How does the ice maker in a French door refrigerator stay cold enough to make ice when the top part of the fridge is just for cooling and not freezing?
In: Engineering
They just run some of the cooling lines to it, same as for the freezer section. Minifridges operate similarly. The “freezer” tray has cooling lines running through it to directly cool the freezer area and uses that cold area to cool the rest of the fridge to a lesser extent.
Worth noting that these [through the door icemakers in French door fridges are incredibly problematic](https://blog.yaleappliance.com/most-reliable-counter-depth-french-door-refrigerators). Many manufacturers have switched to an ice bin in the freezer and a water fill inside the fridge. Not as convenient, but if the icemaker is broken all the time that’s a bigger inconvenience.
I’m waiting for my French door fridge with broken through the door icemaker to finally die so I can justify spending the money on a replacement with ice in the freezer where it belongs.
The ice maker has its own separate compartment that is kept at a lower temperature than the rest of the fridge, allowing it to freeze water into ice.
That’s a great question! The ice maker in a French door refrigerator actually has its own separate compartment that is kept at a colder temperature than the rest of the fridge. This compartment is usually located in the bottom of the fridge, where the cool air naturally sinks to. The ice maker also has its own dedicated cooling system to ensure that the temperature stays consistently low enough to make ice. So even though the top part of the fridge is just for cooling, the ice maker has its own little freezer section to keep everything frosty.
