If you pour a little rubbing alcohol on your skin, it’ll feel cold — really cold. It isn’t refrigerated, so how does this happen? Well, alcohol evaporates at room temperature the way water evaporates at a low temperature in an oven. As it evaporates, it absorbs the heat on the surface of your skin, making your skin cooler. A special coolant called a refrigerant functions in a refrigerator the way alcohol works on your skin, except in a refrigerator, the coolant is trapped inside a series of coils. As it makes a circuit through them, it changes back and forth from a liquid to a gas.
the door is latched, and the control is engaged. If absolutely nothing happens—in other words, nothing on the control panel lights up and there are no other signs of life—the appliance may not be receiving power. If your dishwasher runs but doesn’t fill, either something is wrong with the water supply system or it is draining water too soon. If the water flow to the dishwasher doesn’t automatically shut off, the float switch is faulty, the timer is stuck on Fill, or the water inlet valve is stuck open.
