The motor on my expensive Casablanca Fan is only 2 yrs old. The circuit board is blown and I have to wait 60 days to get a new one, because everyone says they are back ordered from the factory. I think that means there are alot of blown circuit boards out there. The cost of the circuit board is running from $69. - $85., I did find one guy that wanted $125., I asked him why so much. He says they're in high demand. What a bunch of crap. I am probably going to go out and buy a new ( cheap ) fan, that will last a lot longer.
