Frost Formation

Furthermore, you can also utilize the unit’s heater set to melt the ice. You may also opt to use the fan setting to melt the ice.

Freon Issues

When your air conditioning unit is surrounded by ice, and you have done the steps in solving frost formation and found no leaks in the unit, you have to replace the freon.

Noisy RV Air Conditioner


Old RV air conditioning units often produce loud noises that can disturb you. As such, constant maintenance and cleaning is necessary. You have to clean the fan blades because these parts make a sound like a broken washing machine. Another step is inspecting your rubber cushions; these parts absorb and catch the vibrations when the unit is running; you have to determine whether your rubber cushions need repair or replacement. You also have to check the duct tubes; oily duct tubes create noise when the air conditioner is running; thus, you have to rinse your duct tubes with water.

You can also lower the noise of the unit by reducing the fan’s speed. You also have to make sure that joints, bolts, and gears are screwed properly.

Reduced Cooling Capacity

When your RV air conditioning unit runs but is not cooling your rig, specks of dust must have infiltrated your air conditioner. When dirt covers your filter, it will result in the unit’s low cooling capacity. With this problem, you may opt to wash your filter with soap and water. Also, check your fins. You have to make sure that your fins are unbent and clean; if there be specks of dirt, you have to wash them away. To maximize the cooling capacity of your RV conditioning unit, make sure to the blower and evaporator.

Water Leakages


When your unit is leaking water, you have to clean and inspect the drain pan and evaporator coil; be sure that your drain pan is not clogged. Also, make sure that the gasket is tightly secured, and the mounting bolts are placed correctly.

Non-functioning Units

When your air conditioning units don’t turn on, check the RV power source and the breaker.

Overusing the Generator


When you use your microwave, air conditioning unit, and television simultaneously, there is a tendency that you will overuse your generator. This instance can make your generator broken; thus, you have to get a new one and monitor your wattage.

Overheating Air Conditioning Units

When your unit overheats, make sure to inspect the condenser coil. You have to clean the condenser coil since specks of dirt can cause the unit to be hot; thus, it will prevent the air conditioning unit from working efficiently.

Release of Warm or Hot Air


When your unit releases warm or hot air instead of cold air, you have to inspect and examine your motor voltage.

Foul Smell by the Air Conditioner

When a foul smell troubles you and disrupts your adventure, you have to inspect and clean the radiator. You should also replace the filters of your unit. With these steps, you can, more or less, get rid of the foul odor.
