More Problems w/ Casablanca Vari-Quiet Zephyr Fan

[cchiang1]

Hello:
A few weeks ago I posted a question regarding the resistor value on a burned R1 on the Vari-Quiet circuit board of my Casablanca Zephyr ceiling fan. I followed the advice and replaced the 33 ohm resistor and the NTE 162 transistor on the heatsink . The other components on the pcb seemed fine, but the potentiometer was burned up. Not knowing it's value, I bypassed it by connecting its two red wires together. When turned on, the fan ran on a very low speed okay, but the R1 resistor burned up again as soon as I turned the speed up to maximum. (BTW, I've never used the variable speed control knob or pull switch mounted on the fan since I bought the house with the fan installed 7 years ago; I use the wall-mounted variable speed / light dimmer knobs). I've read in other posts, that the vari-quiet bd. is difficult to successfully repair, and mention of a 3 spd wall-mounted replacement option. Questions--

1. Was is okay for me to have bypassed the potentiometer, since I was using the wall-mounted control? If not, what is its value?

2. What other components should I check or replace on the fan? Besides the ruined resistor, should I replace the transistor again?

3. What is this 3 spd controller replacement option, cost, etc? Does it bypass the vari-quiet bd.? Since I already have a similar wall-mounted variable speed device installed, is there some way that I can bypass the fan's circuit bd. myself? (I presume some of the components like the large capacitor, etc. are needed to start the fan motor).

4. I prefer to keep this fan, since it's already installed and others have mentioned that it's a good quality fan. However, I have other unused ceiling fans I can replace it with, as well as another Zephyr (without the troublesome Vari-Quiet bd.) that is currently being used elsewhere in the house. If I have to give up on this particular fan, does it have any value for parts, etc.?

Thanks in advance for any help or advice!

The pot is 5k 1watt. Bypassing the pot is the same as putting the fan on high and should not have caused problems. Really, since you have a wall control, you'll want to bypass the whole slumber quiet system. Normally you can do that by just shorting the pot, but it this case you may have to short the entire board. You'll need the 10uf capacitor off it and the reverse switch.

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

Hi:
Sorry, but I'm having trouble following your directions. I have white a& blue wires that go to the light fixture, and black, red, and brown wires on one connector going to the PCB (120VAC between black & red, and black & brown wires). Ignoring the pull chain switch and pot, that leaves another connector with blue, green, and yellow wires. The reverse switch has a black wire to the center terminal, and red & white on the ends. I understand the function of the reverse switch (black wire switches to either red or white to reverse motor, and you say the 10 uf capacitor connects to the red and brown wires, but which wire is "Neutral", what color wire goes to the center terminal of the reverse switch, and what do I connect the blue, green, and yellow wires to *exactly*? Thanks.

ignore the blue green and yellow, those go to the transistor. We are dealing with the rest of the wires.
