I have a "Harbor Breeze" ceiling fan. Recently I noticed the remote "red dot" light came on and stayed on, this light usually came on when a function button was pressed. I thought this meant that the battery was low so I changed it. The red light came back on immediately, and the remote would not control the fan. The model # on the remote is UC7080T. Does anyone know if the remote is bad or not? Also, where can I purchase this remote if I need a new one?
