About the Casablanca C66U546B Receiver

A Casablanca C66U546B with a dead receiver still looks fine, but it will not move or light up on command. Replacing the receiver is a canopy job, not a new fan. This one restores six speeds, forward and reverse, and light dimming.

Confirm the motor housing label reads C66U546B before you order. The swap happens at the canopy, then it pairs with your RH787T.

Light on/off and dimming
Radio frequency (RF) control
Six fan speeds plus off for DC-motor fans
1-year warranty from our team

Do you need an electrician?

Not usually. If you can turn off a breaker, lower a canopy and reconnect wires the way they came apart, you can do this. If wiring is not your thing, an electrician can make the swap quickly.

Leave the wall switch on

The receiver needs power to hear the remote. If the wall switch is off, the fan will seem dead no matter how good the receiver is. A switch guard or a small label keeps people from turning it off by habit.

Before you order

Have the fan's power off at the breaker before you lower the canopy.
Not for AC-motor Casablanca fans or Casablanca 4-speed universal receiver systems.

Setup & Pairing

Turn off power to the fan at the breaker, not just the wall switch.
Lower the canopy of your fan to reach the old receiver.
Snap a picture of every connection before you unhook the old unit.
Make the same connections on the new receiver, check each one, and fit it back in the canopy.
Put the canopy back in place, then switch the breaker on.
Pair it: within 60 seconds of power-up, press Set on the RH787T, then let the fan finish its back-and-forth setup run of about 5 minutes.
Check off, all six speeds, reverse and the light.

Tip: a helper on the ground saves trips up and down the ladder.

In the box: One replacement receiver for the Casablanca C66U546B. The RH787T remote is sold separately.

Frequently Asked Questions

Will this replacement receiver for the Casablanca C66U546B fit my ceiling fan?

It fits the 1 model listed under Compatible Models on this page. If your model isn’t listed, call us at (816) 586-8457 and we’ll check for you.

What does this receiver control on the C66U546B?

Six fan speeds plus off, forward and reverse, and the light with dimming, all from your RH787T.

Will my old remote work with it?

Where is the receiver in my fan?

In the canopy at the ceiling, above the fan's downrod or mounting bracket.

What kind of signal does it use?

A photo of the old receiver's label and wiring, your fan's model number and your order number if you have one.

When will my order ship?

In-stock orders placed by 4 PM, Monday to Friday, ship the same business day.
