I had a similar Lasko fan. It was remote control. The motor would screech and eventually slow and bind up. Three times I disassembled it to get to the bearings and greased them up with moly grease. It worked for a few weeks each time and then failed again. I got maybe one extra year of use out of it and finally threw it away.
Yes, I know what you mean. Sometimes, I wonder if it's worth it. I've had to steal wool the shaft before it gets a little corroded. I appreciate your comment.
