I know many on here use Lighthouse motors for their vac system, and many have had failures. I have 4 motors mounted outside under a covered area. 2 of them are the primary ones that I use 80% of the time. The other the are secondary, and I really only use those when I need a boost.
One of the secondary motors failed the other day. I know the main failure is due to heat, but two other motors have many more hours, and I haven't had a problem.
My question is what happened when yours failed? Was it heat or something else? With mine, the impeller sheared into several bits inside the housing. The motor itself will still run. I don't feel like it overheated, but what else could have happened?
