5 Common Reasons For Generator Failure & How To Prevent It

If your knowledge of generator usage and maintenance is not completely up to date, there is a chance you may encounter generator failure at some point during your ownership. Fortunately there are some very common reasons that generators fail and many of them are easily preventable with a little foresight and know-how. Here are some of the reasons why generators fail and some tips on how to stop them from breaking down.

Battery failure

The majority of all generator failures is a result of the battery failing. This is usually due to sulfation build up, which is when lead sulphates accumulate on the batteries. To prevent this, inspect your battery regularly and remove any corrosion before it begins to amass around the battery.

Coolant Leak

Leaking coolant is another very common reason that your generator will stop working. If there is a low level of coolant, the generator will often shut down in order to prevent it becoming damaged beyond repair. Again, periodic inspections of your generator should alert you to any signs of leaking coolant – check for any puddles around the machine (the colour of the coolant varies depending on the type of generator so make sure you know what colour coolant you are looking for).

Oil Leak                                       

An oil leak in a diesel generator is not usually an oil leak but rather the result of what is known as ‘wet-stacking’. Low temperatures in the combustion chamber of the generator can lead to wet-stacking – when the generator is not run at full capacity, particles of carbon, lubricant and unburned fuel can build up and affect your generator’s performance levels. Ensuring you choose a generator that meets your precise needs can help you to avoid this situation.

Air In The Fuel System

This is a scenario you should really try and avoid as it can be very tricky to remove and air lock from your fuel tank. If you do not use your generator regularly, simply switching it on a running it for a short period of time once a week should be enough to prevent any air from getting into the fuel system. This is a more common issue for generators which are only used sporadically.

Run Out Of Fuel

This may seem pretty obvious but it can happen – no fuel means no power so always keep an eye on your generator’s fuel levels to avoid running out of fuel. Some generators come with alarms if your generator is starting to run low on fuel so check these are working too.
