Why Onan Generator Won’t Crank?

If you’ve recently experienced trouble with your Onan generator failing to crank, then you’re not alone. This issue is one of the most common problems encountered with Onan generators, and it can be caused by a variety of different factors. In this article, we’ll explore the potential causes for why an Onan generator won’t crank so that you can diagnose and fix the problem quickly.

Causes of a generator that won’t crank

  • Low or Discharged Battery: One of the most common causes for a generator that won’t crank is low or discharged battery. Check the voltage on your Onan generator’s battery and make sure it is at least 12 volts.
  • Corroded Battery Terminals: Another possible cause for generators that don’t crank is corroded battery terminals. Make sure to clean them regularly using baking soda and water, as well as a wire brush if necessary.
  • Dirty or Clogged Fuel Filter: The fuel filter in an Onan generator can become clogged due to dirt and debris buildup. If this happens, the fuel will not be able to flow properly into the carburetor, causing your generator to not start up properly. Make sure to replace your fuel filter regularly.
  • Faulty Spark Plug: A faulty spark plug can also be the cause of a generator that won’t crank. Make sure to check the spark plug every few months, and replace it if necessary.
  • Clogged Carburetor: The carburetor in an Onan generator can become clogged due to dirt and debris buildup, preventing proper airflow into the engine cylinders. This will ultimately prevent your generator from starting up properly. Cleaning or rebuilding your carburetor is one possible solution for this issue.

What to do if your Onan generator won’t crank

Before attempting any repairs to your Onan generator, make sure to check the manufacturer’s manual or website for troubleshooting tips and instructions. If all else fails, you may need to contact a professional service technician who can diagnose and repair your generator more effectively.

Once you have identified the cause of why your Onan generator won’t crank, you can then begin applying the necessary fixes. Make sure to follow all safety precautions when working on your generator and take extra care when handling tools and parts. With proper diagnosis and maintenance, you should be able to get your Onan generator back up and running in no time!
