Generator problems, need help.

I start the generator on my 2014 Coachmen Leprechaun every trip regardless of whether it's used or not. The last time it was started was in May and it ran for probably 10 minutes. A couple weeks ago, I took it out for the weekend and it absolutely won't not start. I got it to start a couple times but it just sputtered for a few seconds and died. It acts like it's not getting fuel. The status light flashes 3 times which apparently means get "service". I checked the oil and it was fine. I can't believe this practically brand new motorhome is already having generator problems. Any suggestions on things to try? Thanks.

Old gas? Needs to be run for several hours under load at least every 6 weeks. Check the level of the gas in the tank. Gas level should be at least 1/4 full to run.

Yeah, I thought maybe gas level too but I attempted with 3/4 tank and still no go. I've only run it once for several hours under a load while on the road once. If I can get it started again I'll be more diligent about doing that.

Per the Handbook....

Exercising Your Generator
It may seem surprising that “not” using a machine could cause performance
problems, but with RV generators that’s exactly the case. Regular “exercise” is
an important part of keeping your generator healthy. Lack of exercise can cause
moisture build-up and fuel system degradation that make it run poorly. In fact,
in as little as 30 days, the fuel in gasoline-powered generators can begin to gum
and varnish the fuel system. Fuel varnishing results in hard starting and surging. (A
surging generator never settles at a stable operating speed.)
To prevent such problems, it is recommended to run gasoline generators at a
minimum of 50 percent capacity (2000-watts, or one air conditioner for a 4000-watt
set) for two hours once every four weeks. This is necessary to help keep moving
parts lubricated, expel moisture and control fuel varnishing in the carburetor. A long
two-hour exercise period is preferable to several short periods. While traveling, this
can be accomplished by running the air conditioning.

Make sure they have not pinched the line coming from the tank to the generator, mine had the same problem took it into O/Cummings, ran their test and told me it was after the generator. Got under the Coach and found where the line was pulled over the frame and attached it had pinched the line enough to stop the flow from the Generator except for minimal fuel to start. We undid the line and gave it some play and attached it again and she started right up with no problem. 2015 28DS Coachman

If it come down to the carburetor they will tell you it is not serviceable. Then tell you $500 or more to replace. That's bull. A few hand tools including needle nose and 11/16 box and end wrenches and you can get the float bowl apart. Careful of small pieces and or springs. Compressed air, carb cleaner and some work can do wonders. One of my projects. Turned out no line filter on line from tank and all sorts of junk clogging the float bowl

I put a few drops of gas directly in the carburetor and the generator started tight up. After that, I ran it more often. Still starts fine, just needed a little boost.

Carb cleaner

Spray carb cleaner does miracles.
I have taken my carbs apart and cleaned them out on all my stuff successfully also.
My contribution to the conversation is I had all these problems go away when I switched to pure 100% gasoline without alcohol and use marine blue sta-bil.
For the last 5 years I have no trouble and don't wear the heck out of my Genie just to clean out the carb and innards by starting it all the time.

That is discouraging. Guess I will have to check mine to see if I need to add a filter.

Try starting it from the panel on the generator. Hold the prime button until the fuel line doesn't shake. It may take several minutes. You may have a lot of air in the line and just not getting past it.
