OK, tried some lube on the gears and teeth but still motor would not open and close like it should. So I contacted DOMETIC TECH SUPPORT for any suggestions and to my surprise, after explaining to the girl what was happening she had no solution so SHE SAID SHE WILL SEND ME A ENTIRE NEW LIFT MOTOR AND ARM ASSEMBLY,,,,NO CHARGE....... WOW did not expect that. Have always had pretty good experience with Dometic but they went above and beyond for me with with this matter. My hat off to them and thank you for a great experience. They stay on my list for any future purchases.
And also THANK YOU to all who responded with your suggestions and ideas to try to remedy this problem. Have Always got great help from this forum for many many years. THANKS
