In a video by @Techconnectify@mas.to, 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.
Yeah so they’re one unit, you turn it on and then choose to oven, microwave, grill or a combination of all 3. I’ve found combo low wattage microwave with oven to be great at quickly heating frozen food for example.
I think the major difference is that it’s rarer to have a combination stove and oven. The stove is usually separate and built into the counter top, similar to how a sink is installed. I have normal drawers beneath my induction stove. Then the combi oven is above the inbuilt fridge. Just whatever the designers of my rental place thought works well.
