I disengaged the door and opened and closed it manually, the door remains in place wherever I stop it. so it seems the springs are good.
again the door disengaged, I push the button and the chain rotates thru its cycle.
It appears that when I put a load (the door engaged), the problem occurs.
it may be the capacitor. i will check it and replace it at first chance.
again thanks for your help.
Sounds good Rich. With the additional information you provided, it sounds like the start capacitor. Good luck with it.
