Hi. Sounds like you have worn out motor brushes. the brushes wear down to short and get stuck in the brush holders. Sometimes the caps that hold the carbon brushes in come loose, and the carbon brushes get stuck because the current arcs between the carbon brush and the brush guide. Get a serviceman to overhaul the motor, and it will work fine. Probably a good idea to replace the motor bearings at the same time. Good luck. Neil.

1. Shut the power off, and disconnect your Ryobi
router. It could be the start/stop switch. So, you
can begin checking the switch contacts using the
multi-tester. Set if at 1 x 10 Ohms. Put the probes
of the tester across the switch terminals. Pressing
the trigger on will move the tester indicator to zero
if your switch is okey. Otherwise, no moverment -
the trigger switch need replacement.
2. Should the trigger switch proved to be okey, Check
the carbon brush of the unit, short carbon brush??
you have to replace it.

Then power is not reaching the motor ie bad connection past relay or the motor is toast, worn so badly theirs no connection through brushes. Some times just dirty or carbon build up. Low voltage is usually the culprit, running accessories like these without the engine running or with a weak battery can result in excessive heat and arcing can occur causing carbon deposits making contact impossible. Sometime slamming the door will instigate contact and it will run for a bit but the damage is done and repairs from cleaning to replacing are in order.

It sounds like the armature has developed an open commutator bar. What did the brushes look like that you took out. But before I assume the worst I would unplug the tool and remove both brushes and with a flas light look into the brush tube while slowly rotating the armature looking for a discoloration or raised bar. If not you might bet by with cleaning the commutator with a special stone for this, you might be able to get one at the repair shop where you bought the brushes. If you want to send me the photo of the arcing it might help on my end. Let me know

hi Many universal motor malfunctions are caused by wearing down of the carbon brushes, the soft blocks of carbon that complete the electrical contact to the motor's commutator. When these brushes become worn, the motor will spark, and electrical contact may be incomplete.try this
Step 1: To sight-check the carbon brushes, remove the screws that hold the brushes and brush springs into the brush holders at the sides of the commutator. The screws will pop out of the screw holes; turn the motor over to tap out the brushes. The ends of the brushes should be curved to fit the commutator; if they're worn down, new brushes are needed.
Step 2: To check carbon brushes with a continuity tester, remove the motor lead wires from the circuit. Tag the wires as you disconnect them so that you'll be able to reconnect them properly. Hook the tester clip to one motor lead and touch the probe to the other lead; the tester should light or buzz. Slowly rotate the motor shaft, keeping the tester in position. If the tester doesn't light or buzz, or if it flickers or stutters when you turn the motor shaft, the brushes should be replaced. If the springs behind the brushes are damaged, they should be replaced as well.

Step 3: Replace worn carbon brushes and damaged springs with new ones made specifically for the motor. The model information (number and make) is stamped on a metal plate fastened to the motor, or embossed on the metal housing of the motor. If you can't find the model information, take the worn brushes and springs with you to an appliance-parts store to make sure you get the right kind. Insert the new springs and brushes in the brush holders, replace the brush assemblies, and secure the new brushes with the mounting screws that held the old brushes.

you may have a worn out carbon brushes on the motor.

pull out the motor and replace the brushes...

tnx 4 using fixya,

check the carbon brushes on the motor as when they are worn arcing occurs and this could trip the electric and the smell could be the plastic brush holders getting hot due to the arcing

if you can reach the blower motor, it could be a worn out carbon brush of the blower motor. if they are, buy a set of carbon brush, learn how to replace them and it would be back running in no time. by the way, when you pull out the carbon brush holder, make sure you dont interchange the position. you can put them back wards and what would happen is the rotation will be reversed. either you reversed the carbon brush holder or just simply interchange the wires that are coming to the motor. i hope i was able to help...
