RV Propane Refrigerator Repair Troubleshooting
RV refrigerators typically run on propane or batteries (DC or AC mode). They therefore operate differently from home electric refrigerators and require specific maintenance procedures. Whether you are boondocking or staying at a full-service RV park, following a few tips will help you troubleshoot, repair and maintain your RV propane refrigerator.
Check Propane Control Panel and Settings
Check your RV's control panel to identify the amount of propane in your tank. Refill it if needed. Ensure that the propane level is filled to 80 percent capacity to allow for gas expansion when the ambient temperature rises. Confirm that your propane regulator is switched to the "On" position. Confirm that the mode selector on the refrigerator is set to "Gas." If the propane tank was recently filled, purge the air from the gas line by pressing the power button "Off," then "On" to start a new ignition sequence. Check for propane leaks by applying liquid soap to connectors. Replace connectors if bubbles appear.
Level Your RV
Propane RV refrigerators operate through absorption, where liquid ammonia flows into an evaporator containing hydrogen gas to initiate the cooling process. If an RV is parked on an incline, ammonia can accumulate in the evaporator tubing and cause cooling unit damage. To minimize cooling problems and prevent cooling unit damage, place a small bubble level on a refrigerator shelf or countertop. Adjust the parking angle of your RV until the refrigerator is level.
Ventilate Your Refrigerator
Soot, rust and dirt particles accumulate in the fresh air intake and upper exhaust vents and can affect both the burner and flame sensor. Clean all soot, rust and dirt particles on the inside of the fresh air intake and upper exhaust vents with compressed air and a soft cloth. If necessary, install a fan inside the back of the refrigerator to increase air flow through the condenser fins.
Check the Refrigerator's Temperature
Propane refrigerators can take up to 24 hours to cool, so run your refrigerator overnight before use. Pre-cool items in a home refrigerator if possible. Attach a small kitchen thermometer to the inside of the refrigerator to confirm the temperature stays below 40 degrees Fahrenheit. Check the integrity of the refrigerator door seal by inserting a piece of paper along different areas of the refrigerator door. An intact seal generates resistance when you try to remove the paper; a leaky seal creates no resistance. Replace the seal if necessary.
