Dremel MultiPro 395 Troubleshooting

Dremel Multipro won't turn on

You can't get your Dremel Multipro tool to turn on, no matter what you do.

Make sure the Dremel is plugged in

Before you try anything else make sure that the device is properly plugged into a working electrical socket.

Brushes get clogged up

Sometimes particles of dust or whatever you are working gets caught in the brushes of the device. You will need to disassemble the device and clean the brushes. See our guide on how to do so. Dremel MultiPro 395 Carbon Brushes Replacement

Stator wires not making contact with the connector

Sometimes the stator wires will cease making contact with the connector. Fixing this will require disassembling the Dremel in order to get to the stator wires in order to reconnect them to the connector.

Device is turned on but is not running/working

If you plug in your MultiPro it will turn on but, it will not start working.

Dirty motor

Before tearing your device completely apart your dremel motor could just need to be cleaned with some rubbing alcohol.

Bad Switch

If your Multipro still is not running after you have cleaned it with rubbing alcohol the problem could be that your switch is bad. If this is the case you will need to go into your device and remove the old switch and replace it. See our guide to do so. Dremel MultiPro 395 On/Off Switch Replacement

Bad Motor

If the switch is fine and the cleaning didn't work then there is a problem within the motor. If this is the case please see our guide on how to remove the motor and check it for problems. Dremel MultiPro 395 Armature Replacement

MultiPro runs at inconsistent speeds

The MultiPro either runs very slowly or has no inbetweens between on and off.

The carbon brushes are worn out

Located on the either side of device are blue caps. underneath these caps are carbon brushes that contact the commutator. After many hours of usage of the tool these brushes tend to get worn out. Fixing this will require taking these caps off and replacing the brushes. See our guide to do so. Dremel MultiPro 395 Carbon Brushes Replacement

There is a faulty TRIAC chip

There is a small chip in the variable speed motor controller PCB board called the TRIAC that can become faulty overtime. You will need to open up the Dremel tool and replace the TRIAC chip.

There is a burning smell coming from the MultiPro

A foul burning odor comes off the device while it is running.

Dust build up

Sometimes, if you are using the MultiPro on something that creates a lot dust, like dry wall, then some of the dust can get trapped in the tool itself and cause a burning smell. The easiest solution is to get a can of compressed air and spray it into the openings on the side of the device in order to force the dust out.

Carbon brushes need replacing

Located on the either side of device are blue caps. underneath these caps are carbon brushes that contact the commutator. After many hours of usage of the tool these brushes tend to get worn out. Once this happens, sometimes it produces the burning smell you are smelling. Fixing this will require taking these caps off and replacing the brushes. See our guide to do so.

Burnt out motor

If the MultiPro is being used to do something that it doesn’t have the motor power to do, it can burn out the motor and produce a burning smell usually accompanied by smoke. Repairing the device, if this is the problem, requires replacement of the motor shaft, see our guide on how to do so. Dremel MultiPro 395 Armature Replacement

The button does not work

No matter what you try the button power button doesn’t seem to work properly.

The lock pin and spring wear out

The lock pin located toward the front of your Dremel MultiPro is the button you push when you need to change the bits on your router. Over time, the lock pin and spring will eventually wear out and the pin does not fit into or go into the hole in the rotating shaft. When this happens, you will need to replace it. This requires you to disassemble and reassemble the device.
