2018 Force HD 37TS. Bedroom slide closed as normal this morning. Got to our new site and went to put out slide and nothing. No sound no movement in or out. Accu slide wiring diagrams show a controller and 30 amp fuse. Any idea where these components are ? Checked fuses in panel for slides and all good. cables are all tight and there has been no unusual sounds when operating it in the past. Any help would be appreciated.
