Yamaha 2400 owners?

[wantostream]

Hello and Happy New Year to all !!!
I have gone through the various threads concerning portable generators but wanted to know from owners of Yamaha 2400's if indeed it will run a 13,500 btu A/C. If so does it sound like its maxed out roaring like it would blow up after awhile.
I will appreciate any feedback.

Thanks,

Cary

While at the 2008 Vintage Trailer Jam the Colin Iwasa from Yamaha USA ran my 15K BTU AC for over 45 minutes. I had the frig on gas and the 2 AGM batteries were charged (have solar). No other 110 volt AC devices were on. I ran the 19 LCD Sony TV via the inverter for 15 minutes while AC was on high fan speed and the compressor was on. After I shut the TV off, Colin asked me to have my wife plug in her hair dryer(2000 watt) and run it on low heat. She had it on for over 5 minutes. We switched it up to high heat the the breakers tripped on the generator and AS. We reset the breakers (AS and 2400) and waited 5 minutes before starting the 2400 and AC. The AC's compressor came on after about a minute and it continued to cool the camper. The 2400 never ran that loudly even with the hair dryer on low speed. The temperature was in the upper 80's and humidity was high.

Starts and runs the A/C with only initial small increase in rpms. Drops back and runs quiet and steady thereafter. Have'nt run other high current draw accessories concurrently, but handles small draw things such as lights comfortably.
A/C start-up will probably present the heavyiest load of all your standard trailer equipment. If you're running other electrics at time of start-up, you might want to let the A/C fan get up to speed before switching over to "cooling" to eliminate some of the initial load.
Biggest drawback is, the 2400 is; a bit heavy to carry. You might like to look into finding some wheels for it. Since my hard toneau cap does'nt open up fully, I roll mine to the back of the truck bed on a mechanic's creeper. Not the most elegant solution, but works for me (barely).

Hi, my trailer has the 11,000 BTU A/C and my generator runs the A/C and the refrigerator and the television with no problems. I keep my generator inside of my trailer when not using it. [no fumes] I can move it by myself, but since I have had some back problems, my wife insists on helping me move it. Good thing it has two handles. If we need to use the Micro-wave, I turn off the A/C until done cooking and turn the A/C back on. I chose this generator so I could have a reasonably light single generator that would run my A/C if needed.

When not in use, I use my generator as a Foot- Stool. Double duty.

My 2400 runs our 13,500 AC with no problems!

Same thing here, no problems and stays relatively quiet.

[TG2500]

My 2400 has run the ac (albeit so far for only short periods as we haven't had any long spell of hot weather yet) without any problems. Last night it went (cycling on & off) for 1.5 hours with no problems whatsoever.

On the subject of 2400's, what do you do when it rains out? Can the 2400 operate in the rain? Anything special you need to do for the control panel or plugging in the RV power cord/adapter?

our LP converted 2400 (USCARB) runs our 13.5k A/C

owners manual recommends keeping genny out of the elements

I have the 13.5 BTU AC and the 2400 runs it fine. I bought the 2400 not only for dry camping but also, in my hurricane prone area if I need temporary housing after a hurricane, I can use my trailer in my driveway and have AC. When camping I leave mine in the bed of my F250 and I have the Rollnlock retractable bed cover that covers it while traveling, raining, or just to keep out of sight. I leave it in the rear corner of the truck bed and when I use it I lower the tailgate, ensure the exhaust faces out, and connect the shorepower to it. Like said earlier, it is a little heavy, about 70 pounds but it works great. Starts on the first pull everytime! Quiet too!

Ditto. Plus I really appreciate the lack of maintenance having mine run on LP.

I just got my new EF2400IS with the tri-fuel option and IT WOULD NOT START THE AC unit (new 13,500 BTU "AirV" from Carrier, on a Sport 17).

The service rep at the local Airstream dealer called Carrier who says that the startup draw on the AC unit is 28-29 amps (about 3335 watts), and that's way more than the 2400 max that the Yamaha generator puts out.

What could be letting all you guys use this generator and not me?
What am i missing?

Thanks for any help you can offer.

I have had my 2400is for about 4 years and used on my old sob with a 13,500 Coleman AC and had no problems. I have also used it for a couple hours on my 15,000 Dometic AC on my AS. No problems at all as long as only using it for AC or anything else when the AC is not running.

Might check into the addition of a hard start kit on the AC. That'll beef up the start-up capacitor and smooth out the start-up spike.

What size breaker is the AC on? If it's on a 20A breaker you've got a chance. If it's using a 30A breaker you probably aren't going to get there.

[boondockdad]

your '09 should already have a start capacitor (though, some might argue the effectiveness of one, AOT a 5-2-1)
my 2400 will not start the a/c if:
- the converter/charger is attempting to bulk drained batteries
- any lights r on
- refrig is on "AC"

any other electrical draws... w/h, pump, etc....

also, the choke was mis-aligned from the factory- is the 2400 running rough? Do you have an RPM display?

[AirsDream]

... mine runs my a/c fine on gasoline or propane (haven't yet tried natural gas) but I "think" my a/c is only 11k btu. Just for fun and as a test, I ran it all one afternoon in 98 degree heat, and in full sun. Genny ran fine, a/c ran fine, coach was cool as could be. I'd too would end to suspect your a/c unit's compressor motor capacitor, or that there was other "stuff" running in the coach ...

According to the Carrier AirV specs, these units require a 20A circuit breaker -- unless I got the model wrong, I think the 28-29A quote is a tad off... The specs also indicate ~12.8-14.1 full-load amps.

Perhaps while on generator you can try starting with fan only, then once operating kick in the cooling mode at a higher temp, feathering it down to your desired setting once you know the compressor is doing its thing.

I found something like this technique in the troubleshooting section of the installation/owner's manual for the AirV. Might work for you.

Cheers,

Mine won't start my ac. The gen trips its overload switch.

I won't try it again.

It's on a 20 amp breaker...
Any details on this "hard start kit"?
I gotta try something, or else I'm out a lot of money for nothing!
Thanks for your help.

There was nothing else running on AC, as I turned off the other two 20 amp circuit breakers.

I did try turning the temp all the way to warmest setting, and still No Go.

Thanks for your help.
Still at a loss...

Thanks for the link, but that's the same one I got from the Airstream dealer, but the 12.8 amp figure is for after the unit has started, not under start-up load, and it figures out to 1472 watts at 115 volts. I can operate the microwave which uses 1450 watts, but not the AC. The Airstream dealer service tech got the 28-29 amp figure from Carrier, today.

I guess I'm puzzled that it draws 28 amps at startup but it's on a 20 amp circuit breaker...
