We have a 2011 Pleasure Way with an Onan Generator (QR2800). It has been exercised regularly but never actually used for more than 30 minutes. Now that we actually need to use it we find that after 30 minutes of running smoothly it surges, sputters, then quits. We have tried fuel cleaner but still the same result. It only has 26 hours on it and received its required 20-hour maintenance, so we really do not want to replace it but we need a reliable generator now. Have we given it some sort of memory by only running it for 30 minutes and not for many hours? —Freda
First, I think you have a QG2800, which stands for Quiet Gas, spec HGJBB.
Second, you won’t have to replace it — hopefully, it just needs service. The best people to provide service on this unit are the Cummins Coach Care Centers or their certified dealers and technicians, but I might be able to help.
The generator switch on the generator itself has a small red light which flashes a code, and there should be a chart for the codes in your genset’s owner’s manual. This code will help determine the issue. According to my contact at Cummins Onan, your problem could be ignition coil related, an intake seal issue, or a sensor problem. A technician will be able to take care of that for you.
