either of the above is found, replace the electrode. The spark gap must be set at three sixteenths (3/16") of an inch and tip of electrode above the slots in the burner.

If igniter (see Sec. 5.5A or B) and high voltage cable (see Sec. 5.6A or B) are good and there is no spark at the tip of the electrode, replace the electrode.

5.12 CLIMATE CONTROL HEATER

The climate control is a switch operated DC electric heater. Its primary function is to warm the frame of the refrigerator during high temperature/high humidity conditions. This prevents the formation of condensation on the metal frame.

To check the switch, disconnect the wires and do a continuity check. In the OFF position, there should be no continuity. In the ON position, there should be a continuity reading.

To check the heater itself, do an ohms resistance reading on the heater wire by using a properly cali- brated ohm meter. The proper ohms reading is 34 ohms

±10%. The approximate amp draw is less than .5 (1/2) amp.

NOTE: The climate control will draw DC power continu- ously. It should be turned off when charging source is not available.

SECTION 6

LP GAS REQUIREMENTS

The LP gas pressure to the refrigerator should be 11 inches water column with half of all BTU's of the RV turned on. With all other appliances off, the pressure to the refrigerator should not exceed 12 inches water column. To check the gas pressure when the refrigera- tor is operating, there is a pressure test port on the solenoid.

With a capacity of 7.3 cubic feet, it can hold a substantial amount of food and beverages, making it perfect for extended trips. The RM7732 also boasts an impressive temperature range, allowing it to maintain optimal cooling conditions even in varying outdoor temperatures. Its sleek design includes a reversible door, providing flexibility in installation and use.

On the other hand, the Dometic RM7030 is a double-door refrigerator that combines style with functionality. This model also supports three-way operation: propane, 12V DC, and 110V AC. It offers a slightly smaller capacity than the RM7732 but is still equipped to handle the needs of a small family or group. One of its standout features is its efficient absorption cooling technology, which ensures that the refrigerator operates quietly, making it an excellent choice for nighttime use.

Both models feature an electronic ignition system that simplifies the process of starting the propane function. The intuitive control panel on each unit allows users to easily select the preferred power source and adjust the temperature settings. Energy-efficient LED lighting inside the refrigerators enhances visibility while consuming minimal power.

Dometic has incorporated advanced insulation materials in both the RM7732 and RM7030 to reduce energy consumption, ensuring that food stays cooled even under high ambient temperatures. The sturdy construction is designed to withstand the rigors of outdoor use, and the units are built to last.

In summary, the Dometic RM7732 and RM7030 refrigerators are excellent choices for outdoor enthusiasts seeking reliable, versatile, and energy-efficient cooling solutions. With their range of power options, impressive capacities, and user-friendly features, they are well-equipped to handle the demands of any adventure while keeping your provisions fresh and cool.
