How to Fix an Overloaded Generator?

Share on:

Is your generator overloaded? Do you want to find out how to fix an overloaded generator? In that case, you have come to the right place.

There are a number of factors that can cause generator overloads. In some generator models, overloading can be more likely, so you need to be aware of what causes overloads and what you can do to prevent them.

How to Fix an Overloaded Generators

Come on, let’s start!

Overloaded Generator Signs

These signs should be noticed when you want to know if your generator is overloading

  • In the event of an overloaded generator, the circuit breaker will trip.
  • The generator will shut down
  • The generator’s cooling fan may become too noisy or stop turning. An overloaded generator will emit a humming sound.
  • In addition to the smoke coming out of vents, there may also be sparks shooting under its cover.
  • The generator may also become overheated.
  • In the case of a generator powering lights, you may notice that the light intensity fluctuates or the light even goes out and on, a clear sign that the generator is struggling to cope with the load.
  • Exhaust gases contain soot.

Whenever you see any or all of these signs in your generator, then unluckily your generator is overloaded.

How to Fix An Overloaded Generator?

As soon as you noticed the overloaded generator signs described above, you can fix the overloaded generator by following these steps:

  • The first thing to do is to disconnect all generator-connected equipment.
  • Find out whether the overload condition is due to the overloading capacity of the equipment.
  • In order to re-start the generator, you must hold the reset button switch for a few seconds.
  • After restarting the generator, if an overload warning goes off, make sure you don’t exceed the generator’s output after reconnecting the electrical appliances.
  • If you still see the overload warning light, the generator needs to be repaired, since it might not be an overload but something else.
  • In some cases, the problem doesn’t stem from overload, but from warning lights triggered by a shortcut built into the generator. Such a generator will need to be replaced.
  • As soon as you have repaired your generator, and it hasn’t failed since the repair, consider having it inspected by an electrician. It will help to make sure the generator and the cables connecting it to your home’s other appliances do not have any problems, or else you may suffer an overload at a later time.

Things To Keep In Mind To Avoid Overloading Generator

It is important that you keep these things in mind if you want to avoid overloading your generator:

  • Do not run a generator at its maximum capacity, or overload it past its capacity to produce power.
  • By matching the generator load and demand, you can avoid generator overload, providing a more reliable power supply.
  • Make sure your generators are equipped with automatic voltage regulation (AVR) to prevent voltage spikes and drops. It is more likely for generators without AVR to experience overload damage.
  • When you keep overloading your generator by running a lot of appliances at the same time, it is advisable to get a bigger generator.
  • The manufacturer should be contacted if your generator cannot be repaired, and it is still covered under warranty for guidance
  • Ensure that the circuits in a generator are rated appropriately before they are connected directly to an outlet box, and follow the manufacturer’s instructions on how to use the generator. Additionally, avoid excessively tightening connections when connecting power cords to avoid damaging circuitry or accumulating extreme heat from improper ventilation.
  • You should use the same fuses and circuit breakers when you replace them.
  • Make sure you check the wattage of your appliances when you are calculating the amount of electricity they require. For appliances such as furnaces, refrigerators, etc., the power to start is greater than the power needed to run. The generator must at least meet the starting wattage.

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

When nothing is plugged into the generator, the overload light will sometimes come on or the generator may shut off. A generator will often experience this after running for some time without a load. It doesn’t happen often but may result if the generator runs for a long time without being loaded.

  • In such a case, resetting the generator may be necessary.
  • The generator should first be reset by turning it off and restarting it.
  • Be sure to reset the generator before restarting it using the overload reset button.
  • Plug in a load once it has stabilized.

If a generator fails to power up or keeps shutting down, there is a possibility that it may be faulty and requires professional repair. You can contact a generator manufacturer’s engineer to fix it if possible.
