Question about Porter Cable 690LR Router
Are you sure that there is no short circuit in the power cord itself? Have you tested to see that you do in fact have power to the switch?
If so, have a look at the brushes...Are they worn out and in need of replacement?
Blow some compressed air down through the motor and clear dust from the armature. Sometimes debris and sawdust gets inside these things and causes intermittent problems.
Do you have any cause to believe the motor itself has been subjected to the kind of loads that would cause severe overheating and lead to failure?
Any or several of these could contribute to a no power condition.
If none of these things apply, give the motor a couple of sharp smacks on the side with the heel of your palm. If there is a loose connection, sometimes this is enough to jar it into place long enough to get a partial power start up, and you can troubleshoot the loose connection. If not, it may make you feel a little better.
Otherwise, I'm afraid you may have a faulty motor. But these porter cables are workhorses. I rarely see them fail entirely. But it does happen.
I hope this helps you to diagnose the source of your problem and leads you to a solution. If there's anything more I can do to help, please let me know.
