I recently bought a Craftsman 27669 plunge router. The problem I am having is that after I plug the router up and go through the settings in the digital display. The router slow starts and go up to full speed ( I am assuming it's running at 25K RPM's) and then shuts it's self off and the display turns red instead of blue. I removed the top cover and checked all of the wire terminals and everything seems to be in order. Any ideas?
