My Dremel stopped working and it smell like burnt wires. What is the best way to fix this? Thanks Mike.
Mike for model number 400XPR asked on 2020-01-08
Hi Mike, Thank you for your question. If there is a burning smell coming from your rotary tool, the carbon brushes may be worn. You will need to inspect the brushes and if they are worn, you will need to replace them. check the motor as well. If it has burnt out, this could be the cause of the smell. If the motor has burnt out, you will need to replace it. If there is a burning smell coming from the rotary tool, there may be dust trapped inside it. If there is, spray compressed air into the openings to remove it. We hope this helps. Thank you and have a great day!
