In the event of a power loss, which frequently happens during the winter, a power generator could be your lifeline. At this point, we understand the criticality of this power backup equipment.
While there are a number of options on the market, Generac is the only company that has endured and has remained a pioneer in offering the highest-quality power generators. In terms of results, durability, efficiency, and cost-effectiveness, its backup power supplies are the best in their class. It makes sense that Generac generators have become known as one of the most reliable generator brands.
These are devices that are prone to malfunctioning at some time in their lifespan despite their robustness and capacity to operate in the harshest weather conditions. And many people ask why is my generator not producing power.
And although machines are designed to work, there could be a number of factors that lead to them conking down, so you must take the proper preventive measures to guarantee that they continue to function as effectively as possible.
The easiest way to prevent a generator from having trouble starting is to keep utilizing it frequently. This enables the machine’s mechanical components to keep running smoothly.
Generac generators are no different from other machines regarding wear and tear when not in operation. Here are some steps you may take to ensure that your Generac generator starts up again and runs as efficiently as possible.
Why won’t my generator start?
Low oil pressure
Any engine needs oil to function properly, and generator engines are no different. Oil is one of the most crucial parts. Your generator won’t start easily if the oil level drops below the acceptable level. To keep the generator functioning, you must replenish the oil.
You can also determine whether it’s time to replace the oil. The prevention of future hiccups can be achieved by routine oil changes. Check the location of your generator, as well. The low oil sensor could give an inaccurate result if it is placed on an uneven surface. Make sure it is installed on a flat surface.
Empty Fuel tank
This is a typical scenario, particularly in regard to power producers. Only a few areas employ generators as a daily backup power source.
Generators are typically only utilized whenever there is a power failure, which occurs occasionally. Therefore, there is a good probability that a generator will run out of fuel. Verify the gasoline level and top off the tank if necessary.
Choke is faulty
Another crucial element in the starting process of an engine is the choke. When starting the engine, it should be in the closed position, and it should only be turned on once the engine has warmed up. Depending on the manufacturer, the choke levers are placed at various locations in different generators.
Typically, the generator’s side air filter is directly above where the choke lever is located. It is included in the power management knob of several other generators. No matter where you have it, it needs to be turned off when you power the generator.
The fuel valve is blocked
If the generator won’t start even with the fuel tank full, there can be a problem with the fuel valve. The fuel will not reach the carburettor if the valve is closed or clogged, and the engine will not start.
When starting the generator, make certain that the fuel valve is open. There are two things you can do if the fuel valve is clogged. Make sure the vacuum relief valve has been opened if your generator has one.
The outlet hose should then be disconnected from the intake side. To ensure that the fuel can get to the carburettor, check to see if any of these lines are clogged and clear them.
Carburettor is obstructed
It almost seems like a cyclical procedure to fix a machine. Until you get to the root of the problem, you handle one problem at a time. If your generator still won’t start after you’ve made sure the fuel tank is clear, examine the carburettor. The carburettor may become clogged if your generator hasn’t been operated for a while without being drained.

After cleaning the carburettor and the carburettor drain, you must first turn off the fuel valve in order to fix it. You should use a carburettor cleaning frequently and use your generator at least once a month to prevent carburettor congestion. As a result, your machine will be in better health.
Generac Generator Repair
Replacement or repair of the spark plug is required
The spark plug accumulates a lot of carbon buildup over time, which could affect how well it functions. The engine won’t start if there is a spark plug problem. The residues can be removed by cleaning them with a little knife. By withdrawing the recoil starter and placing the spark plug near the engine when cleaning is complete, you may check the spark plug.
When the engine is clean, remove the recoil starter and hold the spark plug close to the engine’s crankcase to examine the spark plug. A spark plug tester can be used in addition. You are in good shape if the sparks appear solid and blue in hue.
Ensure that the spark plug wire is in a good position by taking a quick glance at it as well.
You need to inspect the ignition coil if the sparks aren’t powerful enough. Use an ignition coil tester to perform this. The ignition coil might need to be replaced if the issue persists.
If the equipment is not used for a while, the battery is known to deplete over time. Therefore, if your generator won’t start, you must assess the battery’s condition. You may need to change the battery if it is old. Jump-starting the battery will sometimes fix the problem. In this situation, you must make sure to regularly utilize your generator to prevent the battery from discharging.
Check and add fuel.
Old, stale fuel is among the most common causes of generator non-starts. If fuel has been kept in your Generac generator for more than 30 days without a fuel stabilizer or more than six months with a fuel stabilizer, a licensed repair dealer might need to clean the carburettor.
Always use brand-new unleaded fuel, please. Use only fuel with an octane rating of 87 or higher. Never use E85 fuel or a gasoline/oil blend intended for two-cycle engines.
After making sure your fuel is clean and your carburettor is clean, make sure you have enough fuel in your tank to start your generator—at least 1/4 of a tank.
Fuel valve location
The fuel valve should be turned on after you’ve checked the fuel level. The engine will run incorrectly and no fuel will be saved by partially closing the fuel valve. Make sure your fuel valve is fully on as a result.
Put Oil in
You should first confirm that your Generac generator is on level ground before checking the oil level. In doing so, the oil sensor will be able to assess whether there is sufficient oil to power the generator. Underneath the oil cap, the oil monitor is mounted. High or low oil levels are indicated by the letters “H” and “L” on it.
If your unit is low on oil, detach the oil cap and carefully refill it.
Turn On The Choke
Set the choke to half or off for a warm, recently used device. Set it to full choke, on the other hand, for a cold unit.
