Radio Blockage could be the problem caused by the Government, wireless internet companies, transformers, cell towers, radio stations, your doorbell, etc. The FCC is in charge and we have to share the air waves so we will need to change your signal or get you a new motor with security 2.0 witch my motor has! Also check the battery or replace the battery. All so try removing the L.E.D. or Fluorescent light bulbs and try the old incandescent light bulb this sometimes work.
