We have a 2013 Georgetown 378. Have had the same problem. Under the steps in the battery compartment you will find two breakers. Do not go by looks only. Press the red button to trip the breaker, a red leaver will come out, press it back in. Do this for both breakers. Next you should see a small box that contains circuit board with fuses on it. On my unit the 15amp fuse, bottom row, far right controls the slides as well. Test this fuse , don't go by looks alone. This has solved our problems each time... Hope this helps.
