One of my Kessil lamps is having problems with the cooling system. It's physically hotter to the touch on the casing than my other two A350s. It's been periodically shutting itself off today, I believe due to heat buildup. Does anyone have experience repairing the cooling system? Does Kessil offer any kind of service or repair? I reached out to their contact e-mail but did not get a response. Any help is appreciated.
