>I do not know of any specific heat problem with the Fanzilla. I had >one fail but I was told it was uncommon. It's failure mode was to FWIW, last year I noted what I considered an unacceptable level of heat in the fuse area of my Fanzilla. I use the word "unacceptable" because the fuseholder caps were too hot to comfortably touch. The fundamental problem is that my R12 level is not correct, and the fans don't cycle when the AC is on, but I still don't think that amount of heat buildup should ever occur. Once everything cooled down, I inspected the fuses & holders and found that everything was clean & shiny. The caps have tabs that retain the upper half of the fuse. I bent these inward slightly to increase holding pressure & decrease resistance under load. The bottom half of the holder, IIRC, is a sort of multi-pronged affair that doesn't make full contact with the surface area of the fuse bottom. I know this sounds awful, but I simply dropped a small ball of aluminum foil into the holder so that when a fuse was inserted, it would flatten out & increase overall tension & contact area against the fuse. I also bypassed the cooling fan circuit breaker, as it seemed redundant to have 2 fast-acting fuses AND a (slow) circuit breaker in the cooling fan circuit - a simple repinning of one of the Fanzilla plugs accomplished that. I don't have the schematic infront of me, but if you look at it, it's pretty obvious what pin needs to go where. Result: A subsequent long-running test showed a dramatic heat reduction. The added resistance of the extra wire & circuit breaker didn't help the heat situation, but I think the fuseholders should have had a bit more tension & surface contact on them. A testament to the Fanzilla is that, even though it got righteously hot, the case did not distort or discolor at all. -Luke / 10270 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
