Original Hunter Receiver is no longer available and is replaced by The Anderic FAN2R Kit. (You have to buy the kit that comes with the remote because the original hunter remote will not work with the FAN2R receiver.)

This is a genuine Hunter replacement part, it is sold individually.
This Receiver is in a number of Hunter Fans.
It is controlled by the 8509501000 Hunter Remote.
It controls the light and the speed settings of the fan.
