Question about Dewalt Drills

My dewalt 18 volt Dc988 XRP will not engage when you squeeze the trigger all the time. It goes in streaks or is intermittent. Also the variable speed is not working. it only goes one speed.

Your switch is having a problem it can be caused by excessive load on the motor.
The motor must be sounds not shrill and must have power , the most people think on the batteries but in more case by switch problems its the motor there is a field effect transistor inside the switch behind the cooling brass plate thats shorted and that is for the variable rpm .
Replace switch and if the motor sounds good then the problem should solved. if also the motor is bad go for a new replacement body ask your dealer.

Switch sometimes does not work


The switch on these drills is notorious for doing exactly what you describe. One thing to check is the battery terminals on the bottom of the switch, they get bent or broken off easily. It could also be internal to the switch but the only fix is to replace it. You need Dewalt part number 152274-22 to repair the drill. It's a fairly easy repair but shop the internet, they cost from $55 to $75 plus shipping.

Dewalt cordless drill dc988- drill motor works intermitantly when trigger is pulled. Works a little better as it warms up. Im thinking vsr switch, brushes, or motor/armature. please help...


Test the brushes by catching it in a stalled condition when you have it triggered, then rotate it slightly. If it takes off suspect the brushes or a dead segment on the comutator.

If it doesn't respond to this, then consider the VSR trigger... open it and test by bypassing it when in stalled condition...

If you noticed this sound the first time you tried the drill, it is noise of the armature brake.  This noise is normal and not a problem at all.  Michael Mittelsdorf
