My router (after 7 years) has decided to speed up and slow down. I checked the brushes and they don’t look that bad. Controller board?? Anyone got a suggestion?

probably, if the power is not cutting in and out.

No extension cord. Not much left but the controller I guess.
Top—power is steady. Router runs,just surges.
I can order a new controller for 75 bucks. Still cheaper than a new router. This one is in my router table on a rouseau lift. Got a lot of miles on it.

Thanks for the replys

Likely the speed controller.
It wouldn’t hurt to replace the brushes while you’re at it.

Come to think of it, try blowing it out with compressed air.

Also, there’s nothing wrong with using extension cords if you use a thick enough gauge. As an example, the only outlet in my shop is by the door; my workbench is on the other end of the shop. I never have more than two tools running and use a 25’ 12ga extension cord to power everything. No issues in 2+ years. I don’t want to upgrade the electrical because we’re renting.

Sounds like the armature assembly that controls the variable speed. I would talk with technical support at Makita.

Sounds like the potentiometer (armature) assembly that controls the variable speed. I would talk with technical support at Makita.

Had a similar problem with a Dewalt router, small magnet on top of the armature worked loose and lost all speed control. (This could be the ‘potentiometer’ as mentioned by JL).

Renners, that magnetic ring breaking on the 618 is a known problem dewalt refuses to acknowledge.
Both of my 618’s did the same thing.
