You never know when the next blackout is going to occur. So, when something is wrong with your commercial generator, you need a team of professionals to address the problem as soon as possible. The Mr. Electric of Chapel Hill electricians can help you fix any problem with your generator. Some of the most common issues we see in backup generators include:

• Battery Failure – Just like your car, many generators rely on a battery to start. This is the most common problem with generators. Sulfate build-up, open cells, shorts, and poor connections can cause your battery to fail to start your generator.
• Faulty Block Heater – When a block heater runs often enough, it can malfunction and set off the low coolant temperature alarm.
• Low Coolant – Without coolant, your generator will begin to overheat and shut down automatically. Sometimes, a low coolant problem is related to clogged radiators or leaks.
• Wet Stacking – Wet stacking occurs when unused fuel passes through your generator and accumulates in your exhaust.
• Air in the Fuel System – When a generator is left dormant for a while, air can get into the fuel lines. This may prevent the injectors from firing.
• Controls Are Not on “Auto” – If your generator is not set to “Auto,” it may act as the main control switch and may not turn on/off when it should.
• Out of Fuel – If your generator does not have enough fuel, it will shut down on its own.
• Tripped Breakers – The power to your generator may be interrupted if the emergency shut-off or automatic transfer switch has been flipped. Using the automatic transfer switch is unsafe if you have not been taught how to do so.
