Cummins Onan A056M474 Reviews & Ratings
Quite Noisy
By Jack B. 
Phoenix, Arizona
Review Posted 05/20/2020 
The generator which was factory installed in my RV is:
Cummins Onan RV QG2500 LP - 2.5 KW RV Generator
Model #: 2.5HGJBB-1121A

I regret buying this generator. Unless you do not care about noise I do not recommend this generator. I acknowledge that I have not had any trouble with it but I have owned it for six years and it has less than 100 hours operating time. It is convenient to have remote, electric start and propane fuel source. However, it is very noisy inside and outside the RV and we avoid using it. The noise specification given in the Operators Manual is 70 dBA at 3 meters (approx 10 feet) at ½ load. I have checked the noise levels several times and have recorded 78.8 dBA at 10 feet at no load. The noise level inside the RV is 54.9 dBA at no load. At full load noise levels increase approximately 2 dBA. Note that the dB scale is logarithmic and a 6 dBA increase results in doubling the noise level. I consider the noise levels produced by this generator to be very loud.

Also, it emits a propane smell when running.

Manufacturer Response
We are sorry for your concerns with the performance of your Onan RVQG 2500. The generators are extensively tested in a sound chamber and real world environments to assure specifications are accurate. Vibration and installation can add to the overall dB being read/heard. Please assure that you have properly installed the generator per installation manual and that your tailpipe is not mounted rigidly. (non rigid hangers). You may also try using an exhaust resonator 0155-2449 to help reduce the noise/tone in certain applications and locations.

There should not be any propane smell while the generator is running, or stationary. The combustion and fuel supply are sealed and this may indicate a leak or a misfiring generator. This is a potentially dangerous situation and needs to be corrected immediately. A list of authorized dealers can be found at locator.cummins.com.
