Onan generators are designed to automatically shut off when they sense low oil pressure. This is a safety feature that prevents damage to the engine. If your Onan generator keeps shutting off, it’s likely due to low oil pressure.
Check the oil level and add more if necessary. If the problem persists, contact a qualified service technician for assistance.
If you own an Onan generator, you may have experienced the frustration of having it shut off unexpectedly. There are a few possible reasons why this might happen, and fortunately, there are some things you can do to fix the problem.
One reason your Onan generator might keep shutting off is that the oil level is too low.
If the oil level gets too low, it can cause the engine to overheat and shut down. To prevent this from happening, make sure to check the oil level regularly and top it off as needed. Another reason your Onan generator might be shutting off is that the air filter is dirty.
A dirty air filter can restrict airflow and cause the engine to overheat. To fix this, simply clean or replace the air filter as needed. Finally, if your Onan generator keeps shutting off, it could be due to a problem with the fuel system.
The fuel system needs to be properly maintained in order for the engine to run smoothly. If there is any dirt or debris in the fuel system, it can clog up the engine and cause it to shut down. Be sure to clean out the fuel system regularly to prevent this from happening.
How Do You Fix a Generator That Keeps Shutting Off?
If you have a generator that keeps shutting off, there are a few things you can do to try and fix the problem. First, check the oil level in the generator and make sure it is full. If it is low, add more oil and see if that fixes the problem.
Next, check the air filter and clean or replace it if it is dirty. Finally, check the spark plugs and wires and replace them if they are worn out. If none of these things fix the problem, you may need to take your generator to a repair shop to have it looked at by a professional.
Why Won’T My Onan Generator Keep Running?
If your Onan generator won’t keep running, there are a few possible reasons. First, check the oil level and make sure it’s full. If it’s low, add more oil and try again.
If that doesn’t work, the problem could be with the fuel system. Make sure there’s fresh fuel in the tank and that the fuel filter isn’t clogged. Also check the carburetor to see if it needs to be cleaned or rebuilt.
If you’re still having trouble, take the generator to a qualified repair shop for further diagnosis.
Why Does My Generator Randomly Shut Off?
If your generator is shutting off randomly, it could be caused by a few different things. First, check to make sure that the fuel tank is full and that there is fresh gasoline in the tank. If the fuel is old or low, this can cause the engine to shut down.
Next, check the oil level and make sure it is full. If the oil level is low, this can also cause the engine to shut down. Finally, check the air filter and spark plugs.
If they are dirty or need to be replaced, this can also cause the engine to shut down.
Why Does My Rv Generator Randomly Shut Off?
If your RV generator randomly shuts off, it could be due to a number of reasons. The most likely culprit is that the engine is overheating. If the engine gets too hot, it will automatically shut down to prevent damage.
Another possibility is that the generator’s oil level is low. When the oil level gets too low, the engine will also shut down to prevent damage. Finally, if the generator’s fuel tank is empty, it will shut off as well.
If your RV generator randomly shuts off, check the engine first to see if it’s overheating. If it is, let it cool down for a bit before restarting it. If the problem persists, check the oil level and make sure it’s topped off.
Also check the fuel tank to make sure there’s gas in it. If all of these things are fine and the generator still won’t start, then you may need to take it to a mechanic for further diagnosis.

Onan Generator Shuts off After 30 Minutes
Onan generators are some of the most popular on the market, but they can be a bit finicky. If your Onan generator shuts off after 30 minutes, there are a few possible causes.
One possibility is that the fuel line is clogged.
This can happen if the generator sits for too long without being used. The fuel line can also become clogged if you use lower-quality fuel than what is recommended by Onan. To clean a clogged fuel line, run some fresh gasoline through it and then blow it out with compressed air.
Another possibility is that the spark plug gap is too wide. This will cause the engine to misfire, and eventually shut down. To fix this, simply adjust the gap on the spark plugs using a feeler gauge.
Finally, it’s possible that the exhaust system is blocked. This can happen if there’s an excessive build-up of carbon deposits in the system. To clean out a blocked exhaust system, remove the spark arrestor screen and use a wire brush to remove any deposits from inside the muffler or exhaust pipe.
Onan 5500 Generator Runs Then Shuts off
If your Onan 5500 generator runs for a few seconds then shuts off, there are a few possible causes. The most common cause is that the fuel supply is not reaching the engine. This could be due to a clogged fuel filter, bad fuel pump, or faulty carburetor.
Another possibility is that the engine is overheating and shutting down to prevent damage. This could be caused by a coolant leak, faulty cooling fan, or restricted air flow. If your generator has an automatic shut-off feature, it may be triggering due to low oil pressure or high exhaust temperature.
You should check all of these potential problems before operating your generator again.
Generator Shuts off After 20 Minutes
If your generator shuts off after 20 minutes, there are a few possible causes. The most common cause is that the engine is overheating. This can be caused by a number of factors, including a dirty or clogged air filter, low oil level, or an issue with the cooling system.
Another possibility is that the fuel supply is insufficient. If you’re using gas, make sure the tank has enough fuel and that the lines are clear. If you’re using propane, check that the tank is full and that there are no leaks in the lines.
Finally, it’s possible that the generator itself is faulty. If you’ve ruled out all other possibilities, contact your generator’s manufacturer for troubleshooting assistance.
Onan Generator Only Runs Holding Start Button
If your Onan generator only runs when holding the start button, there are a few possible causes. First, check the oil level and make sure it’s full. If it is, then the problem may be with the spark plugs.
Try cleaning or replacing them to see if that solves the issue. If not, then it’s likely that there is an issue with the fuel line or filter. Make sure there is no debris in the line and that the filter is clean.
If you’re still having trouble, take it to a qualified technician for further diagnosis and repair.
The Onan generator is a great way to keep your RV or camper powered while out on the road. However, sometimes the Onan generator can shut off unexpectedly. There are a few reasons why this may happen, such as low oil levels, dirty air filters, or a clogged fuel line.
If you troubleshoot the problem and still can’t fix it, then it’s time to call a professional.
