FIXED ???? Roof AC Starts...Stops...Then Run Fine

All RV electronic controlled systems have a 2 minute 45 second time delay on restart of the compressor. This is to allow time for the pressure in the system to equalize to allow easier start up. I would use compressed air to blow out the wall tstat. It may just have accumulated dust and debris on the electronic circuits of the Tstat. I would also check the upper wiring on the AC unit for loose or burnt wire connectors. Doug
