So having a Generator can be a savior for you! It is an easy-to-use gadget that provides backup power during a power outage.

From operating in hospitals, construction sites, or software houses to being a portable device for a family to carry along on trips, a generator has proved to be an essential and handy device for everyone.

Have you ever noticed how RV owners get an electrical power supply? RV owners play it smart and get a generator for their RV. RV generators are not limited to standby mode, as they have been used in households.

RV generators are not the safest but also reliable for an 8-24 hours power supply. It helps RV owners to operate their AC, TV, microwave, lighting, and even a slide-out powered by a single generator.

But still, Onan generators are convenient to operate. Recently, users have been reporting a Code 15 issue with the generators. This article will explain the four ways to solve this issue.

Troubleshooting Onan Generator Fault Code 15

1. Check Load On Your Generator

First of all, before following any way to deal with the fault 15 code issue, be evident that each Onan generator has varying features and significance. Therefore, the way to solve the code 15 issue can be quite different for each generator.

But most of them have the same problem, which becomes the reason for the fault 15 code issue.

Onan generators are designed in such a way that they show fault code 15 issues if the AC is unable to provide with 54Hz frequency. Secondly, if the generator is not receiving the required fuel or diesel, these issues indicate the indicator to show a 15 code error.

To get rid of the issue, reduce the load on your generator. Even a person cannot bare a burden more than his patience. Then, how can a human-made device compromise on this?

In the same way as humans, the generator cannot work with a high load, as the frequency will drop. A drop frequency is the main reason for the fault code 15 issue. Read the Onan generator’s manual that comes with it to see how much load your generator can bear.

If your generator is too old and you were not paying attention to its maintenance, then the chances of your generator showing issue are because of overloading.

But for a long-term relationship with your generator, do not ignore its maintenance because once it starts to malfunction, you must replace it.

2. Configure Altitude Settings

If you are spending time in mountains or camping in high-altitude areas in your RV, the generator must have shown an error because of the high altitude. Most Onan generators operate fine at the height of 0-2500 feet and, above that, lose their maximum power.

We have not restricted you from camping in the mountains, but you can go with this generator for as long as 5000 feet above. Because above 5000 feet, the generator won’t work.

Air is crucial for ignition in generators, and the air pressure drops at a high altitude. With this, the generator also becomes dead at a certain height level.

But if you go back to the ground, the fault code 15 issue might not display in your Onan generator’s indicator, and it will start functioning again.

Being at a high altitude level, exposure to the environmental factors on the generator. Electronics inside the radio can malfunction, or environmental factors such as high humidity levels may expose moisture inside the generator unit and result in a short circuit.

This short circuit can cause the generator to show a 15 code error. In this case, try to get it repaired by a generator services expert, and it will start operating again.

But if the faulty component of the generator is fixed and cannot be repaired, you have to buy yourself a brand new Onan generator to enjoy unlimited travel with a power supply.

3. Altitude Dial Not Included

For Onan, their customers come first. Therefore, they have introduced a feature to configure the altitude settings on the generator. With the help of the dial, the user can set the altitude level of the generator at a certain level for certain air pressure.

The generator needs the oil and fuel for the power supply to be selected according to the altitude level. If the dial is not included in the generator, you cannot configure it with its altitude settings or adjustments.

The dial is primarily available on the device. If it’s not included, you cannot configure it, and the fault code 15 issue will not be resolved.

Check Onan’s manual to locate the altitude dial. The manual explains the location of each component and how to operate it.

To have the dial included in the generator, get in touch with the company at least once.

4. Contact the Company

If all of these ways become ineffective, you are left with the only option to get in touch with your device’s support staff. Make sure you give them thorough information about the issue.

Contact Customer Service

Establishing trusting relationships is the core of providing excellent customer service. Be clear about the problem, and support staff will provide an effective solution. If the problem is still not solved, you must immediately check your generator’s warranty!

Each Onan generator comes up with a warranty card along with its manual. Most of them have a warranty of 3 years. But you can find out that on Onan’s website. If you’re unable to, send them a mail.

The team will contact you and inquire you regarding the generator, issue, and its warranty. But before that, ensure the generator radio wasn’t damaged because of your negligence. After successful validation, the company will provide you with a new generator.
