Frequently Asked Questions

How do I know if my plenum needs replacement?

Common signs include reduced airflow from vents, warm spots in your RV despite the AC running, visible cracks or damage to the plenum housing, whistling or air leak sounds near the AC unit, or condensation around the plenum area. If you notice any of these symptoms, inspect your plenum for damage.

Can I install this plenum myself?

Yes, if you're comfortable working on your RV's roof and have basic hand tools. Installation typically involves removing the AC shroud, disconnecting the old plenum, cleaning the mounting surface, and securing the new plenum with the included hardware. Always ensure proper sealing to prevent air leaks. If you're unsure, consult a certified RV technician.

Will this plenum work with my ducted air system?

This plenum is designed for specific Dometic ducted air conditioning systems. Verify your current AC unit model number and compare it with your existing plenum part number to ensure compatibility. The plenum must match both your AC unit's output configuration and your RV's duct system layout.

What's included with this plenum assembly?

The assembly includes the complete plenum housing, mounting hardware, and gaskets required for installation. You may need to reuse some components from your existing installation depending on your specific AC unit configuration.
