I have a 2 year old Shopbot Buddy with a porter cable 7500 series router. Last week my router started making a lot of noise and smoking then blew a CCMR-15A fuse in the control box. I had to replace the router with another Porter Cable router and replaced the fuse. Today my machine ran fine all day then all of the sudden the router just stopped. The fuse was blown again. I replaced the fuse one more time and there was a small pop sound. I guess the fuse blew on more time. I checked the router with a heavy duty extension cord to see if it would even start up. Nope the router is blown again. What on my machine could be causing the routers to be blowing out like this? Who would I contact to get this looked at? An electrician? Any info a fellow Shopbot owner could give me would be much appreciated.
