Hello. I have a Makita 3612C (3 1/4 horsepower, variable speed) that I need some guidance with. Earlier today I was doing some easy routing when all of a sudden the router speed changed, I saw some orange sparks inside the router, and the circuit breaker for the outlet I was using popped. The tool was smoking and emitting the typical burnt electrical smell. After I reset the circuit breaker, I did not run the tool again, fearing I might damage it more. My question is: is the router salvageable? I took it all apart and everything looks ok; the brushes are hardly used and nothing looks burnt or melted. I've read a few posts that say the speed controls on these routers are sometimes the cause of this type of problem. I can replace the speed control for $85. Is there any way to check that the field assembly or the armature assembly is good before I buy a new speed control? In case it isn't obvious, electrical troubleshooting is not my strong suit. I don't want to sink money into this thing if there are multiple parts that are going to need replacing. Thanks in advance for your help.
