I've got three of the original hunter fans (cast iron) I purchased around 1981.
The fans are two speed. The low setting for the fan is to high for the bedrooms.
QUESTIONS: 1) Can the fan be rewired or a resistor put in line to reduce the speed -- if so how?
2) I would like to move the fan and light control from the original pull to the wall. I prefer a separate fan control (a combo light / fan is OK but not preferred) but the fan control needs to fit into a duplex box with another switch.
I understand solid state controls and variable controls "supposedly" have problems with these fans. Any suggestions for controls (solid state or otherwise) that are wall mounted and will work with these fans would be appreciated.
Thanks David

You can wire a capacitor in series with the lower speed to make it a 3 speed fan. You will also need to replace the pullchain. I cant remember what value capacitor you need but someone here will remember.

I would just wire the fan and light separately on a wall switch for the light, and a ceiling fan speed control on the wall for the fan, and the fan's pull set to high at all times..

Thanks both for responses:
Re:
What fan speed control -- make / mode - do you recommend?

Hunter Originals are the exception to that. You can use them with a solid state control, but it is noisy, and regular controls wont work. You can get a special capacitor based control for Originals but they are for newer PSC Originals.

If you go the capacitor route you will need one between around 10 and 12uf and wire it in with the LOW speed wire. The new pullchain needs to be L+1, L+2, L+3, off. L goes to the lead wire, 1 goes to high, 2 goes to a wire connected straight to the original low, 3 goes through the capacitor and then to the original low.
Generally I have found anything lower than a 10uf isn't powerful enough for the fan to start on its own on low, while anything higher than 12uf and might still give you too powerful of a low for your room (and too close to the original low). However, those motors came in various amp ratings and therefore the capacitor values you are able to use may vary.

Thanks All.
My primary objective was to get rid of the pull chain and go to a wall switch.
I had hoped this thread would ID the right wall control as everything you state Spiffy is what I've heard / read. My assumption is since the control has a built in CAP that one would not be needed to operate the fan at a lower speed -- (the pull chain route). If NOT, a separate CAP could be installed in the housing -- ?
Not sure what a PSC Original is -- What does PSC stand for -- ? [/quote]

PSC = permanent split capacitor. It's a type of motor. 3 speed Originals are PSC. 2 speed Originals are shaded pole. They make silent wall controls for PSC Originals, the only wall controls they make for shaded pole Originals are the noisy solid state ones.

"Spiffy"
Glad I asked. There is a fan manufacturer named PSC (similar to Emerson Motors). Hopefully I can locate a wall controller based on this new info.
Thanks

If Brian Hicks shows up he can tell you more and maybe correct me, however:
The only control that will work with your shaded pole (NOT PSC) Original is a solid state control which will be noisy. You could make your own control with capacitors.

Spiffy:
Any schematics available for making your own control?

You need a bunch of different capacitors to try values until you find what you like. If you dont already have a big box of capacitors, it can get expensive.
I made mine using a rotary light control-- 1, 2, 1+2 and an on off switch. So it requires a two gang box. Unless you can can find a 1, 2, 1+2, 3 rotary switch which is what a premade control would use.

I have a bunch, both standard and electrolytic. Whether I have the right combinations of values is yet to be determined. Found several schematics online but used triacs.
From my reading, getting the correct values is critical so you don't burn up the windings or overheat the varnish on them. Supposedly solid state controls cause these issues.
