My Generator Won't Start — What Do I Do?
Generators are a great way to keep the lights on in case of a power outage. However, there are times when generators won’t start, preventing them from operating when they are needed most and, in turn, causing your appliances and electronics not to function correctly.
There are multiple reasons why a generator might stop working, so trying to pinpoint the exact reason why can be tricky. Here are eight problems a generator inspection might find that explain why your generator is not working correctly.
The Fuel Tank Is Empty
One reason why your generator is not running is relatively simple: there is no gasoline left in the fuel tank. Without enough gasoline, a generator won’t be able to run correctly. Regardless of whether there is still propane or natural gas in the generator, there might not be enough to feed it.
In some circumstances, it’s also possible that a generator won’t start even if it has enough fuel. Stale gasoline that’s lingered in a fuel tank for two months or more can be unusable and even damage the engine by creating clogs and other problems. Replacing the tank’s fuel with a fresh supply can help get it starting again.
Engine Is Out of Oil
Oil is also an important fuel source for engines and can become problematic if it isn’t properly maintained. Some engines have a built-in sensor that can detect when oil levels are too low, and if they are, the generator will shut down automatically. Sometimes, if the engine is on an uneven surface, this sensor will mistakenly indicate that the oil level is too low, even if there’s enough, and the generator will refuse to function.
Other factors may influence the engine’s oil supply, such as a leak in the tank or an old filter, which can be fixed or replaced with the help of a professional.
The Battery Is Bad
Some generators have an electric starter and require a battery to function, and if that battery is out of charge, the starter won’t work. Using a battery charger can replenish its charge, but you may need to replace it entirely if it’s dead. Also, keep in mind that using a bad battery can have numerous consequences for an engine’s overall condition.
A Dirty Air Filter
In order for engines to work properly, they must have enough air to start ignition. If the air filter is dirty, it may severely limit the machine’s airflow. Cleaning away any dust and debris that has built up should help, but the filter may need to be replaced entirely. Though an engine can receive air more easily if the dirty air filter is removed, it is dangerous to run it without an air filter in place.
You Used the Wrong Extension Cord
Believe it or not, an extension cord might be the source of a generator’s problems. Portable generators typically need a cord with a ground fault circuit interrupter (GFCI) of 14-gauges. If you aren’t using the intended type of extension cord, fire or electrocution may occur because electricity is flowing to where it shouldn’t. Older and worn-out cords can also be the source of the problem, so don’t hesitate to purchase a new one if necessary. To learn more about what type of extension cord your home’s generator needs, consult a professional for guidance.
The Inverter Sustained Damage
Inverter engines can also suffer from damage. An inverter throttles up and down electronically to be more efficient, so owners don’t have to fill it up with gas nearly as often. Operating an inverter engine, or any engine, during inclement weather can cause water to enter the electrical panels and potentially short circuit them. To prevent this from happening, ensure your generator is located on dry and level ground.
Devices Are Defective
Another possible reason why your generator won’t start is that key components are broken. When certain parts don’t work correctly, you can’t start the engine even if the most important parts are in order. Here are several parts you should ask an inspector to look at, and if they’re broken, seek professional repairs.
- Low Oil Sensor
- On-Off Switch
- Safety/Start Switch
