  •  Inspect fuses and breakers in the RV electrical panel.
  •  Verify the thermostat settings.

  •  Remove obstructions from air intake and exhaust vents.
  •  Clean evaporator and condenser coils to enhance heat exchange.

Strange Noises:

  • Inspect fan blades for obstructions.
  •  Tighten loose bolts or screws.
  •  Lubricate the motor and fan bearings if necessary.

Refrigerant Issues:

  • Consult a professional for suspected refrigerant leaks.
  •  Check for ice buildup on evaporator coils.

Thermostat Problems:

  •  Replace thermostat batteries if applicable.

Water Leaks:

Preventive Maintenance Tips:

Regular maintenance is key to avoiding major issues. Consider the following:

  •  Inspect and clean coils at the beginning of each season.
  •  Keep the area around the air conditioner unit free from debris.

When to Seek Professional Help:

While many RV air conditioner issues can be resolved with DIY efforts, some may require professional assistance. If you’re uncertain about the problem or lack the necessary expertise, consult a qualified RV air conditioner technician.


Maintaining a functional RV air conditioner is crucial for a comfortable and enjoyable road trip experience. By understanding the common issues and implementing preventive maintenance measures, you can keep your RV cool and your adventures stress-free.
