Many generators these days are equipped with a low oil sensor that automatically shuts down the generator when the oil level is low. It is done to protect the engine from harm as a low level of oil when an engine is operating can permanently inflict damage to the generator motor. Sometimes, however, your generator might have issues starting because it has this feature.
If you bought a new generator and it’s not starting, one of the reasons might be the low oil sensor. With new generators, the oil sensor can be frequently stuck to the bottom of the crankcase. As a result, the oil sensor detects no oil and keeps the generator from starting normally even when the fuel level is full.
The solution is simple.
If your generator has a sufficient amount of fuel and you are attempting to run it for the first time, and it fails to start, temporarily disconnect the low oil sensor. It would be best if you located the wire that is connected to the sensor. In different generators, the color of the wire and it’s positioning may vary.
Typically, the wire comes out of a bolt on the crankcase and near the oil fill cap underneath the panel. Find the cable and disconnect the wire from the connector. It is usually the section where two wires connect together, protected by a colored shielding. Typically, the connector has a green shielding made of plastic that looks like a socket.
Once you have disconnected the low oil sensor’s wire from the connector, you will have to wait for a minute and start the generator.
Your generator should start normally. Keep your generator running for a quarter to half an hour. This will allow the oil sensor to get unstuck from the bottom of the generator’s engine.
Next, you have to reconnect the low oil sensor’s wire to the connector.
If your generator does not start after disconnecting the low oil sensor, then the issue might be somewhere else. You should always have a checklist that you follow when your generator is failing to run. This checklist will ensure that you do not overlook the basic problems that generators face from time to time. If you are unsure why your generating fails to start, read “Generator Problems and Troubleshooting Tips.”
Here are some of the essential tips:
- Check the spark plug and the fuel. Make sure you are using the right kind of fuel for your generator.
- Check the air filter.
- Check the fuel filter and fuel line.
- Check the start switch.
- Assess the ignition coil.
- Check the flywheel.
- Look for gas leaks.
Make sure you follow these precautions
Before using the generator, the user must read the user’s manual to reduce injury risks
Do not touch the generator when it’s hot. First, wait for the generator to cool down.
Take note of the moving parts and do not get your finger stuck in the connecting sections.
When working with gasoline-based generators, reduce the risk of explosions and ignitions by putting away cigarettes, flames, and spark inducing equipment. If there’s a risk of electrocution, wear rubber shoes and grounding wires.
