How to Hook Up Manifold Gauges to a Refrigerator

Hooking up manifold gauges to a refrigerator helps determine if it needs more refrigerant. This is necessary when the homeowner feels that the unit is not cooling properly. The correct temperature inside a refrigerator ensures that food and beverages stay safe for consumption. Hooking up the gauges prevents having to call a serviceman to determine the cause of the problem.
