Replacing receiver on a ceiling fan, but receiver has fewer wires than the fan
I think the key is:


Motor 1
Motor 2
Motor 3


My hunch is that the old fan - and the remote controller - used separate connections for high/medium/slow speed of the fan. The new universal controller uses a single connection (line/neutral) with some sort of controller adjusting the current/voltage/waveform/whatever to appropriately adjust the fan speed. These two methods of control are likely incompatible. There is a small chance that one of the wires (either Motor 1 or Motor 3 - whichever one is "full speed") on the fan could be used with the new remote, but I wouldn't count on it working reliably &amp; efficiently.
