On the side of the motor unit you will find the 'down limit' control. Turn this a tad in the opposite direction of the arrow printed on the cover. Some tweaking may be necessary. Keep in mind if you tweak too much the motor will shut off on the thermal overload and you will have to wait until it cools.

I have a proplem with my remotes. None of them will work from >5 feet away from the unit. I have relpaced all of the batteries, reset every remote, and I have replaced the logic board too! I am at my wits end, as the only other thing that I can think of is to replace the entire unit, even though it still works at the wall pad! It is only 5 years old, and I have never had this happen to me before. Any experts out there on this?
