Has anybody have a Derale fan controller die on them?

[Hannibalzero]

I'm not sure why, but it seems my Derale has burnt out. The fuse looks fine (but I will try another just in case). The wiring has not changed. The 12V and ACC sources should still be working (12V from the battery, ACC from the wiper motor). I'm going to hardwire the fans to run constantly to verify that they work, but I doubt both would die at the same time.

Has anyone else had a problem with the Derale Controller?

Yep i had mine fail on me. Caused the temps to spike quite a bit. Not sure why it failed but right now my fans are just hotwired with ignition on. I may try a more expensive fan controller with more features in the future. I think HKS makes a pretty good one

Glad to see I'm not the only one. I still haven't determined that the Derale was the point of failure. Its possible, though not likely, that both fans failed at the same time. I won't know until I try to hotwire the fans. Hopefully that will happen this evening, but its hard to say. I'm stuck in Nashville working LONG hours this week.

so far so good with mine.

yup - worked for a solid week! that stupid fan/overheating shit was the only major setback i had doing my tt conv.

My 2 guesses for failure are overheating the control box or it getting water splashed on it. I had mine mounted right on the fan shroud so it may have gotten pretty hot.

My control box was located under the fuse box. I would not expect that to be exceptionally hot. It is away from the front turbo, and probably won't see as much heat soak as it would on the firewall. One would certainly think that under the fuse box would protect it from the very light rain the car has seen over the last two weeks. Although I have been drinving a hell of a lot lately (2,200 miles on 14 day, I still wouldn't expect a fan controller to die out after 3 months and under 5,000 miles.

One week? Ouch. Did Derale replace the fan contoller?

Played around with things today. I replaced both the relay and the fuse and the derale still did not work. The fans work when directly connected to a 12V source, so I contacted Summit racing. The fan controller was 1.5 mons old, so I wasn't sure they would take it back. Fortunately, they wew very helpful and agreed to send out a new fan controller ASAP on Monday.

good to hear - i ended up taking my car to a mechanic b/c i knew I had everything setup right, and he ended up ditching the fan controller and hotwiring it.
