I had this fan. It lasted only a couple of
years until the motor burned out. Now it’s trash. Bummer. When it squealed, we thought maybe dust? It was clean. Maybe oil? So we oiled it up. It lasted one more night. The squealing started again and it smelled like it would be trouble. I had a floor model that behaved similar and it blew up with sparks in front of me. So, we weren’t taking chances with this one. Goodbye favorite fan.
