When operating your Onan generator, you may sometimes notice a series of three blinks, followed by six blinks on the indicator light.
This pattern is not a random occurrence, but a coded signal representing a specific issue with your generator. Understanding these signals is crucial for maintaining your generator’s performance and longevity.
This guide aims to demystify the “3 blinks then 6 blinks” code, providing you with potential issues it could represent and the fix to get your Onan generator back in proper working order.
Onan Generator 3 Blinks Then 6 Blinks
1 . Faulty Ignition Switch
A Faulty Ignition Switch can be the culprit behind the 3 blinks, then 6 blinks signal on your Onan generator.
Over time, wear and tear or dirt accumulation can impair the switch, disrupting the generator’s starting mechanism and causing the blinking error code.
Solution
The solution to a Faulty Ignition Switch is either cleaning or replacing the switch.
To clean, turn off the generator, gently remove the switch with a suitable tool, and use a switch cleaner to eliminate any dust or grime.
If cleaning does not solve the issue, you may need to replace the switch.
2 . Inadequate Fuel Supply
An Inadequate Fuel Supply could trigger the 3 blinks, then 6 blinks error code. This issue commonly arises due to blocked fuel lines or an empty fuel tank which prevents the generator from receiving the necessary amount of fuel.
Substandard fuel quality or incorrect fuel type can also contribute to this problem.
Solution
For the solution, start by checking the fuel levels in your generator.
If the tank is empty or near empty, refill it with the appropriate fuel type. In cases of blocked fuel lines, unclogging them might solve the issue.
A fuel conditioner can be used to improve the quality of fuel and prevent future blockages. If the problem persists, consider seeking professional advice.
3 . Blocked Air Filter
A Blocked Air Filter can often be the source of the 3 blinks, then 6 blinks error code on your Onan generator.
The air filter, a crucial element for the generator’s function, ensures a clean air supply to the engine.
However, prolonged usage without proper maintenance can lead to dust and debris accumulation in the filter, thereby obstructing airflow and jeopardizing the generator’s performance.
Solution
The solution to a Blocked Air Filter involves inspection and necessary cleaning or replacement. To inspect the filter, switch off the generator and carefully remove the air filter.
If the filter is noticeably dirty or clogged, it needs to be cleaned or replaced. Cleaning can be done using a mild detergent error occurred during generation.
4 . Damaged Control Board
A Damaged Control Board can often instigate the 3 blinks, then 6 blinks error code on your Onan generator.
The control board is the brain of the generator, responsible for managing and monitoring all major functions. If it malfunctions due to any reason, it will send out the 3 blinks, then 6 blinks error signal.
Solution
The solution is either cleaning or replacing the control board. To clean, turn off the generator and carefully remove the control board from its casing using a suitable tool. Then use an electronic cleaner to eliminate dust and dirt before placing it back in position.
If cleaning does not solve the issue, consider replacing the board with a compatible one. It is important to note that only trained personnel should conduct any kinds of control board repairs or replacements.
Generators are complex machines and require specialized expertise for troubleshooting and maintenance. Therefore, it is advised to contact a professional Onan generator technician in case of any technical issues.
5 Malfunctioning Voltage Regulator
A Malfunctioning Voltage Regulator can also trigger the 3 blinks, then 6 blinks error code on your Onan generator. The voltage regulator plays a pivotal role in maintaining the generator’s electrical output at a steady level.
It ensures that the generator produces the right amount of power, preventing any damage to the engine from voltage fluctuations.
However, if the regulator becomes defective or starts malfunctioning, it may fail to control voltage levels properly, leading to error signals.
Solution
The solution is to either clean or replace the regulator. To clean, turn off the generator and carefully remove the voltage regulator from its casing. Then use an electronic cleaner or compressed air to clear out any dust or debris present in the unit before placing it back.
If cleaning does not solve the issue, consider replacing it with one compatible with your Onan generator model. Make sure to only purchase genuine Onan parts for the best results.
Conclusion
In conclusion, the Onan generator’s “3 blinks then 6 blinks” signal could indicate several potential issues.
These may range from a faulty ignition switch, inadequate fuel supply, blocked air filter, or damaged control board, to a malfunctioning voltage regulator.
Each of these issues could result in the generator being unable to function optimally. Understanding what each signal means and addressing each issue promptly will ensure the generator’s reliability and longevity.
Always remember, regular maintenance is key to prevent major issues, and it’s always advisable to consult with a professional if the issue persists or you’re unsure of how to fix it.
