Why DUROMAX Portable Generator engine will not start?
- A
  Angelica PerkinsJul 29, 2025
  If your DUROMAX Portable Generator's engine won't start, several factors could be at play. It could be something as simple as the engine switch being in the “Off” position, in which case you should set it to “On”. Alternatively, the fuel valve might be “Closed”; turn it to “Open”. Other potential causes include an open choke (close the choke), an empty fuel tank (add fuel), old or contaminated fuel (change fuel), a dirty spark plug (clean it), a broken spark plug (replace it), the generator not being level (move it to a level surface), or low oil (add/change the oil).

  If your DUROMAX Portable Generator runs but provides no electrical output, the issue might be a circuit breaker that is “Off” (turn it “On”). Another cause may be a bad wiring connection, so replace the extension cord(s). Lastly, the device connected to the generator could be malfunctioning, so disconnect it.

  If your DUROMAX Portable Generator runs but can't support all connected devices, it might be overloaded. Disconnect one or more items to reduce the load. A malfunctioning device connected to the generator could also be the problem; disconnect it. Lastly, check if the air filter is dirty and clean or replace it.
