How to Troubleshoot RV Generators

  1. 1 Make sure you have enough fuel in your fuel tank.
    • Most RV generators stop running if the fuel tank is not at least half full. This is to prevent the RV from using its’ entire fuel supply.
    • Check the fuel gauge to make sure that the tank is at least half full.
    • Add fuel if there is not enough.
  2. Inspect the exhaust system.

    • This is under the RV.
    • To make sure that you inspect all components of the exhaust system, consult your RV’s manual for a detailed description of where to look.
    • Check for surface damage to the exhaust system.
    • Check for oil and fuel leaks.
    • Gently pull on the exhaust system to confirm that it is securely attached to the RV.
    • If there is any damage to the exhaust system, have a RV mechanic repair it.
  3. Inspect and clean the wire lines.

    • Consult your RV’s manual for the locations of all wire lines.
    • Check them for corrosion, rust, and other debris.
    • Use an air pump to dislodge any materials that are stuck between the wires. This can be purchased at a camping supply store.
  4. Check the oil level in the RV.

    • If the oil pressure drops below a certain point, some generators have a sensor that will turn the generator off.
    • Consult your RV’s manual for how to check the oil.
    • If the oil level is below the recommended amount for your RV, add enough oil to meet the recommended amount.
    • Press the start button so that the generator will not bypass the oil pressure cut off circuit. Consult your RV’s manual for the location of this button.
    • Verify that the sensor wire has not been damaged. Consult your RV’s manual for its’ location.
    • Have a RV mechanic repair any damage to the sensor wire, if necessary.
  5. Change the oil and filter (optional).

    • Check your RV’s manual for the recommended service schedule for oil and filter changes. If it is past due, this should be completed.
    • Change the oil and filters if you know how to do so or have a RV mechanic do it.
    • Run the generator for 10 seconds and turn it off.
    • Inspect the generator for oil leaks or wipe it with a white cloth.
    • If oil is leaking from the generator, have it repaired.
  6. Test your RV generator.

    • Turn the generator on and observe its’ performance.
    • After completing these steps, the RV generator should function properly. If it still does not work properly, have a RV mechanic evaluate it.
