15 years wasn't good enough for you, so you bought the upgraded model the second time? lolIt depends on your fan controller. Most of them have a terminal for activating the fan(s) at 50% or so to keep air flowing through the condensor. I have found that the Flex-A-Lite fans are very long-lasting and reliable. Their controllers, not so much. I had one of their controllers on my fans for about a year, after which it failed (right after warranty expiration, of course). Bought another one, didn't work right out of the box. Returned it. Bought a controller from Direct Current Control to run fans. First one I bought was a FK-35, which lasted 15 years before failing. Bought a FK-45 last time around, works great.
My setup was purchased with a new radiator in 2006, so no chance I got a newer model.I had the same experience as MoparMarq. Fan controller died after a short time then upgraded it. Depending on your model, it may be better than their older models. Mine was new about ten years ago.
Another failure point is the supplied fuse holder in the FAL kits. Mine melted on day two. So, save yourself some trouble and upgrade that on day 1.
Well, specifically, the Flex-a-Lite controller was a bad move on my part. The fans themselves have run flawlessly for over 15 years. Flex-a-Lite model 220, if I remember correctly. That model fit pretty well over the stock radiator, and later, the aftermarket radiator, when the stock radiator gave out. Had to make some custom brackets for the fan shroud to fit to the radiator, but the core coverage is near perfect. And parts are still available for the fans on Summit; motor and blade assemblies, IIRC. I bought new blade assemblies a few years ago when I had a mounting mishap. I didn't mean to bash the fans. The fans are a good unit; at least they have been for me.Further, the Flex-a-lite is called out by name. Not a good start.
