Hello, Trish. Your analysis is dead on: your worm gear has stripped out. This is a common failure point on older operators. The good news is that we sell the operators that will replace this. See our 39-031 and 39-032. I am fairly confident that these are what you want but review our specs and see what you think. Dimensions for 39-032
