Troubleshooting
5Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Generator Set does not start | Fault Warning or Shutdown | Check the fault warning and reset the controller if necessary |
| Engine fails to reach operating temperature | Cooling system issue | Check coolant level, flush and clean cooling system if necessary |
| Generator produces insufficient power | Air filter clogged | Clean or replace air filter |
| Gas fuel leaks can cause an explosion. | Check the LPG vapor or natural gas fuel system for leakage by using a soap and water solution with the fuel system test pressurized to 6--8 ounces per square inch (10--14 inches water column). Do not use a soap solution containing either ammonia or chlorine because both prevent bubble formation. A successful test depends on the ability of the solution to bubble. | |
| LPG liquid withdrawal fuel leaks can cause an explosion. | Check the LPG liquid withdrawal fuel system for leakage by using a soap and water solution with the fuel system test pressurized to at least 90 psi (621 kPa). Do not use a soap solution containing either ammonia or chlorine because both prevent bubble formation. A successful test depends on the ability of the solution to bubble. |
