EFFICIENCY OR ENERGY SAVER SWITCHES: If you live in a
warm, humid environment, you may have a problem with condensation forming
on the outside of your refrigerator. This is known as "sweating."
So-called "Energy Saver" switches control small, low-wattage "mullion"
heaters in the side and door panels that prevent the outside of the refrigerator
from getting cool enough for sweating to occur. In the "economy" position,
the heaters are off.
Next, check your condenser.
The locations of the most common types of condensers are shown in Figures 9A & 9B. Any type condenser mount may be used on bottom-freezer, top-freezer or side-by-side units.
FIGURE 9A: Air flows over a back-mounted condenser by convection; the warm air rises and is replaced by cooler air from below. Some of these condensers are covered by a metal plate.
VEGETABLE (CRISPER) or MEAT
COMPARTMENT CONTROLS:
These may be small mullion heaters or they may be separate air doors that control the airflow within these compartments. The idea is to keep the compartment at a different temperature from the rest of the food compartment; a more optimum temperature for the particular food that you're keeping in these compartments.
BUTTER CONDITIONERS: Again, small heaters that keep the butter compartment at a different temperature than the rest of the food compartment.
