Casablanca Vary Quiet PC Board for Series 4000
First, the resistor you are looking for is a 39K ohm +/- 5% tolerance (GOLD tolerance band). Second, FAN MAN still has a couple of new boards in stock, even though his website says he is sold out (I just spoke with him today). VERY nice guy, and VERY reasonable prices. Phone # is (866) 600-FANS (3267). I had the same problem a few years ago (burnt resistor and fried pot) and replaced the resistor and pot. Everything worked again with very little time to fix, and almost no cost. Got the resistor at Radio Shack, but had to order the pot from a Casablanca dealer - read on.......
Now for the pot......
Part #1954150 *IS* a 5K ohm linear taper. I'm looking at the meter and a new pot as I write this. You had me wondering if I misread the meter or something, so I went back and double/triple checked. This pot is installed in my recently rebuilt Vari-Quiet Victorian, and it works fine.
However, I want to tell everyone that I had purchased a replacement pot many years ago from a Casablanca dealer because, as I said above, my old one had fried, along with the resistor (just like your situation). The pot the dealer sent me was a Casablanca part 0001040 (I still have the receipt), and it fit perfectly, so I didn't pay much attention to it. This pot worked for over a decade. But the replacement pot was NOT stamped with the 1954150 part number, and I have long ago thrown out the original - so I don't know at this point what was originally in the fan. BUT, the replacement pot that I put in so many years ago *IS STAMPED* "25K Ohm", and I measured what is left of it and it definitely is a 25K ohm linear taper pot. It worked for over a decade (since 1998).
Now, I have once again rebuilt my fan this summer because the pot again failed (I can't complain, I got almost 11 years out of it). New bearings, new pot, new flywheel, new PCB assembly, new heat sink/transistor, new brass hardware and a a coat of paint/laquer (brass). The new pot was purchased from Plaza Lighting (978) 774-7801, Don Guerette - another VERY nice guy with EXCELLENT prices. However, I got his last pot - sorry. The pot Don sent me is the 1954150/5K Ohm linear taper - the same one that came out of your Vari-Quiet. It also works very well - better than my old 25K Ohm pot because it slows the fan to a full stop at almost a full deflection of the knob (my old 25K ohm slowed the fan to a full stop at partial deflection).
Hence, my conclusion is that the part that belongs in MY fan is the 1954150 pot, and the 25K Ohm pot was the wrong one, even though it worked for many years (no reason it wouldn't, scaling was off, that's all). If you've never done anything with your fan since new (like replace the pot), then the correct pot is the 1954150 since that is what you are taking out of it, and that is definitely a 5K ohm linear taper. You can pick these up almost anywhere. The 25K ohm wa a wire wound. I don't know about the 5K ohm as I'm not about to take mine apart - smiles.
P.S. I was able to acquire a W52 remote control module and install it on my rebuilt Vari-Quiet. It works GREAT (Casablanca sasys you must convert it to a 3-speed before you can use the W52 - LOL)!!!!!
