Knowing about the various functioning parts of a dometic refrigerator often helps in two things. When there is a problem, it helps you diagnose what could be the real issue. Secondly, depending on the part which is malfunctioning you could guess the cost of getting the refrigerator repaired. Here are some of the most critical dometic refrigerator parts.
Thermostat
This is the temperature control device and hence, one of the most important parts inside. It has a round knob inside a compartment which can be changed based on your preferences from medium cool to ultra cool and so on. The main function of the thermostat is to cut off the electric supply to the compressor to ensure that the cooling doesn't happen below the point of your preference. This is restored once the temperature starts rising above your selected level. In short, it is a regulator for the environment inside the refrigerator.
Evaporator
It is also known as the freezer or chiller and the sensor of the thermostat is connected to this. The refrigerant enters the evaporator at a very low temperature and pressure. It then sucks the temperature from the item which has to be cooled. The evaporator in a dometic refrigerator is comprised of plates or copper turns or even aluminium tubing. The refrigerant sucks the heat evaporates and is sucked by the compressor.
Compressor
Located at the bottom and back of the refrigerator this component sucks out the refrigerant which absorbs the heat from the items inside the refrigerator. It then discharges the refrigerant which is at high pressure and temperature. This is a continuous cycle where the heat from the items inside the refrigerator, are constantly cooled.
Condenser
This is nicely finned on the back of refrigerator with a lot of surface area so that the refrigerant at high temperature is cooled down in contact with the atmospheric air as quickly as possible.
Refrigerant
This is the another important component, which as discussed flows through all the main parts of the refrigerator and basically acts like a fluid that keeps sucking out the heat depending upon the temperature chosen by the user. The refrigerant is constantly circulated and keeps emitting heat out to the atmosphere.
Capillary
This completes the cycle in a way. This is because the refrigerant enters this expansion mechanism in dometic refrigerators due to which its temperature and pressure drop down drastically and is ready for a new cycle of heat absorption.
Rv Refrigerators My RV refridgerator cut off and the food spoiled for about 10 days. How do I get this odor out?
My RV refrigerator cut off while I was gone for 10 days. Everything spoiled and it had maggots inside. I have cleaned with Mr Clean and soapy water. I also added a box of baking soda to freezer and fridge. The smell is awful. Help!! I cannot take it out. It is built in the cabinets..

OK, you are going to buy an RV and you want the best deal possible. Whether it is a motor home, fifth wheel, or travel trailer, you know MSRP (Manufacturers Suggested Retail Price) is the baseline in establishing price and your goal is to pay 20% to 30% below MSRP.
If you are buying a used RV, you will be using NADA or Blue Book price guides and you should be aware these guides inflate their internet quotes approximately 10%. In addition, you are aware these prices are arbitrary and are to be used only as a guide.
You also know you'll save money by securing your own financing rather than using dealer financing and you know it is in your best interests to be wary of any other "add one's" the dealer may pitch you.
You are now in a position to secure a good deal on that motor home, fifth wheel, or travel trailer except for one tiny matter. You really do not know that much about RV's and even if you do very few recreational vehicle buyers know how to conduct a thorough inspection. In addition, take it from someone who works on them every day. You have no business taking delivery on any RV, new or used, unless you know exactly what you are getting.
As an RV technician, I have a number of guidelines in inspecting an RV and the first one is NEVER ASSUME ANYTHING! I work with many RV'ers six months to a year after they bought their RV's and I cannot believe what they are telling me. They are buying RV's knowing certain things are wrong and they think they will just live with it. It is not long before they tire of that. Let's face it. There are numerous facets involved on these little "houses on wheels" and considering what they cost today it is only prudent consumers do their homework before they take their RV home.
The biggest trap RV buyers fall into when buying a new RV is placing too much emphasis on the manufacturer's warranty. The manufacturers warranty is crucial but too many RV buyers take delivery on motor homes, fifth wheels, and travel trailers with problems that eventually "wear them down" as they continually drag their beloved RV back to the dealership to be repaired.
Anyone visiting an RV dealership or going to an RV sale should be aware of two things the RV Industry has mastered. The first is marketing their product and second is making it look good. Any RV owner knows appearance is only "wall panel and veneer deep" and there is more to inspecting an RV than pushing on cabinets and pounding on walls. If only it was that easy.
RV shoppers quickly discover there is no shortage of used RV's on the market. This should lead us to ask why. Through my experience, I have learned it is a combination of issues with the major one being buying the wrong RV. If RV "type" (motor home, fifth wheel, travel trailer, camper, etc.) is wrong you are doomed. RV size is almost as important as you have to be able to use it in the environment you want to RV in. The smallest RV is larger than most vehicles we are comfortable with so an adjustment is necessary whether driving an RV or towing one. The other issue is RV'ing (and RV maintenance) may not be what the buyer anticipated. Believe it or not RV'ing is not for everyone.
Considering an RV has three complete and individual energy systems (110V, 12Volt DC, and LP gas), chassis and frame considerations, quality check points inside and outside, an appliance system consisting of a refrigerator, water heater, furnace, stove and oven, a fresh water and holding tank systems, and more, analyzing an RV may seem overwhelming to you. The good news is there is a lot of information available to assist anyone willing to learn and I always implore RV'ers to avail themselves of this information and learn as much as possible. Anyone doing this will quickly realize it will be time well spent and more importantly, it can save you money...and lots of it. Happy RV'ing!

12 Volt Refrigerators, An Energy Efficient Storage Solution
If you are on the lookout for an economical and compact refrigeration option, then the 12 volt refrigerator is for you. These refrigerators have an exceptionally low level of energy consumption and a low operating expense. While the smaller versions are ideal for road trips, the larger models are suitable for households that want to save on their energy bills. Shopping online would get you a reliable model to suit your needs.
Customized to Cut Electricity Costs Most 12 volt refrigerators are designed to work on either external batteries (like that of a car) or internal batteries, and are therefore independent of the grid. In many models, the batteries that can be recharged using solar and wind power, and fuel cells. This makes these refrigerators indispensable when you are looking to cut electricity costs, during power outages and in places where electric power is not available.
It must be kept in mind that if a 12v refrigerator is used in a car, it will have to be recharged frequently. This will deplete the life of the car battery. But the battery of a diesel-powered truck, RV or boat battery is much stronger and would be able to support the 12 volt refrigerator well.
Efficient Large Size 12 Volt Refrigerators The large size 12 volt refrigerators come in top loading models as well as upright refrigerators and freezers. Popular for their outstanding performance and durability, these DC-powered solar refrigerators have a range of useful features:
• Automatic operation with low voltage disconnect for battery protection • Thick polyurethane insulation • Rugged scratch resistant galvanized steel exterior • Easy to clean aluminum interior • Lockable lid with Interior light • Corrosion resistant coated steel exterior • Patented low-frost system • Easy to clean interior • Low maintenance • Baskets for food organization
Emergency services like medical, fire and rescue teams use 12V refrigerators to store vaccines and medicines.
Consider Use before Purchase Space, durability and use are factors you need to consider before buying a 12 V refrigerator. If you go in for a thick-walled one, you need to power it for just 5-6 hours to keep your food frozen. A good cooling system is essential for a refrigerator using a solar charger.
