Resetting Generac Generator
Resetting your Generac generator is a critical step in troubleshooting common issues you may encounter. Here’s how to address specific error codes that can arise, providing you with a starting point to get your generator back in working condition.
Overcrank, Code 1100
Encountering an Overcrank, Code 1100, on your Generac generator signifies that the engine has attempted to start but failed. To troubleshoot, first, reset the controller. Next, ensure that the gas supply to the generator is turned on. If the engine still does not start, it may be time to seek assistance from an authorized service dealer.

Overspeed, Code 1200/1205
An Overspeed error, shown as Code 1200 or 1205, indicates that the engine’s RPMs are too high. This could be due to a malfunction such as defective ignition coils. To resolve this, resetting the controller is the first step, but if the issue persists, professional servicing by an authorized dealer will be necessary. For a more comprehensive look at this error, check out our generac generator error codes page.
Low Oil Pressure, Code 1300
If you see the Low Oil Pressure, Code 1300, on your generator’s display, check the oil level immediately, adding more if it’s low, as per the instructions in the owner’s manual. Should the oil level be adequate and the error code remains, it’s advisable to make a service call to address the issue. For additional insights on this error, refer to our generac generator troubleshooting guide.
RPM Sense Loss, Code 1501/1505/1511/1515
RPM Sense Loss, indicated by Codes 1501, 1505, 1511, or 1515, occurs when the generator fails to start in AUTO mode. Clear the alarm, then try restarting the generator, ensuring to remove any excessive loads. It’s also essential to check the status of your battery. For a detailed walkthrough on this procedure, visit generac generator troubleshooting battery. If these steps do not resolve the issue, reaching out to an authorized service dealer is the recommended course of action.
Underspeed, Code 1600
The Underspeed error, Code 1600, suggests that the correct RPM is not being detected by the controller. In the event of this error, after attempting a reset, the next step should be to contact an authorized service dealer for expert assistance. For further guidance, the generac generator reset instructions can provide additional support.
In all cases, if your Generac generator continues to display error codes after you’ve attempted a reset, or if it keeps tripping or won’t reset, reaching out for professional help is crucial. Remember, regular maintenance and understanding how to reset your Generac generator can prevent many of these issues from occurring in the first place.
Preventative Maintenance Steps
Preventative maintenance is key to ensuring the longevity and reliability of your Generac generator. By following a few critical steps, you can avoid common issues and maintain optimal performance.
Initial Installation Requirements
When you first install your Generac generator, specific initial steps must be taken to ensure it runs correctly. After the first 25 hours of runtime, an oil change and valve inspection or adjustment are required. However, note that 14 and 18kW units with 816cc engines have hydraulic lifters and do not need a valve adjustment, only an oil change. Always refer to your owner’s manual for exact maintenance requirements for your specific model before conducting any maintenance.
Routine Maintenance Schedule
To keep your Generac generator in peak condition, adhere to the following routine maintenance schedule:
Maintenance Task | Interval |
---|---|
Check engine oil level | Before each use / Daily if running continuously |
Clear dirt and debris | Before each use / Daily if running continuously |
Check fuel and oil lines | Before each use / Daily if running continuously |
Oil and oil filter change | Every 200 hours or every 2 years (whichever comes first) |
Check spark plug and valve clearance | Every 400 hours or every 4 years (whichever comes first) |
Replace air filter | Every 400 hours or every 4 years (whichever comes first) |
Battery condition and charge level | Annually |
