Having been an infrared thermographer for many years, this was possibly caused by loose connections. I would recommend installing IR windows over all connection areas where possible. This would allow future inspections using an infrared camera while the unit was under load.

Thanks for the tip! I've seen some installations with that setup. It's a great idea!
