I've run out of spares and am starting to explore repairing them as they fail. The FCC has the schematic's locked, but I thought I would check here to see if someone happened upon one at some time or another.

So far I've identified the most likley suspects.

If it has a Power Integration LNK model power supply controller.

I would look at the 6.8uF 250V and definitely the 100uF 35V caps.

With out seeing a schematic can't be 100% but it sure looks like a switching power supply and poor capacitors. Like in the 2413 PLM and some other Insteon modules. Where a questionable low voltage supply cap was used.

 

I'm not quite sure what problem you're trying to solve, but I found this thread a while back. I bookmarked it because I'll eventually be attempting repairs on a FanLinc that makes the fan hum on low speed. I only have one spare left. 

Hope this helps. 
 

 

I checked the output of the Red wire and I was only getting the negative voltage -60 volts AC 60hz. No change to the output signal when changing speeds. I took out the Triac (Q10) from the board and tested it and it seems to be fine. I think that the problem is the through holes for Q10 are not connected to the anything on the backside of the board. the connections are on the top where the package is. I am going to re-solder and check it. The caps were charging when I connected it to check continuity. Ill let you know. ;)

@kzboray, if you haven't noticed, FanLincs are back in stock.

@Bumbershoot I did! Thank you! I have actually been able to repair three over the last few months and have parts on hand for a half dozen more so I'm set for the moment, but I'm looking forward to I hope an updated version that doesn't use the low quality components that the current ones use.

All the ones I've repaired simply needed a new triac or cap. I always replace all four triacs and all the caps when I update them.
