  Lisa DuncanAug 4, 2025
  If your Wen Portable Generator runs but doesn't provide electrical output, the circuit breaker may have tripped due to an overload. Turn off and unplug all connected electrical devices. After waiting 5 minutes, reset the circuit breaker. Check the total wattage of the devices to ensure it doesn't exceed the generator's capacity. Plug the devices back in one by one. Also, inspect the power and extension cords for damage and replace them if necessary. Try connecting a different device to rule out issues with the original device.

  If your Wen Portable Generator runs but doesn't support all connected devices, it might be overloaded. Turn off and unplug all electrical devices, wait 5 minutes, and then press the circuit breaker to reset it. Reduce the load by using fewer devices simultaneously. Another possible cause is a short circuit in one of the devices. Try disconnecting any potentially faulty electrical loads. Also, a dirty air filter can cause this issue, so clean or replace the air filter element.

How to fix a Wen 56155 that will not start?

  Willie ThompsonAug 18, 2025
  If your Wen Portable Generator engine won't start, make sure the engine switch is set to ON and the fuel valve is also set to ON. Check the oil level and add or replace oil if it's low. Ensure the engine has fuel and that it's fresh, not contaminated or old. If the spark plug is dirty or broken, clean or replace it. Also, the carburetor might be air locked. To resolve this, shut off the fuel valve, remove the bolt from the bottom of the carburetor, take off the carburetor bowl to allow it to reset, then replace the bowl and reinstall the bolt.

Why is my Wen 56155 Portable Generator engine RPM fluctuating?
- L
  Larry Burns Jr.Aug 27, 2025
  If your Wen Portable Generator engine is 'hunting' (RPM fluctuating), the fuel may not be running through the fuel valve properly. Turn off the generator and wait for it to cool down, then check the fuel valve. Also, the air filter could be clogged, so inspect and clean it as needed. A blocked muffler or spark arrester can also cause this, so check the spark arrester and clean it with a metal brush if necessary. Gunk in the carburetor preventing a consistent fuel/air mixture can also be the reason. Use 'gunk remover' spray on the carburetor jets.
