absorption refrigerator level.)

• 

Heavy frost build-up on evaporator fins? To prevent frost buildup, do not leave the unit’s 

door open longer than necessary. 

• Overpacked refrigerator? The unit will have to work harder if refrigerator is stuffed, and re-

sults in higher cabinet temperatures. Arrange food in the unit to allow for free air circulation.

Is the plug firmly connected to the receptacle? Is the receptacle energized? Check the

• Air in the gas line? After changing a gas bottle or after a long shutoff period, the gas line is 

likely to be filled with air. You may have to repeat the lighting procedure (45 seconds) by 

turning the refrigerator off and on several times in order to purge the air out of the gas lines.
