Mini Breaker Bad on Newer Unit?
Hi, I have a Power Star #99175. It runs for a while then trips breaker on unit. Has good vacuum, no plugged lines. I crossed switch at unit and watched it run. The motor doesn't get hot or smell overheated, and there is very little blue flash from the brush assemblies. I pulled them out and there is lots of length left on the brushes tho they were hot when I took them out but not discolored. Neither the reset switch nor other transformer get hot. Unit is 10 years old but hasn't been used much because cleaning service uses their own vacs. Any ideas? If brushes are bad, do you sell just the brushes? Thanks.. Paul in Wisconsin
