I have a Hunter Lugano Ceiling Fan #28111. The remote receiver (85661) is bad.

This fan has no external switches, pull chains, etc. It's designed as remote control only.

There are 9 wires coming out of the remote receiver. I know what 5 of these wires are doing. They are: (two) AC hot & neutral - input to receiver. (two) output for the light. (one) antenna.

There are 4 wires going into the motor - RED, YELLOW, GREY and PINK. I'm assuming one is common and the other 3 are for: LOW, MEDIUM and HIGH Speeds, as it's a 3-speed motor.

The problem is: Nobody, including Hunter Tech Support can tell me which of those 4 colors, go to what part of the motor.

I'd like to bypass the receiver and hard-wire an external wall switch. It has 2 controls - an infinitely variable light dimmer and a motor speed control, with 5 positions: OFF, MAX, HIGH, MED, LOW. There is only one hot wire from this switch, going to the fan (and obviously another hot wire going to the light).

If we can figure out which 2, of the 4 wires going into the motor are COMMON and HIGH, will the 4-speed external wall switch run the fan on all 4 speeds and off?

NOW, THE REAL QUESTION: How to figure out what the 4 wire colors, mentioned above (going into the motor), are doing? What's COMMON and what's HIGH?

Yes, I realize I'll have to run an additional wire from the wall switch to the fan.
Thanks in advance, for any REAL advice.

I think it would be wired something like this:

It is probably a coincidence that the colors shown are the same as yours...I would double-check using an ohmmeter.
Assuming RED as the common, you should get progressively higher resistance as you go RED-YELLOW, RED-PINK, RED-GRAY.

You'll know which 2 wires are candidates for the common because they'll have the highest resistance between them. Then hopefully something else in the fan will rule out one or the other and you'll know the common, and can figure out the rest using the resistance values.

Based on this diagram from a different source, the common wire MIGHT be the one with the highest resistance to every other wire, but no guarantees here.


So, using the diagram above, if you don't know which is common, make a resistance table:

OHMS	Brown	Red	Blue	Black
Brown	-	108	133	369
Red	108	-	25	261
Blue	133	25	-	236
Black	369	261	236	-

Since Black has the highest reading to ANY other wire, it would be the common.

Since you just want common and highspeed, you'd take your common (once determined) and the wire with the lowest resistance to common. In the example above, that would be the Blue wire @ 236 ohms. (Whether that will allow the switch to select the fan speed, I do not know)

I hope this helps, but sadly I cannot be responsible for what might happen!

Wally,
Thanks for your reply. Unfortunately that's not the proper answer for my type of fan motor.

What I discovered, is that these types of motors have 2 independent windings. So with the 4 wires going into the motor, 2 go to the 1st winding and the other 2 go to the 2nd winding. There is infinite resistance between the 2 windings. Both windings have similar resistance.

One of the windings REQUIRES a 5mfd capacitor to be in series with the 120 VAC input. Lets call that winding #1. By reversing the polarity (hot vs neutral) on winding #2, you reverse the direction, the fan spins.

To use either a universal remote receiver, with 3 output wires (NEUTRAL, FAN & LIGHT), or an external switch, that has a 3 or 4 speed motor control, here's how to do the wiring (The wire color codes I'm using, appear to be used on a variety of different motors. YRMV - USE CAUTION):

FOR FAN DOWN-FLOW DIRECTION:
RED – WINDING #1 – NEUTRAL – NEEDS 5mfd CAP, IN SERIES
GREY – WINDING #1 - HOT

YELLOW – WINDING #2 - NEUTRAL
PINK – WINDING #2 – HOT
REVERSE THE PINK & YELLOW POLARITIES, FOR FAN UP-FLOW DIRECTION.

Regardless of the direction you want your fan to spin, NEUTRAL goes to both windings, with the 5mfd cap in series with winding #1. HOT (coming from your fan speed controller) goes to the other side, of both windings.
