How to Troubleshot Generac Generators

Generac generators are known for their reliability and durability, but like any piece of machinery, they can experience problems from time to time. If your Generac generator is not working properly, there are several steps you can take to troubleshoot the issue.

Step 1: Check the Fuel Supply

The first step in troubleshooting a Generac generator is to check the fuel supply. Make sure that there is enough fuel in the tank and that the fuel is fresh. If the fuel is old or contaminated, drain the tank and replace it with fresh fuel.

Step 2: Check the Oil Level

Next, check the oil level in the generator. The oil level should be between the minimum and maximum marks on the dipstick. If the oil level is low, add the appropriate type of oil according to the manufacturer's recommendations.

Step 3: Check the Battery

If the generator is not starting, the problem could be a dead battery. Check the battery terminals for corrosion and make sure that the battery is fully charged. If the battery is dead, replace it with a new one.

Step 4: Check the Air Filter

A dirty or clogged air filter can cause the generator to run poorly or not start at all. Check the air filter and clean or replace it if necessary.

Step 5: Check the Spark Plug

A faulty spark plug can also cause the generator to run poorly or not start at all. Check the spark plug and replace it if necessary.

Step 6: Check the Fuel Filter

A clogged fuel filter can prevent the generator from starting or cause it to run poorly. Check the fuel filter and replace it if necessary.

Step 7: Check the Carburetor

If the generator is still not working properly, the problem could be a clogged carburetor. Remove the carburetor and clean it with carburetor cleaner.

If these troubleshooting steps do not resolve the issue, it may be necessary to take your Generac generator to a professional for repair. Generac also has a customer support team that can help troubleshoot and provide guidance for more complex issues.
