How to Troubleshoot Generator Problems Like a Pro

Generators help when the power grid fails or it isn’t available, such as during a blackout or an outdoor event. Every generator brand is susceptible to breakdowns or wear and tear, but there may be simple fixes. Regularly check your generator and look for common issues you can quickly troubleshoot.

Empty Fuel Tank

When your generator doesn’t start, a million possible reasons may run through your mind. The first place to look is the fuel tank because the generator won’t run if that’s empty. Add gasoline and try starting it again, but make sure not to use stale gasoline that could cause clogs.

Low Oil Level

The oil keeps the parts of your generator lubricated and working smoothly. The right amount of clean oil keeps the performance at its peak, and using the manufacturer’s recommended oil improves the service life. Use a dipstick to check the oil level and keep your generator on a flat surface.

Battery Failure

Another common generator problem is a battery issue, but it’s usually from human error. It could be from shutting down the electrical board to work on it, but you can check the circuit breaker to see if it is off. The generator should turn on after flipping the slot on, or it could be another issue.

The problem could be dirty connectors if the electrical board is still on but won’t start. Debris may be sticking to the battery terminals and preventing a strong connection with the generator. If the terminal connections aren’t dirty or loose, you may have to buy a new battery.

Coolant Leaks

Coolant hoses are prone to leaks due to the excessive temperatures of generators. Cooling maintenance isn’t complex in generators, but you should check hoses at least once a year.

During cooling maintenance, check for visible damage and determine if hoses are structurally sound. To prevent system failure, replace the hoses if you notice wear and tear. To keep your generator running smoothly, flush the old coolant and replace it after checking or replacing the hoses.

Dirty Air Filters

Generators need air filters to block debris, but a dirty filter won’t let your generator run efficiently. Leaving a dirty filter in your generator can shorten its life span, so inspect this every few months to keep everything working. Most air filters last two or three months, but you could get a reusable one you can clean.

Spark Plug Issues

Spark plugs break down from wear and tear over time, and there are several reasons why they stop working. An ignition spark tester can check if there’s an electrical current reaching the spark plug. Clean them if there’s carbon buildup, but you need to replace damaged spark plugs.

Generators help during emergencies or outside events but are susceptible to malfunctions. Troubleshooting low oil levels to leaking coolant is a good way to keep everything running. If you require generator service in Memphis, TN, call us at Rush Electric today.
