How to Schedule Generac Generator Weekly Test [Troubleshoot Common Errors]

Most of the time our generator does not start during power outages, frustrating users who rely on them for power.

Generac generators have addressed this issue by introducing: the self-testing feature. These generators can perform automatic self-tests once a week or per user schedule. 

During these tests, the generator independently checks its essential components and systems. It ensures that everything is in optimal operating condition. It will show on the control panel screen if any issue is found.

Let’s check how to conduct a Generac generator weekly test and how to troubleshoot common issues.

What is Generac Generator Weekly Test?

This test is executed automatically by the generator every week, The Weekly Test on Generac Generators ensures ⁠ the generator is reliable and working correctly.

Your generator goes through a short test every week to ensure it’s in good working order. This test, which usually lasts about 20 minutes, checks the engine, battery, and electrical systems to ensure they all work correctly. 

If there are any problems, they’ll be caught during this test and can be fixed before they cause a power outage. So, rest assured that your generator is always ready to keep your lights on when you need it most.

Suppose the generator’s self-testing system detects problems during the Weekly Test. In that case, it will usually display error codes or error messages on the control panel. These messages provide valuable information to the owner or maintenance personnel so that they can diagnose and address the underlying issues promptly.

The Weekly Test is a great way to avoid potential generator problems. By running a few simple tests once a week, you can catch any issues early on and prevent them from becoming more significant problems. This will help keep your generator running smoothly and reliably, so you can always count on it when needed.

To ensure the long-term performance and durability of your Generac generator, follow the manufacturer’s guidelines for weekly testing and maintenance. Regular testing and maintenance can significantly contribute to your generator’s longevity and trouble-free operation, making it a dependable solution for power outages and emergencies.

Here are some of the benefits of the Weekly Test:

  • It can help to prevent costly repairs.
  • It can extend the life of your generator.
  • Knowing that your generator is always ready to go can give you peace of mind.

So if you have a generator, schedule a Weekly Test today!

Sure, you can schedule a Monthly Test on Generac Generators. It’s just like setting up a Weekly Test, but instead of selecting “weekly,” you’d choose “monthly”.

While you can schedule a monthly test, Generac and many experts recommend weekly tests as the default setting. This is because weekly tests help ensure your generator is in optimal condition and will work when needed.

A reminder that if you don’t use your generator very often, it’s essential to run a weekly test for 10-15 minutes. This will help keep the engine and other components in good working condition. 

Whether to schedule weekly or monthly tests for your generator depends on how often you use it and what the manufacturer recommends. 

It’s essential to consider the specific model of your generator and follow the recommended maintenance practices to ensure its optimal performance and longevity.
