Experiencing issues where your RV fridge is not working but the freezer is? This problem might be related to the power supply. Ensuring that your fridge receives consistent power is crucial for its proper functioning. In this section, we will focus on checking the power supply to diagnose the issue. Let’s dive into the steps you need to take.
Inspecting Electrical Connections
Start by inspecting all electrical connections. Loose or corroded wires can disrupt power flow. Ensure all connections are secure. Look for any signs of wear or damage. Replace any faulty wires immediately. This simple step can often resolve the issue.
Testing Voltage Levels
Next, test the voltage levels. Use a multimeter to check if the fridge is getting the correct voltage. The fridge should receive around 120 volts AC. If the voltage is too low or too high, it can affect performance. Adjust the power supply accordingly. Proper voltage ensures the fridge and freezer work efficiently.
Cooling Unit Functionality
Understanding the cooling unit functionality of your RV fridge can help diagnose issues. The cooling unit is the heart of the refrigerator. It plays a critical role in maintaining the proper temperature. The fridge and freezer sections rely on this unit to function correctly.
Ammonia Absorption Process
The RV fridge uses an ammonia absorption process. This process involves a mixture of ammonia, water, and hydrogen gas. The mixture moves through a series of tubes. When heated, the ammonia evaporates and creates a cooling effect. This cooling effect helps keep the fridge and freezer at the desired temperatures.
The evaporated ammonia absorbs heat from the fridge compartment. It then moves to the condenser, where it cools down. The cooled ammonia returns to its liquid state. This cycle repeats, ensuring the fridge and freezer stay cool.
Signs Of Cooling Unit Failure
Several signs indicate a cooling unit failure. One common sign is the fridge not staying cold. The freezer might still work, but the fridge section remains warm. Another sign is a strong ammonia smell. This smell indicates a leak in the cooling unit. A leaking unit will not function correctly.
Visible corrosion on the cooling unit is another sign. Corrosion can affect the unit’s efficiency. If you notice these signs, the cooling unit might need repair or replacement.
Regular maintenance can prevent these issues. Check the cooling unit for leaks and corrosion. Ensure the ventilation around the fridge is adequate. Proper care can extend the life of your RV fridge’s cooling unit.

Thermistor Problems
Experiencing issues with your RV fridge can be frustrating. One common problem is the fridge not cooling while the freezer works fine. This often points to thermistor problems. The thermistor is a sensor that monitors the temperature inside your fridge. If it malfunctions, it can cause cooling issues.
Detecting Faulty Thermistor
First, you need to check if the thermistor is faulty. Use a multimeter to test the thermistor’s resistance. The readings should change with temperature. If there is no change, the thermistor might be faulty. Another sign is if the fridge cools too much or not enough.
Another method is to check the fridge’s control board. Some RV fridges have a diagnostic mode. This mode can show error codes related to the thermistor. Check the user manual for instructions on entering this mode.
Replacing Thermistor
If the thermistor is faulty, replacing it is a must. Start by unplugging your fridge. Remove any food and shelves to access the thermistor. It is usually located near the cooling fins.
Carefully disconnect the thermistor from its wiring. Install the new thermistor by connecting it to the same wiring. Make sure it is secured in place. Plug the fridge back in and test if it cools properly. If the fridge works fine, the thermistor was the problem.
Ventilation And Airflow
Proper ventilation and airflow are crucial for an RV fridge’s performance. Poor airflow often causes the fridge to stop cooling while the freezer works. Ensuring good ventilation helps maintain consistent temperatures.
Clearing Obstructions
Check for any obstructions around the fridge vents. Remove any debris or items blocking the vents. Blockages prevent proper airflow, which can affect the fridge’s cooling ability. Keep the area around the vents clear.
Inspect the back of the fridge where the coils are located. Dust and dirt can accumulate here. Clean the coils regularly to keep airflow unimpeded. Use a soft brush or vacuum for cleaning.
Improving Air Circulation
Ensure there is enough space around the fridge for air to circulate. Crowded spaces restrict airflow. Leave at least a few inches of space on each side of the fridge.
Consider installing a small fan near the fridge vents. This helps improve air circulation. It can be especially useful in hot weather. A fan can push the hot air out and pull cooler air in.
Check the fridge’s internal fans if it has them. These fans should work properly. If they are not running, they may need repair or replacement. Proper internal airflow is essential for maintaining fridge temperature.
