There are a number of different problems that can affect generators. We’ve listed some of the more frequent to help you determine when you need to call for repairs:

Leaking fuel: Generators can use a variety of fuels, but any sort of fuel leak is major problem. It will lead to the unit losing its fuel supply and ceasing to work. Even with a natural gas generator, which receives fuel from the municipal source and therefore can’t run out if it, a leak is trouble, since it presents an explosive hazard. If you smell traces of fuel around your generator or see it leaking, shut off the unit and call for repairs right away.

Failed battery: Most generators have a battery in them in order to transfers power to a home’s electrical grid. Similar to a car battery, a generator battery can fail or lose its ability to hold a charge. Repair technicians can replace a failed battery and restore the generator.

Low coolant: In order to keep the generator from overheating while it works, some units use a coolant to lower internal temperatures. Coolant can leak, however. If you generator turns on, only to turn off again soon after, lost coolant may be responsible.


You must never try to repair a faulty generator on your own. In the first place, this can be dangerous if you lack the proper training and equipment. This is especially true of a generator that runs from natural gas.

As a general rule, no one except a licensed professional should repair a device connected to a gas line. Even if there were no safety risks involved, the complexity of a modern generator makes it very unlikely that you will locate the cause of the malfunction and manage a correct repair. Too much is riding on your generator’s operation: call professionals so the job gets done fast and gets done right.
