What does 3 blinks mean on an Onan generator?
From the Onan manual: Three blinks indicates a service fault. Press Stop once to cause the two-digit, second-level fault code to blink. ( Pressing Stop again will stop the blinking.)
How do you clear an Onan fault code?
How to Clear a Fault Code on Onan Generator
- Locate the primer button on the generator.
- Hold the primer button down for at least 30 seconds.
- Release the button and start the generator.
- Allow the generator to run for 15 minutes, to ensure that the code has cleared.
Why does my Onan 5500 generator keep shutting off?
If the fuel supply is sufficient but your generator still starts and stops, check the generator’s oil level. Onan RV generators have a “low oil” shutoff that could cause a shutdown. As oil warms it thins out and this may cause it to fall below the proper level.
What does SPN and FMI stand for?
Suspect Parameter Number (SPN) Represents the SPN with error. Every defined SPN can be used in a DTC. Failure Mode Identifier (FMI) Represents the nature and type of error that occurred, e.g., value range violation (high or low), sensor short-circuits, incorrect update rate, calibration error.
What is an SPN code?
The Suspect Parameter Number (SPN) is diagnostic fault code terminology found on some of our equipment using a J1939 CAN data link.
What are FMI on fault codes?
The FMI is used along with the SPN to provide specific information that relates to a diagnostic trouble code (DTC). The FMI may indicate that a problem with an electronic circuit or an electronic component has been detected. The FMI may also indicate that an abnormal operating condition has been detected.
Why is my generator shutting off randomly?
Overloading. In the case of overloading, most generators are programmed to shut down. This feature, home to newer models, saves your appliances from getting stressed when the system is being overloaded. A simple solution to this would be to reduce the load of the generator and to restart it.
