Generac Generator Troubleshooting
Generac generators are designed to provide reliable power in emergency situations or remote locations. However, if your generator isn’t working correctly, it can be frustrating and even dangerous.
Before you call a professional, it’s essential to troubleshoot the problem to determine if it’s something you can fix on your own.
In this article, we’ll guide you through the most common Generac generator issues and offer solutions to get your generator back up and running.
Generator Won’t Start
If your Generac generator won’t start, there are several potential causes to consider:
Battery Issues
If your generator has an electric starter, the battery might be dead. Check the battery terminals and cables to ensure they are clean and secure. If the battery is dead, you may need to replace it.
Fuel Issues
Generators need fuel to operate, so if the fuel tank is empty or the fuel is stale, your generator won’t start.
Check the fuel level and make sure the fuel is fresh. If the fuel is old, drain the tank and replace it with fresh fuel.
Spark Plug Issues
A dirty or damaged spark plug can prevent your generator from starting. Check the spark plug and clean or replace it if necessary.
Low Oil Pressure
Generac generators have an oil pressure switch that prevents the engine from starting if the oil pressure is low.
Check the oil level and add oil if necessary. If the oil level is correct, the oil pressure switch may be faulty and need to be replaced.
Generator Shuts Down During Operation
If your generator shuts down while in operation, there could be several possible causes:
Overload
Generac generators have a safety feature that shuts the generator down if it is overloaded. Check to make sure you’re not running too many appliances or devices that exceed the generator’s capacity.
Low Oil Pressure
If the oil pressure drops below a safe level while the generator is running, the generator will shut down automatically.
Check the oil level and add oil if necessary. If the oil level is correct, the oil pressure switch may be faulty and need to be replaced.
Dirty Air Filter
A dirty air filter can reduce airflow to the engine and cause it to shut down. Check the air filter and clean or replace it if necessary.
Generator Has No Power Output
If your generator isn’t producing any power, there could be several possible causes:
Faulty Voltage Regulator
The voltage regulator regulates the amount of voltage produced by the generator. If it’s faulty, the generator may not produce any power. Check the voltage regulator and replace it if necessary.
Broken Alternator
If the generator engine is running, but it still does not produce any power, then the alternator may be broken.
The alternator is responsible for generating the electrical power in the generator. If it is broken, it needs to be replaced.
You can test the alternator by using a multimeter to measure the voltage output. If the voltage reading is zero, then the alternator is likely broken and needs to be replaced.
Damaged Wiring
If the wiring that connects the generator to your appliances is damaged or disconnected, your generator won’t produce any power. Check the wiring and repair or replace it if necessary.
Generac Propane Generator Troubleshooting
Here are some troubleshooting tips for Generac propane generators:
- Engine fails to start: check fuel pressure, fuel supply, and spark plug.
- Low power output: Check fuel supply and air filter.
- Engine shuts off: Check low oil pressure, clogged air filter, and fuel supply.
