How to ID Roof AC Model on 2004 Fleetwood Expedition

Identifying Your Roof AC When the Sticker is Gone

What if identifying your mystery roof AC unit doesn't require crawling around your RV with a magnifying glass hunting for that weathered sticker? Don't worry though, there are several reliable ways to determine your exact AC model even without the original label.

Start with Physical Measurements and Visual Clues

If you can safely access the roof (use proper fall protection, ensure roof can support your weight, and avoid wet/icy conditions), measuring your AC unit is the most reliable first step. Standard RV roof ACs come in specific sizes, and the dimensions will immediately narrow down your options.

Measure the roof opening dimensions: Most units are either 14x14 inches or 16x16 inches for the roof cutout (verify measurements for your specific unit). The actual unit housing will be larger. Take measurements of both the opening and the overall unit dimensions.

Look for distinctive visual features: Even without the sticker, different manufacturers have recognizable design elements. Dometic units often have a distinctive shroud shape and vent pattern, while Coleman units have their own characteristic styling. The control knob configuration and color can also be identifying factors.

Check Your Interior Control Panel

The indoor control panel or thermostat often provides crucial identification clues. If your AC has a digital display, the startup screen sometimes shows the model information. Manual controls may have part numbers printed on them that can lead you to the main unit specifications.

Additionally, removing the interior ceiling assembly (usually held by screws around the perimeter) may reveal model information printed on internal components or wiring labels that weren't exposed to weather.

Research Fleetwood's Standard Equipment for 2004

RV manufacturers typically use specific HVAC suppliers during certain production periods. For 2004 Fleetwood Expeditions, you'll want to check what brands were commonly installed. Dometic and Coleman were among the common suppliers during this era, but verify with Fleetwood records.

Contact Fleetwood customer service with your VIN number - they may have records of the original equipment specifications. Many owners report success with this approach, even for older units.

Use Amperage and BTU Requirements

If you can access your RV's electrical panel (ensure power is off and use proper electrical safety precautions), look for the AC circuit breaker. The amperage rating can help identify the unit size. Most roof ACs fall into these categories:

• 13,500 BTU units typically draw 11-12 amps (verify for your specific unit)
• 15,000 BTU units typically draw 13-14 amps (verify for your specific unit)
• Heat pump models may have different electrical requirements

Cross-reference this information with the physical dimensions you measured earlier.

When You Need Professional Help

If these methods don't provide clear identification, consider having an RV technician examine the unit. They can often identify models quickly based on internal components, mounting systems, and refrigerant connections that aren't immediately obvious to owners.

An experienced tech can also determine if you're dealing with a heat pump model versus cooling-only, which affects part compatibility and replacement options. For comprehensive electrical troubleshooting, our electrical systems guide covers the diagnostic basics.

Planning Your Next Steps

Once you've identified the model, you'll have several options depending on the unit's condition. If it's a simple repair, having the correct model number ensures you get compatible parts. If replacement is necessary, knowing your roof opening dimensions and electrical requirements will help you choose an appropriate modern equivalent.

Keep in mind that 2004-era AC units may use R-22 refrigerant, which affects service options and costs. Modern units use R-410A refrigerant and often provide better efficiency, so replacement might be more cost-effective than major repairs on an older unit.
