How to Fix an Overloaded Generator?

Is your generator showing signs of being overworked and experiencing an overload?Searching for ways to remedy this issue? Look no further, as you’ve arrived at the perfect place for solutions.

Several factors can lead to generator overloads. Some models are more susceptible to this problem, so it’s essential to be aware of the causes and how to avoid them.

Let’s explore the steps on how to fix an overloaded generator together!”

How to Fix an Overloaded Generators

Overloaded Generator Signs

To determine if your generator is being overloaded, it’s important to be aware of certain warning signs. One indication that your generator is struggling to handle the load is if the circuit breaker trips.

This is a safety feature that will shut down the generator to prevent damage. Additionally, you may notice that the cooling fan becomes excessively loud or stops working altogether. Another sign of an overloaded generator is a humming noise that may be emitted. Furthermore, if you see smoke or sparks coming from the vents, this can be a clear indication that the generator is overheating and unable to cope with the demand.

If the generator powers lights, you may also observe that the light intensity fluctuates or that power outages occur. Finally, exhaust gases may contain soot, which is another indication that the generator is overloaded. If you notice any of these signs, it’s recommended that you take steps to reduce the load on the generator or seek professional assistance.

How to Fix An Overloaded Generator?

If you suspect that your generator is experiencing an overload, it’s essential to take immediate action in order to prevent damage to the equipment and ensure safe operation. Here are a few steps to follow to rectify the issue:

The first step is to disconnect all electrical devices connected to the generator. This will help to identify the source of the overload.

Evaluate whether the equipment connected to the generator is exceeding its capacity, if so, you may need to upgrade the generator or use different equipment

Press and hold the reset button on the generator to restart it.

Once the generator is restarted, monitor the load on the generator and reconnect the electrical appliances one by one, ensuring that the generator’s output is not exceeded.

If the overload warning persists, it may be necessary to repair or replace the generator.

Sometimes, the problem is not caused by an overload, but by a warning light that is triggered by a built-in short circuit in the generator. In such cases, the generator may need to be replaced to avoid future issues.

To ensure that the generator is operating safely, it’s recommend to schedule a check-up with an electrician after repair. They will be able to check the generator and the cables connecting it to your home’s appliances, and identify any potential issues that could cause an overload in the future.

Things To Keep In Mind To Avoid Overloading Generator

To avoid overloading your generator, it is crucial to take a proactive approach and keep the following things in mind:

Avoid pushing your generator to its maximum capacity and exceeding its power output capabilities. This can lead to damage to the generator and potential power outages.

By carefully balancing the generator’s load and demand, you can ensure a stable power supply and prevent overloading.

Make sure your generator is equipped with automatic voltage regulation (AVR) feature. It helps to prevent voltage spikes and drops, which can cause overload damage.

If you find yourself frequently overloading your generator by running multiple appliances at the same time, it may be time to upgrade to a larger generator that can handle the increased demand.

If your generator cannot be repaired and is still covered under warranty, contact the manufacturer for guidance and support.

Before connecting circuits directly to an outlet box, ensure that they are rated appropriately and follow the manufacturer’s instructions for using the generator. Additionally, avoid over-tightening connections when connecting power cords to prevent damage to the circuitry and excessive heat buildup from poor ventilation.

When replacing fuses and circuit breakers, always use the same specifications as the original.

Always be aware of the wattage of your appliances when calculating the amount of electricity they require. Some appliances, such as furnaces and refrigerators, require more power to start than to run, so make sure your generator can handle the starting wattage.

Regularly schedule check-ups with certified electricians to ensure that your generator and the cables connecting it to your home’s appliances are in good working condition. This will help you identify potential issues before they become a problem and cause an overload.

What to do when the generator is overloaded with nothing plugged in?

It is not uncommon for a generator to experience an overload even when nothing is connected to it, particularly after it has been running for a prolonged period without a load. This can be caused by various factors such as an internal component failure or a software issue.

To resolve this issue, the first step is to try resetting the generator. This can be done by turning it off and restarting it, and using the overload reset button. After the generator has stabilized, you can plug in a load.

If the generator continues to experience problems such as failing to power up or shutting down frequently, it may be indicative of a more serious problem. In such cases, it is recommended to contact the manufacturer’s engineer for professional repair. They can diagnose and repair the issue. It’s also advisable to have regular maintenance check-ups on your generator to prevent this kind of problem from happening.


Is there any generator overload protection?

Yes, some generators are designed to handle overloads and prevent damage to the equipment. These generators are equipped with specialized protection mechanisms such as a CT-secondary circuit breaker and a current transformer on the output. These devices monitor the current flowing through the generator and when an overload is detected, they act quickly to de-energize the generator field, thus preventing further damage and ensuring safe operation. This way the generator can withstand the overloads, and maintain the power supply without causing damage to the machine.

What is an automatic voltage regulator (AVR)?

AVR (Automatic Voltage Regulation) is a feature that helps to maintain a stable power supply to connected devices by regulating the voltage of the main electricity supply. It is particularly useful for preventing power fluctuations and damage to sensitive equipment. On the other hand, Line Interactive uninterruptible power supplies offer an additional layer of protection from power disruptions such as sags, brownouts, and surges. These power supplies work by maintaining a buffer of stored energy that can be used to keep connected devices powered during power disruptions. This ensures a stable and uninterrupted power supply to your equipment, even during power outages.


If you’ve read this article about “how to fix an overloaded generator” you should now have a better understanding on how to identify and solve this issue. Being vigilant for signs of overloading, as outlined in the article, is the best way to prevent damage to your generator and ensure stable power supply.

However, if you’ve taken the necessary steps to fix the overload, but the generator is still experiencing issues, it may be best to seek the help of a generator expert. They will have the expertise and equipment to diagnose and repair any underlying problems that may be causing the overload.
