Experiencing issues with a generator that starts but won’t stay running can be frustrating. Whether you’re dealing with a brand new generator or an older one, several factors can contribute to this problem.
From fuel-related issues to mechanical malfunctions, understanding the possible causes and solutions is essential to keep your generator running smoothly when you need it most.
Why Won’t Your Generator Stay Running?
New Generator Setup
If you’re encountering this problem with a new generator, it’s important to ensure that you’ve properly set it up. New generators often require a specific start-up procedure to ensure they operate smoothly:
- Add Oil: Check and fill the oil reservoir to the recommended level;
- Add Gasoline: Fill the fuel tank with the appropriate gasoline;
- Turn Breaker Off: Make sure the circuit breaker is in the off position;
- Turn Gas Valve On: Open the gas valve to allow fuel flow;
- Close Choke: Adjust the choke to the closed position;
- Start Generator: Initiate the generator’s starting process;
- Open Choke: Gradually open the choke as the generator warms up;
- Turn Breaker On: Activate the circuit breaker;
- Connect Equipment: Plug in your devices and equipment.
Missing any of these steps can lead to your generator shutting down or overheating.
Old Generator Troubleshooting
For older generators, especially those with stale fuel inside, troubleshooting becomes more critical:
- Clean Carburetor: A clogged carburetor due to old fuel can cause shutdowns. Using a carburetor cleaner or consider professional servicing;
- Check Fuel System: Clean the fuel tank, fuel lines, and replace the fuel filter if needed;
- Inspect Air Filter: A dirty air filter can affect air intake, leading to shutdowns. Clean or replace it;
- Oil and Coolant Levels: Ensure proper oil and coolant levels and pressure;
- Visual Inspection: Look for frayed wires, worn-out connections, and leaks;
- Battery Check: Check the battery for full charge and no corrosion.
Common Causes and Solutions
Fuel Delivery and Air Flow Issues
- Clogged Carburetor: Old fuel can clog the carburetor. Clean it with a carburetor cleaner or have it professionally rebuilt or replaced;
- Clogged Fuel Filter: Replace a clogged fuel filter to ensure proper fuel delivery;
- Fuel Valve Blockage: Ensure the fuel valve is open to allow fuel flow. Replace a clogged fuel valve if needed;
- Air Filter Blockage: A dirty air filter restricts air intake. Clean or replace it to improve air flow.
Cooling System and Electrical Problems
- Cooling System Maintenance: Regularly clean air intake and cooling fins to prevent overheating;
- Electrical Issues: Faulty wiring or battery connections can disrupt ignition and operation. Consult a professional for proper diagnosis and repair.
Overload Problems
Exceeding Capacity. Overloading your generator can trigger the circuit breaker and cause shutdowns. Calculate the load and prioritize essential devices.
