In this article we share the true secrets that separate a good cooling unit install from a bad one. This includes steps with precise methodology, environmental awareness and safety precautions.
rv cooling units Roof-mounted air conditioning units in most RVs are ducted and offer a number of different ducting options that distribute the cold air throughout the living area. However, many campers use a non-ducted RV air conditioner (like the Dometic RTX2000) that is plugged in and powered by 110V and is used as an “extended refrigerator” to keep food cold during extended camping stays. This type of refrigerator also has a heating element that provides warm water for dishes and drinks.
There are several companies that sell remanufactured Nordic cooling units. These are a more economical choice than replacing the entire absorption refrigerator. However, it is important to note that not all remanufactured coolers are created equal. It’s not uncommon for a company to cut corners and put together a cooling unit with inferior parts.
Before attempting to remove the cooling unit, it’s recommended that you shut off power and disconnect the 120VAC from the refrigerator and the 12VDC from the battery bank. It’s important to take care when prying on the unit as a little force can cause it to rupture.
Some manufacturers have instructions that recommend using thermal mastic around the sealing joint between the evaporator foam pack and the pocket. It’s important to scrape off all of the Thermo-Mastic and then clean the inside of the pocket. A yellowish-type stain in the absorber vessel usually indicates a refrigerant leak, and this is a sign that it’s time to replace the refrigerator’s cooling unit.
