Ammonia is heated to a vapor and then is condensed back into a liquid........the more that can be changed to vapor state the more can be condensed back into a liquid.
The more condensed back into a liquid the more heat can be adsorbed from the refrigerator sections (freezer/food). The more heat absorbed the colder the compartments.
Anything that inhibits/restricts any one of the processes (vapor/liquid/absorption) will cause less cooling.
