How to Troubleshoot Common Standby Generator Issues?

Standby generators are essential for homes and businesses that require a reliable power source during outages. However, like any other machine, they can encounter problems. Knowing how to troubleshoot these common standby generator issues can save you time and money.  This guide will cover some typical problems and how to fix them easily.

Check the Basics First

Before diving into complex troubleshooting, start with the basics. Make sure your standby generator is receiving power. Check if the wire light switch is turned on. If it isn’t, turn it on and see if the generator starts. Sometimes, the simplest solutions are the most effective.

Inspect the Fuel Supply

One of the most common issues with standby generators is a lack of fuel. If your generator won’t start, check the fuel tank. Ensure it is filled with the appropriate fuel type. For propane generators, check the tank level. For diesel or gasoline models, make sure the fuel is fresh. Old or contaminated fuel can cause starting problems.

Check the Battery

Another frequent issue is battery failure. Standby generators rely on batteries to start. If your generator is not starting, check the battery first. Look for signs of corrosion on the terminals. Clean any corrosion with a wire brush. Make sure the battery is fully charged. If it is dead, replace it with a new one.

Examine the Control Panel

The control panel on your standby generator provides vital information. It shows error codes, which can help you troubleshoot. If your generator has an error code displayed, refer to the owner’s manual. Each code will explain the issue. Follow the steps provided to resolve the problem.

Look for Overload Issues

Standby generators have a specific capacity. If you try to run too many devices at once, the generator may overload. This can cause it to shut down. Check the total wattage of the devices you plan to use. Ensure that it does not exceed the generator’s capacity. If it does, unplug some devices and try again.

Inspect the Circuit Breakers

Sometimes, the issue is with the circuit breakers. If the generator is not producing power, check the breakers on both the generator and the main panel. Reset any tripped breakers by switching them off and then back on. If a breaker keeps tripping, there may be a more serious issue that needs professional help.

Check for Faulty Wiring

Faulty wiring can cause several problems in your standby generator. Inspect all the wiring connections to ensure they are secure. Look for any signs of damage, such as fraying or burn marks. If you find damaged wires, replace them immediately. If you are unsure about handling electrical work, it’s best to call a professional.
