Pressure Imbalances

Understanding pressure imbalances is crucially important to troubleshooting all kinds of appliance problems, from a dryer that's not heating well to a refrigerator that is freezing your veggies.

Water will always move down hill if it is able as an effect of the pressure imbalance caused by gravitational energy. 

Weather systems move and swirl around the globe due to imbalances largely caused by differences in temperature. 

Electricity will attempt to equalize any imbalance in voltage by moving from an area of high electrical charge to a ground or neutrally charged source.

Heat will always attempt to equalize any temperature imbalances by my moving to cooler areas. 

Electromagnetic Radiation (Light, X-Rays, Radio Waves, etc.) will always attempt to equalize any radiation imbalances my moving to less active areas. 

The laws concerning these equalization effects are so reliable and predictable; they are used for anticipating weather patterns, engineering every appliance in your home, and even measuring the size of our universe. 

You may be thinking…
“What does this have to do with appliance repair?”
It may seem like common knowledge but keeping these principals in the front of your mind when you are troubleshooting some appliance problem is the difference between success and failure.  More often than not, after pulling your hair out for hours trying to solve some obscure appliance problem something like pressure imbalances is what makes that little light bulb come on.

Cohesion

Cohesion is the force that holds together particles of matter in solids and liquids. This cohesive force is stronger in some bodies than in others.

Friction

Friction is the force resisting the relative lateral motion of solid surfaces, fluid layers, or material elements in contact. Its opposite is slipperiness.

Adhesion

Adhesion is the property of a substance which enables it to stick or cling to another substance. Glue, for instance, is held to wood by adhesion.

Inertia

Inertia is the tendency of a body to retain its condition of rest or of motion. The inertia of a hammer prevents it from moving itself. A lathe tends to run after the power is shut off. And clothes tend to want to travel in a strait line away from the center of a spinning washtub; the force of inertia is translated into centrifugal force squeezing water out of the clothing.
