Commercial diesel generators are used to provide backup power in case the power grid goes down. They are also used in hospitals, schools, and other places with sensitive equipment that needs constant power.

The life of commercial diesel generators is not indefinite. After some time, it will need to be replaced. It cannot be easy to know when it’s time for a replacement, but there are some signs you can look for that will help you make this decision. Here are several signs you need to replace your commercial diesel generator:

Your Generator Doesn’t Turn Over Anymore

The first sign that you may have a problem with your diesel generator is if it no longer starts.

If you notice that your generator won’t start at all, you should immediately contact a professional electrician specializing in generators. You don’t want to wait until you lose power before getting help!

Your Generator Makes Loud Noises

Another sign that something is wrong with your generator is if it sounds like it’s making a lot of noise.

If you hear a high-pitched whine from your generator, you should call a professional immediately.

A noisy generator could mean several things, including worn bearings, bad fuel pumps, belts, or even a broken engine.

Your Generator Runs Out Of Oil

If your generator suddenly runs out of oil, you should take action immediately. A lack of oil can lead to problems with your generator’s internal parts, causing them to wear down faster and break sooner than normal.

If you’re worried about running out of oil, make sure that you regularly check your generator to ensure that it still contains enough oil.

Your Generator Smells Bad

Your generator might smell really bad if it hasn’t been properly maintained. Make sure you clean out any filters on your generator, especially if they look dirty or clogged.

Also, make sure you change the air filter inside your generator once every month. Finally, keep an eye out for leaks around the seals where the coolant flows through.

These seals can leak, and if left unattended, they could cause serious damage to your generator.

Your Generator Is Covered In Rust

Rusty metal is not only unsightly, but it can also be dangerous. Rusting components could pose a risk to people who work near your generator, and it could also pose a fire hazard. So if your generator looks rusty, you should remove it immediately.

Your Generator Isn’t Producing Enough Electricity

When you use your generator, you’ll likely notice that it produces less electricity than usual. If you notice that it produces less electricity, you should immediately call a professional electrician.

If your generator isn’t producing enough power, you could have several issues, including a failing alternator, a faulty regulator, a bad battery, or a blown fuse box.

Your Generator Isn’t Generating Enough Voltage

A low voltage can indicate that your generator is having trouble starting. Low voltage can also mean that your generator isn’t providing enough electrical current to operate properly.

If you notice that your generator’s voltage level is dropping, you should immediately stop using it and call a professional electrician immediately.

Your Batteries Are Dying

If you notice that your batteries are starting to die off, it’ll probably be best to invest in new ones.

Batteries are extremely expensive, and if you’re using them to store electricity while your diesel generator isn’t working properly, then you’re wasting money.

Your Have Old Generator

The older your generator gets, the more likely it is to develop problems. As a result, you need to replace your old generator as soon as possible.

However, there are some signs that your generator needs to be replaced. For example, if your generator has developed a crack, then it will probably need to be replaced.

In addition, if your generator doesn’t produce enough power, then it may need to be replaced.

You Notice That Your Generator Is Leaking

Leaks are one of the most common problems that commercial diesel generators face. Leaks can occur when the seals on your generator become damaged over time.

This means that your generator can no longer prevent moisture from entering the system. When this happens, the seals can start to deteriorate, which leads to leaks.


A commercial diesel generator gives your business reliable power when the grid goes down. It also saves you money by eliminating the need for costly utility bills.

Unfortunately, as your company grows, so does its reliance on a commercial diesel generator. When you don’t replace your older generators, you lose out on opportunities to save money and increase productivity. You’ll need to invest in new generators to ensure your company stays ahead of the competition.
