If your generator won\u2019t start, then you may be stuck without electricity in an emergency. Corbin Electrical Services, Inc. performs generator repairs across all of New Jersey. In this blog post, we discuss how to troubleshoot your generator and when to call our electricians.Key TakeawaysNever ignore a generator that won\u2019t start. Delaying repairs can leave you without power during an emergency, so you shouldn\u2019t put off a response.Troubleshoot your generator by checking the battery, oil level, fuel level, filters, and control panel. Some issues can be resolved with a quick recharge or refuel.If basic troubleshooting doesn\u2019t find the problem, or if the control panel shows a maintenance alert, then contact an electrician for professional repairs.Routine maintenance can prevent generator shutdowns by diagnosing and repairing issues early, giving you peace of mind that your equipment will work when you need it.Why Won\u2019t My Generator Start?If your generator won\u2019t start, then don\u2019t ignore the problem. If you put off repairs, then you risk leaving yourself without electricity in a storm, heatwave, or other emergency situation. Instead, start by troubleshooting. Here are some common generator issues to check for:Dead battery: Most generators require a small amount of charge to get started. If the battery is dead or weak, then your equipment may lack the power to produce a spark.Low oil: Generators need oil lubrication to prevent friction. Many generators have a safety sensor that stops them from starting if oil levels are low.Insufficient or stale fuel: Check the fuel level to make sure the tank has enough gas to run. Remember that if you have a gasoline-powered generator, stale fuel can cause starting problems. If the gas is more than a few weeks old, replace it.Dirty filter: Clogged components can block airflow to the generator, keeping it from starting. Check the filter and clean it if it looks soiled.Control panel fault: Make sure that the fuel valve is turned to the open position, that the main engine and fuel switches are flipped to on, and the choke is set to full.In most cases, the malfunction is caused by one of the above issues. These are all issues that can be checked and typically addressed by a homeowner. By recharging the battery, refilling oil or fuel, or cleaning the filter, you can usually get your generator working again.When Should You Call an Electrician?If basic troubleshooting does not identify the issue, or if the control panel shows a maintenance alert, then it\u2019s time to call an electrician.
