A refrigerator stabilizer is an essential appliance for maintaining a cool temperature inside your refrigerator. This device keeps the temperature consistent by keeping the gas under pressure. This is done through the compressor which pushes hot compressed gas out through a metal coil. When the gas is under pressure, it turns into liquid, and that's what happens when you have a stable voltage. A refrigerator stabilizer is needed only if the refrigerator uses a certain voltage range, and a surge in voltage will not cause it to fail.
