Red and Silver. Thanks so much for all your efforts, the description and the photos. I have other threads on my awning problems but they are very similar to yours but I am glad I did not undertake that motor replacement job. By the way, Dometic quoted me a new motor as part #3310423.137b, Price $416.24 plus $25 shipping. Markarios RV quoted me $399.88 for a replacement motor.
So I decided to call Colaw and the guy says they guarantee it to work and it can be returned within 60 days for a refund if not. Cost was $125. I notified eBay I was returning the $358 control box and then drove to Colaw RV salvage this morning and bought the $125 one which looks like new but is used. While shopping in the store I found yet another one but could not convince the guy to sell it to me cheaper.....lol.
So now I am in the process of wiring the new one into the Winnebago harness (A&E provided the Winnebago 15 pin wiring diagram in the original paperwork with the motorhome. I have read a post for another Forum member that said he put a new control box on his and it is still intermittent on retraction.
Anyway, this darn awning is about to drive me nuts. After I have this control box installed I plan on doing what another recommended - cleaning all the moving parts of the awning roller tube and using silicone or another type lubricant to ease the drag on the motor. Several posts have suggested that the problem may be related to a thermal resistance causing the motor to stop to cool down. Biggest problem is my cool down periods have now extended to hours - overnight on the last trip......lol Wish me luck and I will do the same for you.
