Ceiling fan with remote control and 2 wall switches

What you propose is indeed possible. How difficult it is, depends on what wiring is currently in place.

You should start by connecting all the bare/green grounding conductors in the switch box together, including a pigtail to both switches. Other than that, it sounds like the wiring in the switch box is good to go.

If you want to control the fan with a wall fan control, you can install that in place of the fan toggle switch.

In the ceiling box, you'll likely find the 12/3 cable from the switch box. If the existing fixture uses a remote module, you'll likely find that either the black or red wire from the 12/3 cable is simply capped off. You'll see the black/red, white and ground wire connect to the remote module. The remote module should connect to the fixture with a black, blue, white, and bare/green wire.

If you want to remove the remote module, you should disconnect it from all the wiring. Once disconnected, you can remove the module, or cap off all the wires and leave the module in place.

To control the fan using only the wall switches.

• Connect the white wire from the ceiling to the white wire from the fixture.
• Connect the bare/green wire from the ceiling to the bare/green wire from the fixture. If the box is metal, include a pigtail to the box.
• Connect the red wire from the ceiling to the blue wire from the fixture.
• Connect the black wire from the ceiling to the black wire from the fixture.

Now the switch connected to the red wire, should turn the light on/off. The switch connected to the black wire, should turn the fan on/off (and optionally adjust the speed).

First, check that you have the batteries installed in the correct direction in the remote. Some use both positive buttons up, some down, and some one of each.

Second, check that the remote and fan do not have a channel switch. These are usually mounted horizontally on the fan and are frequently labeled A/B or 1/2. If there is one, the fan and the remote must be set to the same value. It doesn't matter which one, use the one that works best in your home. Make sure the fan is turned off at the wall before changing this setting.

If that doesn't work, remove the lighting assembly and verify that the controls are connected in the space behind it. There are generally three screws around the edge of the plate where the lights attach to the fan. It may be helpful to have a second person safely assisting you. The colors there are generally white, black, and green that match the connections above. Red and/or blue may be used for the control wires in there as well.
