    What to do if my Firman Portable Generator has no AC output?
    • G
      gonzalezpeterAug 1, 2025
      If your Firman Portable Generator's engine is running but there's no AC output, first, reset the circuit breaker. If that doesn't work, check and repair any poor connections or defective cord sets. Try connecting another device that is in good condition. If the issue persists, it may be a fault in the generator, and you should contact an authorized service facility.

    Why does my Firman Portable Generator bog down under load?
    • S
      scott72Aug 6, 2025
      If your Firman Portable Generator engine runs well without a load but bogs down when you connect loads, there might be a short circuit in a connected load, so disconnect it. Also, the generator may be overloaded. Another possibility is a clogged or dirty fuel filter, which you should clean or replace. If none of these actions resolve the issue, it may be due to engine speed being too slow or a shorted generator circuit, in which case you should contact an authorized service facility.

Check the oil level and fill the crankcase to the proper level, or place the generator on a level surface. Clean or replace the air cleaner, and make sure you have fuel in the tank—if the fuel is stale, drain the tank and carburetor and refill with fresh fuel. Also, ensure the spark plug wire is connected, and replace the spark plug if it's bad.
