Why a generator won’t start

Well, if you are facing a situation where your generator won’t start, the first thing you have to do is not panic and examine your generator properly. The generator won’t start due to a lot of reasons such as dirty spark plug, low oil level, clogged carburetor, etc. You must know about these reasons so that you can fix the problem and start your generator. Let’s check out what are these reasons and how you can fix the problem that occurs in your generator.

common Reasons your generator won’t start

Your generator won’t work properly or even won’t get started due to many reasons. These reasons are given below in this article:

1. Low fuel tank

The first and the most important reason for a non-running generator is its low fuel level in the fuel tank. If your fuel level is low in the tank your generator won’t be able to start.
The solution to this problem is that you can add more fuel into the fuel tank and raise the fuel level in your tank. And your generator starts to work again.

2. Low engine oil

The oil level of the engine should be high for better working of the generator. If your generator won’t start, the engine oil level may be low. Most advanced generators have come with oil level sensors that tell you about the level of oil in your generator’s engine.

3. Battery is dead

Another reason that can stop the working of the generator is its battery. If the battery of your generator is dead then you can’t start your generator. For this purpose, you should charge the battery of your generator through a DC source.

4. Plugged cables

One important thing you should care about is that the cables of your generator shouldn’t be plugged in when you start your generator. If your cables are plugged in then no other device can connect to the generator. Therefore, try to plug out all the wires before you start your generator.

5. Choke adjustment

Any kind of problem in the choke of the generator also stops the working of your generator. The choke is usually used to maintain the level of air inside the carburetor of the generator. The generator won’t get started if the amount of air is low for combustion. Adjusting the choke of your carburetor can give you a positive response if your generator won’t start.

6. Low air level

If your generator is still not working after you adjust the choke, then another reason for the low air level in your generator would be a clogged air filter. If your air filter is clogged then your generator won’t get enough air for the combustion of fuel and won’t start. To start your generator just replace the old air filter.

7. The spark plug is dirty or damaged

A dirty spark plug can also be a reason if your generator won’t start. When your spark plug is dirty or damaged your engine won’t receive enough start for combustion of fuel and won’t start. In this case, you can either clean your spark plug with brushes or remove all the dirt from it. Or you can change the damaged spark plug with the new one. So, that you can start your generator.

8. The carburetor and fuel valves are clogged

Your generator won’t get started if the carburetor and the fuel valve of your generator are clogged. To restart your generator again you simply unplug the valve and check whether the fuel is flowing through the valve or not. Moreover, your carburetor is clogged when you don’t change the fuel for a long time.
