I have three of the Stren feeders. I had a similar issue before. First, make sure the battery is fully charged. Stren sells a charger that insures a full charge by charging overnight from an electrical outlet. The motors dont spin at full strength if the battery is weak.
Second, Stren has AMAZING customer service. They have even replaced one of mine with a new unit when both upper and lower motors failed. Their warranty is 4 years!
