Contrary awning motor

Our awning motor works intermittingly. This is an 18' Dometic Weatherpro, guessing it is original equipment, on our 2004 40' MDTS.
We've narrowed the problem to the motor or the control box mounted in a basement compartment. It will usually extend, sometimes retracts or retracts part way, stops. Let it rest, continue to retract and it works fine. Any help out there? Thanks.
PS: to KRAIG: thank you for the tip!! Z

Maybe you have already checked these, but in addition to the motor and/or control box those symptoms can also be caused by needing lubrication on swivel points, poor connections normally at the motor, or main spring tension needing tightening. Through the years, we fixed all of the above and last year changed the motor (expensive but covered by an extended service contract).

I had the same issue on my 2003. My control box was not the Weather Pro, but the technician said both types would have intermittent problems with age, and new ones were often problematic. After changing out the control box and still having a problem, he just swapped my box out for relays and I've had no problems in 4 years.

I've had two power awnings. The biggest problem was low voltage to the motor. They tapped into a 12 volt light socket for power and it wasn't sufficient. I rewired the line and all is well now.

Try running a temporary pair of wires from your battery and see if it cures the problem.
