• Thickness: 3 inches to fit the existing motor clearance
• Shaft hole: D‑shaped 1/2-inch to mate with the factory motor shaft
• Balance and profile designed to minimize vibration when installed properly

How will replacing this fan blade help my RV air conditioner?

Installing a correct replacement restores proper airflow and reduces noise from cracked or imbalanced blades. That improves cooling efficiency and reduces strain on the condenser motor without requiring electrical repairs.

• Replaces broken, warped, or missing blades that cause noise
• Restores even airflow across the condenser for better heat exchange
• Reduces motor load and prevents premature motor wear
• Plug‑and‑play fit avoids modification when matched to listed models

How do I know this is the right replacement part for my unit?

Match the part number, physical dimensions, and shaft shape before ordering. If your existing blade carries part numbers like 3313107.0150000001, 317937.000, or 3107914.008, this JIANBENKJ blade is engineered to be a drop‑in replacement.

• Compare part numbers stamped on your old blade to the listed replacements
• Measure diameter, thickness, and confirm 1/2" D‑shaped shaft hole
• Check the RV model compatibility list against your unit’s model plate
• If uncertain, remove the old blade for a quick physical comparison
