When your generator stops working, it can feel like a major headache. Whether you rely on it during power outages or for your business needs, a malfunctioning generator can disrupt your day. But don’t worry! Troubleshooting and repairing your generator is often easier than you think. I’m here to walk you through the most common issues and how to fix them. Let’s get your generator back up and running smoothly!
Understanding Your Generator Troubleshooting Guide
Before diving into repairs, it’s important to understand how your generator works. Most portable generators run on gasoline or propane and have several key components: the engine, fuel system, spark plug, air filter, and battery (for electric start models). Problems usually arise in one of these areas.
Here’s a quick checklist to keep in mind when troubleshooting:
Fuel: Is there enough fuel? Is it fresh?
Spark Plug: Is it clean and properly gapped?
Air Filter: Is it clogged or dirty?
Oil Level: Is the oil at the right level and clean?
Battery: Is it charged and connected properly?
By checking these basics first, you can often identify the root cause quickly.
Common Generator Problems and How to Fix Them
Let’s break down the most frequent issues you might face and how to solve them step-by-step.
Generator Won’t Start
This is the most common complaint. Here’s what to check:
Fuel Supply
Make sure your generator has fresh fuel. Old gasoline can cause starting problems. Drain old fuel and refill with fresh gas if needed.
Spark Plug
Remove the spark plug and inspect it. If it’s dirty or worn, clean it with a wire brush or replace it. Make sure the gap is set correctly according to your manual.
Choke Position
Ensure the choke is in the correct position for starting. Usually, it should be closed when starting a cold engine.
Battery (Electric Start Models)
Check the battery charge and connections. A weak battery can prevent starting.
Generator Starts but Shuts Off Quickly
If your generator starts but then dies, try these fixes:
Fuel Quality and Flow
Check for clogged fuel lines or filters. Replace filters if dirty.
Air Filter
A dirty air filter can choke the engine. Clean or replace it.
Oil Level
Low oil can trigger a safety shutoff. Check and top off oil as needed.
Generator Produces Low or No Power
If your generator runs but doesn’t provide enough power:
Overload
Make sure you’re not exceeding the generator’s wattage capacity. Unplug some devices and try again.
Voltage Regulator
A faulty voltage regulator can cause power issues. This may require professional help.
Loose Connections
Inspect all wiring and outlets for loose or damaged connections.
When to Call a Professional for Generator Repair
Sometimes, the problem is beyond simple fixes. If you’ve tried the basic troubleshooting steps and your generator still isn’t working right, it’s time to consider professional help. Issues like a faulty voltage regulator, engine mechanical problems, or complex electrical faults require expert attention.

Tips to Keep Your Generator Running Smoothly
Preventing problems is always better than fixing them! Here are some simple maintenance tips to keep your generator in top shape:
Regular Oil Changes
Change the oil after the first 25 hours of use, then every 50-100 hours depending on your model.
Use Fresh Fuel
Never use fuel that’s over six weeks old. Never let your generator sit without at least starting it and running it once every two weeks for five minutes.
Clean or Replace Air Filters
Check air filters every 25 hours of use and clean or replace as needed.
Inspect Spark Plugs
Check spark plugs every 100 hours or annually.
Run Your Generator Periodically
Running your generator for 5-10 minutes every 2 weeks helps keep the engine lubricated and ready.
Store Properly
Keep your generator in a dry, covered area to protect it from dust and moisture.
Staying Prepared with Your Generator
Having a generator is a great way to stay prepared for power outages or outdoor projects. But it’s important to know how to troubleshoot and maintain it. With these tips and steps, you can handle most common issues yourself and know when to call in the pros.
Remember, regular maintenance and quick attention to problems will extend your generator’s life and keep it ready when you need it most. If you ever feel stuck, don’t hesitate to reach out to experts who can provide fast and reliable service.
