RV Refrigerator Not Cooling? Climate Impacts, Lifespan, What to Do
Owning a recreational vehicle (RV) allows you the freedom to hit the open road and explore new places whenever the mood strikes. Perhaps that’s why over 40 million people own RVs in the United States.
But perhaps what makes RVing so unique and enjoyable is that it offers many of the convenient features you’d find in a home. Things such as a comfortable bed, a cooking stove, and a refrigerator to keep your food fresh.
However, much like a home refrigerator, your RV refrigerator can sometimes experience problems – and when it does, it can put a damper on your RV adventures.
So, in this article, we’ll discuss some of the most common reasons why your RV refrigerator isn’t cooling properly and how to fix them. Let’s get started!
How Long Do RV Refrigerators Last?
RV refrigerator lifespan varies significantly by type, impacting maintenance needs for RV owners. Absorption refrigerators, commonly found in older RVs, have an average lifespan of 10-15 years but often require more frequent repairs due to their complex cooling systems. Compressor-based fridges, typically in newer models, can last up to 20 years with fewer issues, especially in Florida’s hot climate.
Seasonal Impacts on RV Refrigerator Failures
Cooling issues with RV refrigerators spike during the summer months, especially in Florida, largely due to higher ambient temperatures and increased usage. RV owners are advised to pay close attention to their cooling systems during peak heat to avoid mid-journey breakdowns.
Mark Polk from RV Education 101 suggests, “The outside temperature directly affects the operation and efficiency of your RV refrigerator, too. When it’s hot outside, try parking your RV with the side the refrigerator is on in the shade.“
On the flip side, winter conditions can impact RV refrigerator performance differently. Absorption refrigerators, which rely on heat exchange, often struggle in colder weather as low ambient temperatures can disrupt the cooling cycle, leading to inefficiencies. According to Norcold’s owner manual, “A gas absorption refrigerator is not designed to operate in freezing temperatures. If the refrigerator is not equipped for low-temperature operation, and if the cooling system of the refrigerator is exposed to temperatures of 32° F. or lower for an extended period of time, the refrigerator operation may be disrupted. The refrigerator operation will resume when the cooling system of the refrigerator warms sufficiently.”
In contrast, compressor-based fridges maintain consistent performance, as they function independently of external temperatures.
Both types may still require winterization steps, such as adjusting temperature settings and ensuring proper ventilation, to maintain optimal cooling efficiency during colder months. Understanding these differences helps RV owners prepare their fridges for winter use. Regular seasonal maintenance can also help mitigate these risks and ensure reliable performance during Florida experiences sweltering summers and mild winters.
How Cold Does an RV Refrigerator Need to Be?
Before getting into the reasons your RV refrigerator isn’t cooling as it should, it’s important to understand what a proper level of cooling is.
The U.S. Department of Agriculture (USDA) recommends that your refrigerator temperature be set to 40°F or below for food safety. The sweet spot, however, is around 34°F to 35°F. RV freezers should be set to 0°F or below.
Food stored in temperatures higher than the recommended levels can quickly spoil and become dangerous to eat. So, if your RV refrigerator isn’t cooling properly, be sure to address the issue as soon as possible.
5 Common Reasons Why Your RV Refrigerator Isn’t Cooling
Now, let’s look at the top causes of RV refrigerators not cooling as well as they should. The most common reasons include:
1. Power Supply Issues
One of the primary reasons why your RV refrigerator may not be cooling properly is due to insufficient power supply. The power supply to your RV refrigerator can be affected by a variety of factors, including low voltage, poor wiring, and faulty components.
What to do:
To ensure that your RV fridge is getting an adequate amount of power:
- Inspect Fuses and Circuit Breakers
Check the fuses and circuit breakers related to the RV refrigerator. A blown fuse or a tripped circuit can disrupt the power supply to the fridge, causing inadequate cooling. If you discover a blown fuse or tripped breaker, replace the fuses or reset the circuit breaker as needed.
- Avoid Overloading One Circuit
Make sure that you are not overloading one circuit with too many appliances. Every circuit has a specific amperage rating, which represents the maximum amount of current that it can carry. Exceeding the amperage rating can cause your RV refrigerator to not cool properly or even shut off completely.
- Check the Connection
Lastly, check that the connection between the power source and your RV refrigerator is secure. A loose or disconnected wire can prevent the necessary power from reaching the fridge. So, make sure that all connections are tight and secure.
2. Insufficient Ventilation
RV refrigerators require proper ventilation to function optimally. If there is limited airflow around the fridge, it cannot efficiently dissipate heat, resulting in ineffective cooling.
What to do:
To ensure proper ventilation, you must inspect the area surrounding your RV refrigerator. Make sure that the vents are not blocked or restricted in any way. Additionally, check that there is no furniture blocking the airflow around the fridge.
If you discover a ventilation issue, take immediate steps to correct it. For instance, you might need to modify the surrounding area slightly, such as rearranging furniture. Another potential solution is to install an RV vent fan near the refrigerator for supplemental air circulation. This will help the fridge to dissipate heat more efficiently, resulting in better cooling performance.
3. Faulty Thermostat
The thermostat is one of the most important components of an RV refrigerator. It is responsible for sensing and regulating the temperature inside the fridge. As such, if it malfunctions, your RV refrigerator will not cool properly.
What to do:
To check if the thermostat is working correctly, try adjusting it and observe the changes in temperature. If the temperature does not change when you adjust the thermostat, that’s a sign that it is malfunctioning.
In this case, you need to replace the faulty thermostat. This may require professional assistance since it is a delicate and complicated process. So, if you are not comfortable carrying out this work yourself, contact an experienced technician for help. They will be able to diagnose the issue and provide the necessary repairs.
4. Cooling System Problems
Another common reason for RV refrigerator cooling issues is problems within the cooling system itself. The cooling system in an RV refrigerator is a complex mechanism that includes components like the condenser, evaporator, and compressor.
What to do:
If one or more components are malfunctioning, it can result in poor cooling performance. The best way to diagnose and fix this issue is by having a professional inspect the fridge’s cooling system. They will be able to identify any problems and provide the necessary repairs.
In some cases, certain parts of the cooling system may need to be replaced – which a professional RV service technician can do.
5. Refrigerant Leak
A refrigerant leak can significantly impact the cooling performance of your RV refrigerator.
Refrigerant is a crucial component that absorbs heat inside the fridge and releases it outside, allowing for the cooling process to occur. When there’s a leak in the refrigerant system, it disrupts this cycle and leads to inadequate cooling.
What to do:
To detect a refrigerant leak, you’ll need to have the RV refrigerator serviced by a professional technician. They will use special equipment and techniques to determine if there is indeed a leak and can repair it accordingly. Refrigerant leaks should be fixed as soon as possible since they can cause further damage to the fridge’s components if left unchecked.
How Often Should You Service Your RV Refrigerator?
For optimal performance, it’s recommended to have your RV refrigerator serviced once every RV season. This will help ensure that any potential issues are detected and addressed in a timely manner, helping you avoid costly repairs down the line.
If you use your RV on a frequent basis, or if you’ve noticed any issues with the fridge’s cooling performance, you may need to have it serviced more often. A professional technician can assess the condition of your fridge and advise you on the best course of action.
In addition to servicing your RV refrigerator, it’s important to maintain it properly. Cleaning the interior on a regular basis and ensuring that the vents are clear of any debris can help keep it running smoothly. Additionally, checking the seal around the door every now and then will help prevent cold air from leaking out. Taking these steps can extend the life of your RV refrigerator significantly.
