Replace casablanca rmm control board w/ cheap?

[netmammal]

I've got two Casablanca fans with bad RMM controller boards (the other end of the W-32 Intellisense switch). One board is totally gone, the other I'm told (by Casa-tech support) is on its way, it will not dim/shut off the light, you have to use the power switch instead.

Since the both of these boards blew after less than 5 years of ownership, I have no interest in staying on that $400+/decade treadmill. I love the fans, hate the controllers, (and their support too for that matter--they take longer to answer than 9 outta 10 tech support calls I make.) Oh and the second board blew after I had a whole-house surge protector installed, so those blamed things are just too sensitive in my own experience-- maybe I have just been incredibly unlucky. BTW, get one of these whole-house surge babies, *everything* electronic lasts longer, including lightbulbs!

Anyway, I've been trying to figure out how to replace the controller with one of those cheapo hampton bay remotes (with a themostatic function I want) from home depot.

I can not find a wiring diagram to save my life for this motor, which I presume is a K-55 knockoff called XLP-200 I think. I'm looking at white, brown and red wires going into the motor. I'm guessing I'm going to want to scrounge the 10 Mfp cap off the controller board, and maybe route the power through one of the resistors wrapped around the motor. I don't care if I can't get the thing up to the 8 gazillion RPM its capable of, I just looove the really slow speed its capable of, so the resistors will take some experimentation.

The remote only provides line and neutral, so I'm guessing I hook the extra wire up with a cap attached. Looking inside the new controller, its got a bunch of smaller caps. Not sure how that plays.

Has anyone done this before? Does anyone have a guess how to do it? I'll try anything as long as it does not risk damaging the motor. (I'm a software guy, not a hardware guy!)

Thanks in advance!

First I will warn you-- the hampton bay remotes will last MUCH shorter than the InteliTouch electronics. Really the most reliable thing you can do is hard wire the fan to a wall control. The second most reliable would be repairing the InteliTouch. It's really rather rare that they fail, you had a murphy's law experience.

You wont need anything off the board except the 10uf capacitor. Do you have any interest in being able to reverse the fans?

[netmammal]

Thanks!

Actually, if I lost the reverse, it would not bother me. We never use it.
Tell me what you know.

Cheers,

There are only 3 wires coming out of the motor. The capacitor connects to two of the wires, and power applies to one side of the capacitor and the remaining wire. If you have an ohmeter we can determine which side is which.

[netmammal]

Sorry for the delay, I forgot to come back and look (I'm used to forums that e-mail you.)

I think I'm missing something from your description. I've got the Ohmeter, but not sure what wires
we're looking at.

HHHHHHHH--cccccccccap

If 1, 2, & 3 are the motor wires, and N & H are neutral and hot, is this what I'm looking for?
I'm showing 1 & 2 joined with one leg of the cap, and the 3rd wire going to neutral.
What do I measure to pick which wires end up being 1, 2, & 3?

Thanks!

P.S. Sorry for the ````, for all of the formatting options, I can't figure out how to retain extra spaces, and the on-line help is for neubs only.

Your wiring makes no sense to me. Can you take a picture of it?

[netmammal]

No, that diagram is me trying to make sense of your explanation. As far as I know, there is nothing weird to the existing wiring.
Its three wires coming out of the fan motor, and two wires coming out of the ceiling. When you wrote
"The capacitor connects to two of the wires, and power applies to one side of the capacitor and the remaining wire."
this is what I thought I heard.

I could not tell what I was supposed to connect neutral to. Here is what I think that meant:
Splice wires 1 &2 and a short pigtail, and then solder that pigtail that to one leg of the cap. Hook the other leg of
the cap to hot coming from ceiling. Splice wire 3 with neutral coming from ceiling.

Was that right?

Thanks!

By the way, I went back and re-read the whole thread just now, and you mention repairing the Intelitouch. Did you mean actually diagnosing and repairing? That would be great, if I did not have to buy a new board. I might be able to
ply a electrical engineering pal with libations to convince him to look at it, I just assumed that there was a good chance
that it was one of the chips on there was bad, and that they are not replaceable.

The three wires coming out of the motor, are they red, brown, and white?

If you want to have an electrician take a look at the IT, by all means, I just replace the whole board or convert it to 3 speed.

[netmammal]

Yes, the wires are white brown and red.

I need the impedance between the 3 wires, although I can already guess which wires are which.

Brian and I just went over this, see if this helps:

mt_spiffy (10:24:30 PM): Capacitor connects to red and brown
mt_spiffy (10:24:39 PM): neutral connects to white
mt_spiffy (10:24:50 PM): and the power connects to either red or brown depending on which way you want it to go
mt_spiffy (10:24:54 PM): the reverse switch determines that
mt_spiffy (10:24:57 PM): it's just SPDT
behfanwiz (10:25:37 PM): and the reverse switch connects to the red and brown
mt_spiffy (10:25:53 PM): the sides of the reverse switch connect to red and brown
behfanwiz (10:25:55 PM): the outputs of the switch connect to there as well as the motor leads, correct?
behfanwiz (10:26:09 PM): and my incoming speed control power connects to the center terminal of the reverse switch

OK, I have a fan with the same issues and I'm wanting to convert it to a 3-speed pull chain. I understand the last post above. But how do I do the three-speed part?

Thanks.

Ok you can either buy the three speed kit from Casablanca (then disregard the last post), buy a 3 speed pullchain and capacitor and install those (will take some experimenting) or take the above directions and use a 3 speed wall control.
