CLASS RACER FORUM - View Single Post - Onan 4000 with shut down but will restart

Mark Ruset · 07-02-2020, 09:47 AM

This past weekend i had my 2018 motor coach Onan 4000 generator intermittently shut down when the A/C was on sometimes it would run for a couple of hours and then shut down, other times it could run for 15 minutes and then shut down. Each and every time the generator would restart with no problems. Prior to the generator shutting down it sounded as if was under a heavy load. If I was quick enough to get into the coach and turn the A/C off I was able to keep the generator running. Any ideas where to begin?
