Frequently Asked Questions
Q: How do I know if my Dometic air conditioner has this secondary drain pan?
A: The AU9-12 series units include both a primary and secondary drain pan. The secondary pan is the bent component that sits beneath the primary pan. Check your unit's documentation or inspect the underside of your rooftop AC unit to confirm compatibility.
Q: Can I install this myself, or do I need a professional?
A: While experienced RV owners can replace this pan, it requires working on your roof and disconnecting the AC unit. We recommend having a certified RV technician handle the installation to ensure proper sealing and prevent leaks.
Q: What happens if I don't replace a damaged drain pan?
A: A cracked or missing drain pan allows condensation water to pool inside your RV's roof cavity, leading to mold, wood rot, and structural damage. Replacing it promptly protects your RV's interior and resale value.
