I've owned countless refrigerators in the last 40 years, and NOT ONE SINGLE ONE WORKED RIGHT.........
That's right....NOT ONE. The freezer doesn't freeze properly, while the fridge swings wildly from too warm to freezing. You get things balanced out decently, and a week later your ice cream melts, or your salad greens freeze.
I can't be alone in this frustration.......can I? My big expensive side by side is just as bad as every other unit I've owned.
Here's what I propose doing. This fridge operates on a sensor in the refrigerator compartment, does it's cooling in the freezer compartment, and a "valve" allows a percentage of the cold air to enter the fridge. You adjust the freezer temp according to how much air you allow into the fridge, and you adjust fridge temp with the thermostat. This is a pretty much universal method of operation.
I intend to install two PID controllers..... One in the freezer and one in the fridge. The one in the freezer will control freezer temp by turning the compressor on and off. The one in the fridge will control refrigerator temp by turning a fan on and off, bringing cold air from the freezer to the fridge.
This will allow me to set the Hysteresis for the variation I want... 1 degree or 20 degrees, or 3 degrees.
Is this nuts? I don't think so. I've finally come to the conclusion that if I want something to work right, I'm going to have to build it myself!!
