overheat which would shut of the power provided the drill. So let the drill cool off and then use it again.
The battery is not charged
After long use the battery might run out of power because it wasn’t charged well enough. So make sure the battery is fully charged and functional.
The motor is blocked
The motor might get blocked or jammed because of some component that got broken or loose, or the grease might have dried out, so make sure you open the drill up and check for the motor components. You can use our Motor Replacement Guide.
