TO DIAGNOSE ALL COOLING UNITS

Models RM3662, RM3663, RM3862, RM3863, RM4872, RM4873
After four hours of operation, feel the back plate of the freezer section. It should be cold to the touch. If cold
to the touch, the unit is working.
If four hours of operation the unit back plate is not cold to the touch, turn the refrigeratorto OFF; wait
after
hours and restart the refrigerator. After four hours of operation the back plate of the freezer section should
be cold to the touch. If it is not cold to the touch after the second four hours of operation, the cooling unit may
be defective.
Verify the AC heating element is good. Then place approximately one gallon of water inside the refrigerator
and place a thermometer in one of the containers of water. Next, supply 115 volts direct to the AC heating
element and operate for at least 12 hours. Check the temperature on the thermometer. It should be 45 degrees
or lower, depending on test conditions.

FOOD STORAGE

It is essential that the shelves are not covered with paper or large storage containers. Always remember to
allow for proper air circulation.
Odorous or highly flavored foods should always be stored in covered dishes, plastic bags, or wrapped in foil
or waxed paper to prevent food odors. Vegetables, lettuce, etc., should be covered. NEVER PUT HOT FOOD
INTO THE REFRIGERATOR.

HIGH HUMIDITY

The condensation may actually run off the frame. As the humidity is reduced, the "sweating" will decrease.

INTERIOR LINER SEAL TO FRAME

Condensation could form on the frame and could promote rapid formation of frost. Apply a small bead of
silicone all the way around the perimeter where the frame meets the interior liner.
Slide the refrigerator out approximately 2-4 inches. Apply a foil-backed adhesive tape to the joint between
outer frame and foil-backed refrigerator insulation.
NOTE: TO FORM A PROPER SEAL, IT IS IMPORTANT NOT TO LEAVE ANY GAPS.
