How to fix a DuroStar Portable Generator that will not start?

  If your DuroStar Portable Generator's engine won't start, several factors could be at play. First, ensure the engine switch is set to the “ON” position. Next, verify that the fuel valve is in the “OPEN” position. Also, make sure the choke is closed. Check the fuel level; if it’s low, add gas, or if the gas is old or contaminated, replace it. Inspect the spark plug for dirt and clean it, or replace it if broken. Ensure the generator is on a level surface to prevent the low oil shutdown from activating. Finally, check the oil level and add or replace oil if necessary.

What to do if my DuroStar Portable Generator runs but has no electrical output?

  If your DuroStar Portable Generator runs but provides no electrical output, check if the circuit breaker is off and set it to the “ON” position. If you're using an extension cord, try a different one. Also, the connected electrical device may be faulty, so try connecting a different device to see if that resolves the issue.

Why my DuroStar DS4400 runs but does not support all electrical devices connected?
- M
  Maurice BeckerAug 16, 2025
  If your DuroStar Portable Generator runs but cannot support all connected electrical devices, the generator might be overloaded; try connecting fewer devices. A short circuit in one of the connected devices could also be the problem; try disconnecting any faulty or short-circuited electrical loads. Additionally, a dirty air cleaner can cause this issue, so clean or replace the air cleaner.
