6 Reasons Your Generator Keeps Shutting Off and Ways to Respond

6 Reasons Your Generator Keeps Shutting Off and Ways to Respond

Generators keep homes and businesses operational even in a power outage, giving you greater peace of mind when storms hit. If your generator keeps shutting off, this is a sign of an issue with your system. Fortunately, we have created an outline to help you become familiar with common generator problems and ways to maximize the lifespan of your system for long-term cost savings.

Why Does My Generator Keep Shutting Off?

Wondering why your generator keeps shutting off unexpectedly? Weโ€™ve identified some common culprits, which are outlined below:

1. Electrical Overload

Your backup generator may frequently shut off due to electrical overload, a common issue in many homes. Preventing overload is crucial for smooth operation.

Ensure the total load of all connected appliances doesnโ€™t exceed the rated capacity of your generator. Consult the manufacturer’s specifications for guidance. If an overload occurs, promptly shut off the generator, disconnect unnecessary appliances, and restart it to prevent damage and extend its lifespan.

2. Fuel Level

If your generator keeps shutting off shortly after starting, it could be due to low fuel levels. Keep the fuel tank filled to support continuous operation, topping it off before each use. Another option is to install a generator powered by natural gas or liquid propane. Both fuel options offer reliable fuel even during utility failures.

3. Low on Oil

Insufficient oil levels pose a serious risk to your generator’s health. Modern models often feature a low oil shutoff sensor that stops the engine to prevent it from running without proper lubrication. You can measure oil levels using the dipstick provided. If levels are low but the oil appears clean, try adding more oil to fix the problem.

However, if the oil is low and contaminated, an oil change is needed to prevent further damage. Knowing your generatorโ€™s oil level at any given time helps maintain safe and uninterrupted operation.

4. Defective Spark Plugs

If your residential or commercial backup generator constantly shuts off shortly after starting and you notice a crackling sound, it could signal dirty or defective spark plugs. The best solution is to replace them with new ones.

If the damage is minimal, a residential or commercial electrician might be able to fix and install the spark plugs to restore proper function. In any case, maintaining your generatorโ€™s spark plugs allows for smooth operation.

5. Choke Position

Setting the choke position correctly is crucial when starting a generator. It regulates the airflow to the carburetor while enhancing fuel flow, ensuring a balanced air-fuel mixture for a smooth startup.

Begin with the choke set to full when initiating the generator, transitioning to half choke after a brief period and eventually to the run position. Not making these adjustments can disrupt the air-fuel balance, causing the generator to shut off unexpectedly.

6. Dirty Air Filter

A generator needs a consistent supply of clean air to achieve optimal performance. The air filter plays an important role by blocking dirt and debris from entering the engine while allowing sufficient airflow.

If your generator keeps turning off, this is an indicator of a dirty air filter. This is a serious issue because a clogged filter can impede airflow. We recommend cleaning or replacing the air filter to restore proper airflow, ensuring the engine receives the clean air it needs to operate efficiently.

How to Increase the Life Cycle of a Generator

Generators play an important role in the life of your home, providing a backup power supply when utility power fails. With a backup generator on hand, you can continue using lights, appliances, and devices as usual.

As such a crucial piece of household equipment, you must take proper care of your generator to maintain peak performance and maximize its lifespan. Here are three steps you can take to achieve these goals:

Maintenance

The best way to maximize your generatorโ€™s lifespan is to maintain it. Routine maintenance allows you to identify components that need repairs early on to help you avoid more costly problems down the road. Many generator vendors offer extended warranties or maintenance contracts, providing opportunities for proactive care.

In addition to scheduled check-ups, we recommend running your generator for 30 minutes each week. This simple step ensures proper oil circulation throughout the system, which prevents wear and tear.

Itโ€™s common for individual generator components to malfunction or fail before the entire system shuts down. Routine maintenance provides a time for you to catch these initial problems before they have a chance to snowball, jeopardizing the condition and performance of your backup generator.

Regular Cleanings

Regular cleanings also contribute to generator longevity. Make sure the exhaust and intake fans remain free of debris, pests, and other obstructions, keeping plants and other objects from blocking essential generator components. Remove any snow accumulation from around your generator during the winter for the same purpose.

Continuous Oil and Battery Inspections

Regular oil and battery inspections help enhance the lifespan of your generator. Before and after each weekly 30-minute run cycle, use the dipstick to check the oil levels.

Closely follow the manufacturer’s recommendations for oil brand, filter type, and change intervals to maintain peak performance. Failing to adhere to these specifications can lead to costly and even permanent damage, which you want to avoid.

You should also safeguard the battery against corrosion and leakage. Any signs of corrosion or leakage should prompt immediate maintenance intervention. Top off the battery with fresh oil as needed to keep it in prime condition.
