  If your TPE Inverter's engine runs but provides no electrical output, try these steps: * First, reset the reset breaker and thermal breakers. * Check that the power cord plug is fully engaged in the inverter's outlet. * If the issue persists, the power cord may be faulty and need replacement. Try a known good appliance to check if the inverter is producing power. If none of these steps work, the inverter might have an internal fault and needs servicing by an authorized dealer.

  If your TPE Inverter engine won't start or stay running, consider the following: 1. Ensure the inverter has gasoline. Add gasoline if necessary. 2. Inspect and clean fuel delivery passages, and verify the fuel shutoff is in the ON position. 3. Check and clean the air filter. 4. Check the oil level and add oil if needed, as a low oil level can prevent starting. 5. Make sure the spark plug boot is fully engaged with the spark plug tip. 6. Remove and inspect the spark plug; replace it if faulty. 7. Inspect and clean the spark arrestor. 8. Drain stale fuel and replace it with fresh fuel. If these steps do not resolve the issue, the ignition coil or start switch may be faulty, requiring service by an authorized dealer.
