  If the remote start system on your Firman Portable Generator isn't working, the issue could stem from several causes. First, check the batteries in the remote control and replace them if they're low. You might also be exceeding the remote control's range, so move closer to the generator, ensuring you're no more than 164 feet away. Finally, the remote control may not be programmed to the generator; see 'Programming the Generator for Remote Start'.

  Stephanie HamptonAug 12, 2025
  If your Firman Portable Generator's engine runs but there's no AC output, it could be due to several reasons. First, check if the circuit breaker is open and reset it. If that's not the issue, there might be a fault in the generator itself, requiring you to contact an authorized service facility. Also, inspect for poor connections or a defective cord set and repair them. Finally, the connected device could be faulty, so try connecting another device in good condition.

What to do if my Firman Portable Generator bogs down under load?
- A
  Alan CabreraAug 20, 2025
  If your Firman Portable Generator runs well without a load but bogs down when loads are connected, several factors could be responsible. A short circuit in a connected load might be the issue, so disconnect any suspected electrical loads. The engine speed could be too slow, requiring you to contact an authorized service facility. The generator might be overloaded, so avoid overloading it. There could be a shorted generator circuit, which also requires contacting an authorized service facility. Lastly, a clogged or dirty fuel filter can cause this, so clean or replace it.

Why does my Firman Portable Generator shut down while running?
- L
  Lisa LoweAug 25, 2025
  If your Firman Portable Generator shuts down while running, common causes include running out of fuel, a dirty air cleaner, or low oil level. Ensure the fuel tank is full. Clean or replace the air cleaner. Check the oil level and fill the crankcase to the proper level, or place the generator on a level surface.
