I bought this fan several years ago. I have the manual but cannot find the receipt. I know that the motor has a lifetime warranty. I pulled the switch for the fan and accidentally pulled it off. The fan won't work now. My electrician replaced the switch but it still won't work. The lights work fine. The remote works the lights but not the fan. Could it be the motor or what. Can I purchase a new motor. I really like the fan. Please help.
