Carib Inn Posted December 5, 2018 Report Share Posted December 5, 2018 Hello - first post. I have a new XPH10 cordless hammer drill that suddenly will no longer run but the light does come. Switch tests OK. Battery fine. I am not getting any voltage to the brushes. There is a small rectangular piece about 1/8 thick attached to a heat sink which sits under the motor. 3 black wires go to it. There is continuity through all wires so none are burnt. I have a feeling that is what is wrong but can not find that part in any schematic. What is it? Any other ideas? Can't send it back. I live in the Caribbean and it will cost more than the drill is worth.Thank you Bruce Quote Link to comment Share on other sites More sharing options...
CATERPILLAR Posted December 7, 2018 Report Share Posted December 7, 2018 Can you send pictures ? And did this just happen all of a sudden or when you went to use it ? Quote Link to comment Share on other sites More sharing options...
SchenzhenSpecial Posted December 7, 2018 Report Share Posted December 7, 2018 Motor controller transistor. The one currently installed in the drill should have a product code which you can search to find a replacement. They're quite cheap to replace. If you have continuity at all three points it most likely is faulty. It doesn't have its own item code on the spares catalogue, however.
