6.6 Fixing a Stuck Lid
NOTICE: DAMAGE HAZARD: If the EPDM rubber
vent lid seal is damaged or torn, contact the Dometic
Customer Support Center.
1. Open the vent lid all the way.
2. Place a liberal amount of denatured or rubbing
alcohol on a clean rag to clean the underside of the
vent lid and the EPDM vent lid rubber seal.
3. If available, apply a water-based (not petroleum-
based) protectant to the inside of the vent lid where
the lid and seal meet. Allow the protectant to dry and
buff the lid with a so cloth to a high sheen.
4. Use a clean rag, paper towel, or foam trim brush to
apply an even coating of 100% silicone to the entire
top surface of the EPDM rubber vent lid seal to
prevent it from sticking to the vent lid.
5. Wash hands thoroughly with soap and water.
