Checking Door Seals
The door gaskets must seal completely around the entire length of the door. This will insure cooling efficiency
and prevent frost formation. Frequent frost formation or reduced cooling can be indications of air leaks.
To check for proper door seal, lay a long narrow strip of paper between the gasket and the refrigerator. Close
the door and withdraw the paper. A frictional drag should be observed. Repeat all around the doors. If the paper
does not have a noticeable drag, the gasket is not sealing. Contact your service agency for corrective procedures.
Defrosting
After a period of operation, frost may accumulate on the freezer plate and the cooling fins, impairing cooling
efficiency. Refrigerator efficiency can be improved by periodically defrosting the refrigerator.
To defrost the refrigerator, set the "Elec-Off- Gas" control knob to "Off". Empty the refrigerator, leaving the drip
tray under the cooling fins and the doors open. To quicken the defrost cycle, fill a pan with hot water and place it
in the freezer. When the frost has melted, empty the drip tray and wipe it with a clean cloth. Replace the drip tray.
Replace all food and restart the refrigerator. Set the "Elec-Off-Gas" control knob to the desired mode of operation.
Set the thermostat to its maximum setting for several hours before returning it to a normal setting.
