It’s important to use the correct type and amount of oil and to replace worn seals as soon as leaks are noticed. Regularly cleaning around the engine and checking for oil during routine maintenance can help you spot leaks early, preventing further complications and ensuring your generator remains in good working condition.

9. Generator Runs Erratically (Surging or Stalling)

When your generator runs erratically, surging, or stalling unexpectedly, it can be a sign of several issues. Often, this behavior is due to problems with the fuel supply, whether it’s contaminated fuel or air bubbles in the fuel line. Another common cause is a dirty or malfunctioning carburetor that doesn’t regulate the fuel input properly. Additionally, a clogged air filter can restrict airflow, causing the engine to receive an improper air-to-fuel ratio. Regular maintenance, such as replacing filters, cleaning the carburetor, and ensuring fresh, clean fuel, can help maintain steady operation and prevent erratic behavior.

10. Low Power Output

Experiencing low power output from your generator is not only inconvenient but also a sign that something is not functioning correctly. This issue could stem from an overloaded generator trying to supply more power than its capacity allows. Alternatively, it might be due to worn or damaged components, such as a faulty alternator or issues within the electrical system itself. Ensuring your generator is not overburdened and conducting regular checks on the electrical components can help restore and maintain optimal power output.

11. Automatic Transfer Switch Failures

The automatic transfer switch (ATS) is crucial for seamlessly switching the power supply from the main grid to the generator during a power outage. Failures in this component can lead to a lack of power when needed most. Common issues with ATS include faulty wiring, a bad connection, or a malfunctioning sensor. Regular testing and maintenance of the ATS can ensure it functions correctly during power failures, providing reliable backup power without interruption.

12. Wet Stacking

Wet stacking is a condition that occurs when unburned fuel accumulates in the exhaust system of a generator, often seen with diesel engines. This can happen when the generator operates below its capacity for prolonged periods, leading to incomplete combustion. Symptoms include a build-up of black, oily residue around the exhaust and reduced engine efficiency. Addressing wet stacking involves running the generator at full load for a certain period to burn off the excess fuel or consulting with a technician to adjust the load settings.

13. Exhaust Issues

Problems with your generator’s exhaust system can lead to inefficient operation and can even be hazardous. Common exhaust issues include blockages, leaks, or damage to the exhaust components. Blockages might be caused by debris or buildup of soot, which can restrict the flow of exhaust gases. Leaks, often found at connections or due to cracks in the exhaust components, can allow dangerous gases to escape into areas where the generator operates. Regular inspections can help identify and correct these problems early, ensuring safe and efficient operation.
