LED retrofit kit keeps turning off

I realize this post is 7 years old, but we are (have been) experiencing the same OtP issues with a couple of our Source 4WRD units. We didn't realize the problem was overtemp until this past week when we were doing some refocus/maintenance on them. We had always assumed it was a power issue. Any way, 4 of our 12 units were purchased a year or so before the others and it seems like those are the ones with this issue. We currently have 2 that flip to OtP immediately, 1 that occasionally flips, and 1 that seems to be behaving fine. We also have a different SFWD unit that is broken in a different way. I didn't see many options for contacting support, so I figured I would try this forum. 

This has always happened to me upon first powering up some Source 4WRDs from a preset that brings stagelight to Full.

If I fade the trouble fixtures up to 100% over a longer time period, say up to 80% for 5 minutes and then any brightness after that, I don't get the overtemp error and loss of light.

My assumption is the cooling system isn't starting up right away after the electronics go to sleep. So the slow warm up period allows the cooling system to startup before the element overheats and the sensor tells the fixture to shutdown. 

They advertise the source 4wrd as having an advanced heatpipe system. I've read reports that it's essentially an ultrasonic membrane that pushes liquid through the LED element through pipes into a radiator, which is why they say it must come up to room temperature if exposed to freezing conditions. 

Then I also found this article saying there were issues with early models having cooling problems due to a faulty part. http://www.lightingandsoundamerica.com/news/story.asp?ID=-R5LDZN

I think I was an early adopter and may have one of the troubled fixtures, but am far past any warranty period for replacement, so I deal.
