Common symptoms
- Nothing happens when you press the start switch
- It cranks but never fires
- It starts, then dies as soon as you release the switch
- It starts from the generator compartment but not from inside the coach
- A fault code or blinking light appears on the control panel
Possible causes
- Weak or disconnected house/start battery
- Fuel level too low — many coaches shut off generator fuel before the tank is empty
- Stale fuel or varnish in the carburetor after long storage
- Low oil level
- Tripped breaker, blown fuse, or loose connection
- Fuel pump, ignition, or control board issues
Safe things you can check
- Make sure you have at least a quarter tank of fuel or propane, as applicable
- Check the battery charge and that the battery disconnect is on
- Check the oil level per your generator manual
- Try starting at the generator itself to rule out the remote switch
- Write down any blinking fault code — your manual usually explains it
When professional repair makes sense
If the basics check out and it still won't start, it's time to call. Don't work on propane lines, fuel pumps, or the generator's control wiring yourself. RV generators share space with fuel and living areas, so leaks and wiring faults are a safety concern — and always keep your CO detector working.
