the model number of the fan will be on the top side of the motor.
when you press the remote does the light on the remote go on?
ok so the remote is sending a signal out ,sounds as if the fan is just not receiving the signal ,
which will be the fan receiver.
Here is a link to Hampton Bay .
It is the Home Depot Hampton Bay parts line at 1-877-527-0313. They will be able to send you the parts. Just have your model number ready.
I would think they are closed on New Years eve.
