Yes, I can explain it. No the refrigerator is not a living thing. That's totally irrelevant. You have two forces AND inertia, Newton's first law of motion. Thou are pushing the refrigerator and the equal but opposite force is PRESSURE. The refrigerator is not going to move, because it is at rest and has mass and the force of gravity acting on that mass, until the force of your push is greater than the pressure and friction of the refrigerator.
Forces are vectors. They have DIRECTIONS as well as magnitude. You have 3 forces forces here, the force of your push, the pressure, and the acceleration of gravity at right angles to the other 2 forces.
