You are one fortunate camper if you have a Cummins Onan RV Generator.

These generators are among the finest on the market, and having one makes camping more enjoyable and comfortable no matter where you go.

However, Cummins RV generators, like any other equipment, might develop problems with time.

Fortunately, most Onan RV generator problems can be fixed, and some of them are easy enough for the ordinary handyman to handle.

Here are some pointers for troubleshooting and repairing your Cummins RV generator.

Why not get right in and get that handy device back up and running?

#1. Troubleshooting an Onan RV Generator

Troubleshooting is the first step in repairing Onan RV generators.

Here are a few things you can look into on your own.

Make careful to attempt these things before employing a professional, as you can save a lot of money.

Begin by looking at the fuel gauge.

These generators use a tube to draw gasoline from the RV tank.

Once the tank is below 14 gallons, this tube is often insufficient to draw gasoline through.

If filling your tank doesn’t help, be sure to check the oil level in your generator.

The “low oil” shutdown on Onan generators for RVs might be creating issues.

Replace the spark plugs and filters, run carb cleaner through the system, replace the voltage regulator slip rings, and check the circuit breaker on the rear of the unit, among other things to try.

It’s usually a good idea to look inside the housing for mice and pests, and make sure the ground wire is still securely attached on both ends.

Finally, many recent Onan diesel RV generator models include failure codes shown on the unit’s display.

If this is the case with your model, go to this page or consult your Onan RV generator handbook to figure out what the code on your display means.

#2. Repairing an Onan RV Generator

If none of the above suggestions work and you’re not a natural at DIY tasks, it’s time to hire a professional.

Most small engine repair shops, fortunately, can work on these machines.

As a result, although many customers prefer to attend Cummins-specific repair shops, others believe that lawn mower repair businesses provide more cost-effective fixes.

If you’re short on funds, it’s well worth your time to look into all of your possibilities.

Do you prefer to do the task yourself? YouTube is a great place to learn how to do more complicated repairs.

To get started, watch this video and see where your search leads you.

#3. Parts for Onan RV Generators

Of course, if you want to repair the Onan generator in your RV yourself, you’ll need to locate the necessary components.

PPL Motorhomes has been a terrific resource for us in the past.

Buying used Onan RV generator parts on eBay, on the other hand, is a terrific way to save money, making it the perfect alternative for individuals on a budget.

#4. For Sale is an Onan RV Generator.

Sometimes a generator can’t be mended, or can’t be fixed at all at a fair price.

Purchasing a new generator is the best option in these situations.

Regrettably, replacement generators are too costly.

As a result, we suggest looking for used Onan RV generators for sale if you’re looking for a more economical option.

Used Onan RV generators, like the components indicated above, may be obtained on eBay.

They’re also available in junkyards where RVs have been abandoned.

Craigslist and your local Facebook Marketplace, both of which sometimes carry Onan RV generators for sale, are two more locations to search.

You should be able to discover a reasonable price with a little searching, allowing you to truly enjoy camping once again.
