I agree as well Reno!
I have seen many a pool pump motor just cook itself from being out in the baking sun with their air vents clogged with debris. Same goes with the older style belt driven furnace motors. seen many of them fail from starting and stopping every 1/2 hour and being corked up with dust, not to mention being run without being oiled in years.

Yet, on the other hand our old General Electric furnace motor was the original from '67, ran hot and under a slight overload for years but was oiled and the vent slots vacuumed religiously. Also it was run 24/7 and was only off during power outages or for cleaning. It literally fell apart in '93 when I took it apart after we changed out the entire furnace. Pretty darn good use out of that motor if you ask me!
