My suggestion is to have your service provider on site get in the car with another person jump up and down and see what happens. If you get a governor switch trip with a moderate jump problem should be on them. If you really jump hard and it set it may be as they claim. Also new equipment should record what speed the incident occurred at. What does the records show on the screen? Have them take a picture with their phone. Do they happen in the same place in the hoist way? Same direction of travel? ect ect Good luck!
