Frank, I don't work for Losmandy, so you're better off contacting their support directly about any repair/replacement.
Your? safety limits are very conservative, so there will be a very limited area where a flip is even possible. One thing to realize with Gemini L5 is that if you use a Goto to force a flip, the destination coordinates for such a goto must be sufficiently far from the current position, otherwise Gemini might decide that it's easier to reach this destination by staying on the same side of the meridian (as long as the safety limit is not violated.) If you must have such strict safety limits, you may want to try to increase the western goto limit and make it larger. That will increase the area where a goto destination will likely cause a flip. L6 beta is changing some of this logic to improve the reliability of automated meridian flips.
