  If your Wen Portable Generator runs but provides no electrical output, start by turning off and unplugging all electrical devices. Check the reset button; if it has activated due to wattage overload, press it to reset. Also, check the breaker; if it has tripped due to wattage overload, wait 3 minutes and press the activated breaker to reset. Make sure to check the total wattage of the devices and reduce the load if it exceeds the generator's capacity. Inspect power and extension cords for damage, replacing any damaged cords immediately. Finally, try connecting a different electrical device to rule out a faulty device.

Why is the engine RPM fluctuating on my Wen Portable Generator?
- J
  James RobertsAug 7, 2025
  If your Wen Portable Generator's engine RPM is fluctuating, it could be due to several reasons. First, make sure there is enough fuel and that the 2-in-1 switch is turned to RUN. If you're using propane, the level might be getting low, so switch to a new propane tank or use gasoline. A dirty air filter or spark arrestor can also cause this issue, so clean or replace them. Additionally, gunk in the carburetor can prevent a consistent fuel/air mixture; use carburetor cleaner spray on the carburetor bowl and jets to resolve this.

How to fix a Wen Portable Generator that runs but doesn't support all connected devices?

  Margaret SmithAug 12, 2025
  If your Wen Portable Generator runs but doesn't support all connected electrical devices, it could be due to overloaded AC or DC receptacles, which can cause the circuit breaker to trip. To fix this, turn off and unplug all electrical devices, wait 3 minutes, and then press the breaker to reset it. Also, check the amperage of the devices to ensure they are within the receptacles’ rated capacities. A short circuit in one of the devices could also be the cause, so disconnect any faulty or short-circuited electrical devices. Lastly, a dirty air filter can contribute to this issue, so clean or replace the air filter element.
