ProParts Direct Learning Center | How to Keep Your Generator in Top Shape for Power Outages

Heavy storms, hurricanes, or simply an unexpected blackout can leave you quite literally powerless. Now that we rely on electricity to power everything from our home appliances to even keeping our work flowing from our home offices, a power outage can mean more than just a missed episode of your favorite TV show.

So, what can save you from stumbling in the dark? A power generator. But the generator isn’t going to fire up right when you need it the most if you have neglected it in your garage all year.

Here is a guide to the care and maintenance your power generator needs to remain in its optimum state when you most need it.

Where are Generators Stored?

You might already have thought about that dry, air-conditioned basement. Or maybe that dusty garage? Those aren't bad ideas, but not quite right either. Just like figuring out ways to stay cool when your AC is broken, knowing where to place a generator needs some strategic thinking.

Generators are best kept in places where they’re protected from harsh weather. But more importantly, they need ventilation. When running, engines stored in enclosed spaces like basements or garages can lead to a carbon monoxide buildup.

Find a well-ventilated location protected from the elements and easily accessible for refueling and operation. A good solution could be the use of a good portable generator.

How Often Should I Run My Generator?

To keep your generator in good working condition and ready to start at a moment’s notice, ensure it has a little run-out once in a while. Ideally, you should run the generator for about 30 minutes every three months to ensure all parts stay lubricated and batteries are fully charged. You can write down these check-up dates on your calendar to ensure you don’t miss them.

Generator Inspection: What Should You Look Out For?

To make sure your generator is in prime working condition, conduct regular inspections on several key components:

Generator Fuel: The first thing you’ll want to check is the fuel. Old and stale fuel can damage your generator’s engine. So, it's important not to let the fuel sit in the tank for too long. If you don’t use the fuel regularly, remember to drain it out and replace it with fresh fuel later.
Check for Leaks: Periodically give a once-over around your generator for any signs of oil or coolant leaks, which could signal some issues. Minor leaks might seem harmless, but if you leave them unattended over time, they’ll cause quite a bit of damage and create a potential fire hazard.
Filters and Oil Change: You should change the engine oil and filters according to the manufacturer’s instructions. Clean oil ensures smooth operation and also prolongs the lifespan of the engine by preventing dirt buildup, which can wear down your generator’s internal components.

This is usually done after the first 25 hours of use when it’s new and then after every 50 to 60 hours of running time. Keep in mind that this depends on the specific model.
Examine Fuel Lines: Fuel lines are critical to your generator’s operation as they transport the fuel from the tank to the engine. Over time, these lines could become clogged or damaged, leading to inefficient performance or even failures during use. Check for cracks, breaks, and debris that could hamper its function.
Take Care of the Battery: Batteries can lose their charge or become damaged over time. It’s important to check your generator’s battery for corrosion and also conduct occasional load testing to ensure it’s still packing a punch.
Check Coolant Levels: Keeping your generator cool is as critical to its performance as the fuel. A well-maintained cooling system helps prevent overheating during continuous operation. Regularly check coolant levels and top it off whenever needed.

How Can I Clean My Generator?

Generators aren’t high maintenance, but they do need a bit of attention from time to time. You want to focus more on dusting it off rather than giving it a deep clean. Dust accumulation could block air filters, which could cause overheating issues.

Gently brush or use compressed air cans to blow away dirt or any cobwebs that might have formed during storage. Pay special attention to the ventilation areas and exhaust outlets. However, if you face heavy soot residue build-ups around the exhaust system, consider getting professional help.

Extreme weather can cause rust to form on the generator's metal parts. Periodic checks can help you catch any signs early enough before they cause significant damage.

Also, remember: Keep water away when cleaning! Water exposure may cause short circuits and severe damage if it comes into contact with electrical components inside your generator.

What about Generator Repair and Troubleshooting?

Even with all this regular maintenance, sometimes hiccups happen. So, how do you troubleshoot and repair your generator?

First things first: always refer to the user manual. Your manufacturer’s booklet will prove to be indispensable for troubleshooting common issues specific to your model. If you cannot find that old booklet (since we rarely keep track of them), most companies offer their manuals online.

But let's give you some pointers:

Generator not starting: This could often be caused by a lousy battery connection or low fuel level. Ensure your battery is charged and has sufficient power before attempting a start-up.
Poor output or power surges: This could potentially indicate an issue with the alternator or possibly broken capacitors/resistors, requiring professional attention.
Overheating risk: If your engine overheats, it might signal insufficient coolant, blockages in airflow around the unit, or clogged filters hampering efficient cooling.
Loud operation noise: If your generator is making too much noise that it normally doesn't make, this can indicate things like loose components, so you may have to check screws and bolts around engine mounts and other fittings for looseness. Overly worn-out parts would need to be replaced in this case.

Keeping the Lights On

While we tend to think of generators as a backup plan and put them away for months on end, giving them a little attention from time to time can make all the difference.

From periodic inspections and fuel checks to catching any leaks in advance, keeping your generator in optimum shape will ensure you won’t be left in the dark when a power outage occurs.
