In a video by @[email protected], Alec goes into a deep dive into the simplicity of his particular model, its shortcomings and variety of data logging tests in an attempt to fix them.
TL,DW: Very simple, cheap and ingenious design, with one compressor loop between the fridge and freezer in series. However, its temperature sensor is wonky and so the fridge is more affected by how long the compressor operates than the actual temperature itself. There is a signficant temperature differential between the top and bottom, fans on the exterior or interior could help but with the faulty sensor only made matters worse. With the controller replaced with a proper temp control unit the fridge functioned much better.
I used to think dishwashers were kinda rubbish before I watched his video and learned how they actually work and the best way to use them. I recommend that video to lots of people now. Great channel.
He became one of my favorites after he got me to enjoy a half-hour video on storm lanterns. Dude has some serious charisma and really good investigative skills.
