![]() ![]() Below is a simplified diagram detailing the principle. Increased spring tension can be felt as increased resistance when turning the coarse adjustment screw. Magic Chef 5.0 Chest Freezer - Unboxing & Review Longshores Outdoors 777 subscribers Subscribe 15K views 2 years ago Magic Chef 5. Thus, to adjust the thermostat to trigger at a higher temperature the opposing spring force must be increased. The important part is that to overcome manufacturing and material process variables and to allow use of the same design for different applications the spring tension is designed to be widely adjustable by manipulation of the coarse set screw.įrom the ideal gas law we know that at higher temperatures equal higher pressure against the diaphragm. The pressure sensor works by movement of a diaphragm set against a spring. The idea is that by sealing a quantity of gas in an enclosed vessel the variables V, N, and k are held constant resulting in the pressure of the gas being directly proportional to its temperature.įreezer thermostats use a long hollow tube as the enclosed vessel that is stuffed inside the freezer wall, with a short portion extending into the compressor compartment where one end is connected to a pressure sensor. Magic Chef Separate top freezer compartment allows for freezing your smaller frozen food items. Some units have them on the side, but I have yet to find one without a coarse adjustment screw.Įlectromechanical thermostats operate on the principle of the ideal gas law, PV=NkT, where P=Pressure, V=Volume, N=Number of gas particles, k=Boltzmanns constant, and T=Temperature in Kelvin. It is perfect for smaller spaces, especially in apartments, office break. Magic Chef 2500300019 Control Board, Refrigerator My Price: 95. STAR Certified Residential Freezers : Magic Chef - HMUF6WE.

What is not widely known is how these electromechanical thermostats work, and that these internal freezer thermostats have a coarse temperature adjustment screw which can be used to widely adjust the temperature setting of the thermostat, even above freezing to keezer temps. ![]()
