The GE 3ART Series refrigeration and air conditioning thermostats provide a wide variety of controls designed specifically for refrigerator, freezer, air conditioner, water cooler, dehumidifier, and other appliance applications. Generically, the thermostats are referred to as vapor pressure operated electrical switching controls. These controls derive the power to operate the switch from changes in pressure, caused by changes in temperature at the capillary tube sensor. GE thermostats are available in either constant temperature differential, or constant cut-in, variable differential models. Alarm signal switching for freezer applications and ''off switch'' also are available.
