We installed this in June '23, in our kitchen. We mostly used it while cooking dinner, maybe 4-5 times a week, until late October. Not this year. It's been so hot some days we've been running the fan most of the afternoon (for ~8 hours). It made it through June, but start of July, it's become intermittent. 

To illustrate: when it's on swing, from middle to one end, it's firing up and at full speed by the end of its swing. By the time it reaches the other end of the swing, the motor's stopped and the fan's speed is just shy of full stop. Then it swings in the opposite direction, and the process repeats. When it's not on swing, it still cycles, just in one fixed direction.

Off the cuff, estimated hours run so far is 250-300 hours. If you ran it eight hours a day, every day, for five weeks, you might be nearing the end of the motor's life. I should've just gotten two box fans and hung them from the ceiling, because at least those would still be running.
