Frequently Asked Questions

When your home generator refuses to start, it can be a source of frustration, especially when you need it most. At Mainstream, your peace of mind during power outages is our priority. Here’s a quick guide to the 10 most common reasons your generator might not be starting, and remember, our team is always here to help with any of these issues:

  1. Low Oil Level: Check and top up the oil if it’s low. Remember, generators need a level surface to accurately measure oil.
  2. Out of Gas: Ensure there’s enough fresh gasoline in the tank. Avoid using gasoline older than two months.
  3. Incorrect Choke Lever Position: Adjust the choke lever to the correct position for starting, based on whether the engine is cold or warm.
  4. Closed or Clogged Fuel Valve: Open the fuel valve to allow gas flow. Check for clogs if the problem persists.
  5. Clogged Carburetor: Old gasoline can gum up the carburetor. Clean it out or drain it if the generator has been idle for a while.
  6. Spark Plug Issues: Replace the spark plug if it’s dirty or malfunctioning to ensure a strong ignition.
  7. Faulty Low-Oil Sensor: Disconnect the sensor to check its function. It might need a reset or replacement.
  8. Dead Battery: For electric start models, recharge the battery with the pull starter or a charger if needed.
  9. Plugged-in Electronics: Unplug all devices from the generator before starting it to prevent overload.
  10. Dirty Air Filter: Clean or replace the air filter to ensure proper air flow for ignition.

Whether you’re looking to use a generator at your home, workplace, or for a recreational vehicle, there are a few factors to consider:

The Different Types of Home Generators

There are plenty of home generator options to choose from, including whole-home standby generators; large, medium, and small inverters; portable generators, and more.

Whole-home standby generators: Many standby home generators are powered by natural gas, and switch on automatically in a power outage without requiring refueling.

Inverters: Inverters cover a wide range of uses and can power anything from a few appliances to a whole small house.

Portable generators: Portable generators usually offer the best value for your dollar, but are often limited in their output.

Generator Sizes

The size of the home generator that you choose to buy depends mostly on what you’ll be using it for.

If you need a home generator with capacity to power your entire home for prolonged periods during an emergency, then you’ll probably need what’s called a standby generator. These are permanently installed outside your home, and are generally the most expensive option.

Large and medium inverters are another good option if you’re only looking to power a few key appliances during a power outage.

Calculating the Amount of Power You Need

Your home generator should be able to power the combined wattage of all of the appliances you want running when the power goes out. Calculating exactly what wattage you need can be tricky, and is potentially dangerous if calculated incorrectly. The generator installation experts at Mainstream can help you decide exactly how much power your home needs with a personalized home generator installation proposal.
