I have over 10 years old T-3 pool cover. It closes with no problem but won't open. All clutches are engaged properly. The rod that's going into the main drum is spinning. The other end of main drum does not. While motor is running to open the cover I was pushing the drum/vinyl by hand to help turning it. This was cover was opened. Seems like whatever is holding the drum to the rod is off or broken.
What can be the problem? Any idea?
