I have 2 wall controls for my current fan. One is for the light on the fan and the other is for the fan itself. When I disconnected the old fan, there were 3 wires - black, white and red. What do I connect the red wire to? When I connected my new Hunter fan, I did not connect the red wire and it does not work.

controller switches are changing every day
there are available a variable speed unit that alters the sine wave so you have any speed you like
Talk with a fan shop or qualified electrician as they are easy to install and are as cheep as the others

Probably has A BAD RECEIVER.
What make/model of fan is it. If it's a store brand take it back.

You can use a remote from Home Depot, where the fan was bought. Reverse will have to be done manually at fan.

You get what you pay for! Shouldn't buy a store brand.

Not sure, but if its a new installation, I would say that the wiring has been done incorrectly. Ceiling fans with lights should be able to work independently. both on / off or 1 on, the other off.

You are exactly correct...

Power flows to the fan as soon as the circuit is closed.

All the light (diming) and motor power, speed & reverse are all
controlled by tones from the switch to a receiver inside the fan housing... (only 2 wires + ground).

I have BOTH (the old style 3 switch) and the newer 4 button "W32" ... use the same tones BUT ARE NOT INTERCHANGEABLE...

In my opinion
The premier site for ALL FAN switch troubles
is the "FAN-MAN" (see below).

Store fans use low-end components. Try getting a better remote & not from H.B.

Check all connections where any power wires or ground wires are connected. Even on the switches. and yes on the fan itself. Sometimes a wire on a connection will vibrate loose and will work then not work. Make sure they are tightly put together.

Never use the dimmer switch for ceiling fan.

the reset is probably an inline circuit breaker. if you can get hold of am amprobe clamp around ammeter, check the current when the unit is running at full power. the reading you get check against the current rating of the inline breaker. your fan motor bearings may be dry increasing the current draw of the unit and tripping the breaker. try oiling the fan bearings with a light oil NOT WD-40.
