Cordless Drill: No Reverse
if there is no reverse on your cordless drill, check either the lever or the switch. Once you have determined the part that needs to be fixed you can now use our expert guide to repair it yourself. Check your owner's manual for specific advice regarding your model.
Levers
To replace the lever, first remove the end cap on the drill then remove the two screws holding the transmission to the motor on the side of the transmission, where all of the housing screws are facing upwards, securing the cover to the housing. Next, remove the screws securing the cover to the housing and pull the cover off. Pull the trigger switch up enough to remove the forward/reverse lever out. Install the new lever and make sure the tab on the switch aligns with the post on the switch. Make sure all wires are in their proper channels so they do not get caught when reassembling the cover back on the housing. Finally, put the end cap back on. ... Read more
Switches
The switch allows current to flow to the motor when you pull it back with your finger. If the drill will not rotate in reverse only and you have already replaced the forward/reverse lever, then the next step would be to replace the entire switch.
To replace the switch, start by removing the end cap on the drill. Take out the two screws holding the transmission to the motor on the side of the transmission where the housing screws are facing upwards, on the case, securing the case to the housing. Next, remove the screws securing the two halves of the case together and separate. Take out the other two screws on the transmission that secure it to the motor. Remove the screws securing the hold-down brackets on the motor and then the motor and transmission assembly. Remove each wire from the brush holder and do not mix up where they attach too. Remove the switch from the drill and install the new switch into the housing.
Connect the wires in the slots, inside the housing, and wire them to the correct brushes. Insert the brushes back into the drill housing. Reinstall the motor and transmission assembly back into the drill housing. Reinstall the hold-down bracket and secure them with screws. Reinstall the two screws securing the transmission to the drill case and then the second brush holder into the drill. Put the case back on the housing, followed by the other two screws, securing the transmission to the motor. ... Read more
