Hi, I recently bought an electric Salt & Pepper mill set from Marshals. The brand is Palm restaurant est 1926. Model SL-H02. However, few weeks after one rolled off and fell off the kitchen counter and is no longer working. The bottom light is barely lit and the grinder does not move, even with new batteries. I searched online and was not able to find much information. Is there a way I could replace just this one or repair it. Any help would be greatly appreciated. Thank you in Advance.
