DIAGNOSTIC SERVICE MANUAL

DOMETIC® RM7030/RM7732 Refrigerators

9.4DOOR POSITION

The door position can be checked by observing any misalignment of the door in relation to the frame.

SMOOTH FIT, PROPER SEAL

NOTE: Improper position of the refrigerator door can cause the interior light to stay on when the door is closed.

To adjust either door, loosen the hinge bracket screws, reposition the door then tighten the hinge bracket screws.

To adjust up or down, remove the door and add or remove washers from the lower hinge pin. Reinstall door and check for correct clearances.

9.5AMBIENT TEMPERATURE

This is the temperature surrounding the recreational vehicle, as well as the temperature of air at the back of the refrigerator. As the ambient temperature increases, the air temperature in the area of the cooling unit increases. The RM7030 and RM7732 will maintain approximately 43 degrees food storage temperature at 110 degree ambient temperature. As the ambient temperature increases, it is possible for the interior temperature of the refrigerator to increase. This means proper installation, ventilation and leveling are important for proper operating temperature of the refrigerator.

9.6COOLING UNIT

The cooling unit is a self-contained, hermetically sealed set of coils where the refrigeration process takes place. The chemicals involved in the cooling process include hydrogen, ammonia, water and a rust inhibiting agent. There are no repairs recommended on the cooling unit. If it is defective, replace with a new cooling unit.

To check the cooling unit, first verify the AC heating elements are good (see Sec. 3). Then place approxi- mately one gallon of water inside the refrigerator and

place a thermometer in one of the containers of water. Next, supply 115 volts directly to the AC heating ele- ments and operate for at least 12 hours. Then check the temperature on the thermometer. It should be at 45 degrees or lower depending on test conditions (see Sec. 9.2 and 9.5). If so, the cooling unit is good. If the temperature of the water is above 45 degrees, replace the cooling unit.

9.7FOOD STORAGE

Proper refrigeration requires free air circulation within the food storage compartment. Restricted air circulation within the compartment will cause higher cabinet temperatures. To remedy this situation, simply rear- range your food items. It is also essential that the shelves are not covered with paper or large storage containers. Always remember to allow for proper air circulation.

Odors 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 to retain their crispness.

NEVER PUT HOT FOOD INTO THE REFRIGERATOR.

To reduce frost formation in and on the freezing com- partment, cover stored liquids and moist foods and do not leave the door open longer than necessary.

When the refrigerator is heavily loaded, it takes longer to lower the refrigerator temperature, and longer to make ice. A very heavy load may also cause defrosting.

9.8HIGH HUMIDITY

High humidity may cause a small amount of condensa- tion to form on the frame of the refrigerator. In extreme cases, the condensation may actually run off the frame. As the humidity is reduced, the sweating will decrease. High humidity can also be a factor in rapid formation of frost.

The RM7030 and RM7732 refrigerators have climate controls installed (see Sec. 5.12). Use of the climate control will reduce the formation of condensation on the frame.
