I just rescued an old Hampton Bay fan and reinstalled it in my shop. It rotates clockwise only and there is no switch on the motor to change direction. It came with a remote branded "Westinghouse" so it may not be OEM? I have installed many fans and recall some changed directions via reversing a jumper, but I have no diagram. Also it would be quite inconvenient on this model, it came cladded with about ten pounds of ugly aluminum shell.

I know this has come up here before, and I even tried the flipping-power-while-spinning method to no avail. Which would be difficult anyway; it's 10' off the floor.

I would prefer not to guess at the right wire to swap, and doubt a diagram is available, so any input would be appreciated.

If the flipping power while spinning thing didn't work, either one of two things:

1. There IS a reverse switch on the fan and you just can't find it. This would explain why the reversing trick didn't work, if the reverse switch is hard wired, you can't fool it.

2. We already know it doesn't have the correct remote. So you may have to optain the correct remote for it, which would (possibly) have the reverse button.

It doesn't have pullchains, does it? Where is the receiver mounted?

No, as I mentioned, I stripped it down to the bare motor, there are only 2 small modules attached to the top surface- they are sealed and there is no external switch.

Yeah, that probably will do it, but since this project has been nearly free so far I was reluctant to do that. If I do, any recommendations?

No. At the moment, the receiver is temporarily wired at the top of the 8' pipe I am hanging it from. Works fine, the light too, just backwards. I tried running AC directly to the motor, no change.

Thanks for the reply! Any other ideas appreciated. Reversing a pair?

Looks like maybe a Capacitor and a Receiver. Swapping the correct 2 wires will likely change direction.
Some Older Fans didn't have a Reverse, so they made the Blades with adjustable pitch, You could get up or down airflow with out changing motor direction.
Just gave me an Idea for an Invention if no one makes them is:
Universal Fan Brackets that allow changing the blade pitch?

Right, any idea which pair?

Patent pending... :)

Not sure which pair, but someone good with these motors may know resistance test to help determine which pair.

This may help, looks like swapping 1 winding of the motor should do it:

You will need a Meter.

Thanks, first diagram I have seen. Not applicable here, but it'll be useful I am sure. I have seen many set up like these; just not mine.

Try swapping pink and yellow.

Made sense, that's how other motors seem to do it. But: no go, sadly. Might have to give up and take it to a local fan shop. :(

All 3 fan diagrams show reversing 1 winding to reverse direction, resistance checks should show 2 possible pairs to reverse?

Well, that makes sense- but each diagram specs both a speed switch and a reversing switch- this unit had neither.

It does, they are just hidden among the electronics. The reverse switch will be a DPDT relay with 6 wires going to it.

That's why you're going to need a Meter to measure the resistance of the wires coming from the motor, the windings have continuity with each one, bo no continuity between the windings.

It's a bit awkward to work on suspended, but I can give it a shot.

I would then eleminate any wires that are to the light. Then look for continuity between all combinations of the wires determined to be fan only.
If a bulb is in the light remove it to be sure you don't see that resistance.

None of the wires he mentions are for the light. Light wire would be blue or orange in a Hampton Bay.

I always advise against this sort of project.

If you can find the relay, then swap wires there. It may be solid state. Look for any place on the circuit board where 6 connections terminate.

Correct about the light. I also can't understand why this would be a big deal- or for that matter, why the fan seems to have been sold hard-wired for updraft in the first place...

It wasn't. The remote that came with the fan has the reverse button. Someone switched it to updraft and it never got switched back.

I can't stand remote fans.

You COULD just contact the manufacturer and buy the correct remote with the reverse button.
