Finding and Replacing the Converter in Your 2018 Airstream Flying Cloud

Airstream trailers are known for their blend of vintage charm and modern convenience. Maintaining their electrical systems, especially the converter, is crucial for a comfortable RV experience. This article focuses on locating and replacing the converter in a 2018 Airstream Flying Cloud, drawing on insights from Airstream owners who have tackled this task.

What is an Airstream Converter and Why Does it Matter?

The converter in your Airstream acts as the heart of your 12-volt electrical system when you're connected to shore power (120V AC). It performs two essential functions:

• Converts AC to DC: It transforms 120V AC power into 12V DC power, which is necessary to run your Airstream's lights, water pump, fans, and other essential functions.
• Charges the Battery: The converter also charges your Airstream's battery, ensuring you have power when you're boondocking or dry camping without a shore power connection.

A faulty converter can lead to a dead battery, flickering lights, and an inability to use your Airstream's 12V appliances, making replacement a priority.

Locating the Converter in Your 2018 Flying Cloud

Finding the converter's location can be tricky, as it varies depending on the Airstream model and year. Here's where fellow Airstream owners have reported finding the converter in similar models:

• Behind the AC/DC Distribution Panel: Several owners suggest checking behind the main circuit breaker panel. You'll likely need to unscrew the panel and carefully slide it out, being mindful of the wiring. The converter might be screwed to the floor in the space behind it.
• Under the Bed: Some Flying Cloud models have the converter located in a compartment under the head of the bed. You'll need to lift the mattress and look for a screw-in compartment.
• Under the Fridge: In some 23FB models, the converter is located under the fridge, within the AC/DC distribution panel.

Step-by-Step Guide to Converter Replacement

Safety First:

• Disconnect from Shore Power: Always disconnect your Airstream from shore power before working on the electrical system.
• Disconnect the Battery: Disconnect the positive and negative terminals of your Airstream battery to prevent any accidental shorts.

Tools You'll Need:

• Screwdrivers (various sizes)
• Wire stripper/cutter
• Wire connectors or butt splices
• Multimeter (optional, for testing voltage)
• New converter (ensure it's compatible with your Airstream model)

Replacement Steps:

1. Locate the Converter: Use the information above to find the converter in your Airstream.
2. Remove the Old Converter:
   • Carefully disconnect the wiring from the old converter. Note the wire colors and their corresponding terminals to ensure correct reconnection later. Taking pictures can be helpful.
   • Unscrew the converter from its mounting location.
3. Install the New Converter:
   • Mount the new converter in the same location as the old one.
   • Connect the wiring to the new converter, matching the wire colors to the terminals as they were on the old converter. Ensure all connections are secure.
4. Reconnect Power:
   • Reconnect the Airstream battery.
   • Reconnect to shore power.
5. Test the System:
   • Check that the converter is charging the battery.
   • Verify that all 12V appliances are working correctly.

Choosing the Right Replacement Converter

Selecting the correct replacement converter is crucial for optimal performance and safety. Consider these factors:

• Amperage: Choose a converter with the same amperage rating as the original. Using a converter with a lower amperage rating may not provide enough power, while a higher rating is generally acceptable but unnecessary.
• Compatibility: Ensure the converter is compatible with your Airstream's battery type (lead-acid, AGM, or lithium). Some newer converters, like the WFCO 8955, feature auto-detect technology for lithium batteries.
• Brand Reputation: Opt for a reputable brand known for quality and reliability, such as WFCO.

When to Call a Professional

While replacing an Airstream converter can be a DIY project, it's essential to recognize when professional help is needed. If you're uncomfortable working with electrical systems, encounter unexpected wiring issues, or are unsure about any step of the process, consult a qualified RV technician.
