Just had a guy come in the shop and his new Derale dual fan controller wasn't turning on at all. Upon closer inspection, I noticed the temperature probe was stuck between the fins, but the cylinder it is attached to (that houses the thermocouple) was about a half inch from the radiators tubes. The instructions don't mention anything about that, but there is such a small area of the probe that's attached to the thermocouple housing, if there isn't enough contact area from the tubes to that small cylinder, the cylinder won't get hot enough to trigger the fan(s), or they won't turn on until a much higher temp.
You are also better off with the wire end of the cylinder facing the hot (engine side) of the radiator and the wire housing up against the tubes, not just the fins.
I wonder how many of those get poop canned or returned because of that?
