I've just been noticing...In my Sanibel, the AC fan comes on first, and then about 15 seconds later, the compressor comes on. At least they're not starting at the same time. Still not as good as Turbs mod since in my case, the fan current is there when the high compressor startup current is present.

Hello
I have a work around that has worked for me. I have also installed the hard start kit.
Turn Refrig. On gas
Turn breaker off to converter
Water heater to gas
Now start A/C, after complete unit is running turn breaker back on to converter.
This allows all power from gen. To start a/c.

My system was a 15K a/c w/ Honda 3K gen.(EU series)

I always get the AC fan up to speed before starting the compressor when running on the genny. Not sure, but cutting on the fan beforehand may also help energize the start capacitor.

I've ordered the parts for both the hard start kit and the fan delay-on-start mods.

I'm going to do one more mod in addition to that, that is adding a off-delay timer to the fan.

When the compressor shuts down, there is still cold air that can be delivered out of the cooling coil and ducting. Delaying the fan shut down by 1 to 2 minutes allows you to recover that cool air. It's also helpful in circulating the air in the RV.

I've done this same mod in my S&B, and it really has helped.

All that is required is an ICM203 DOB (Delay On Break) relay, and wire it in the wire from the thermostat after the ICM102 DOM(Delay On Make) relay. Easy mod to make.

My Dometic thermostat does that already. Maybe it's a setting in yours? (I know it's a setting in my home thermostat.)

Your doing what the relay does but manually.
But on cooler days where the a/c kicks on and off that would be no fun lol .
Unless of course you leave the fan to the "on" position.

We have a Surveyor Select 264 with one 13,500 BTU AC unit. We wanted a generator to power the AC and also charge our two batteries when we wilderness camp.
We need battery power to run the fridge.

Looking at all of the generators, we decided on a Yamaha 2400 because of the following reasons.
1. The Yamaha web site says this model will power most 13,500 BTU RV air conditioners.
2. The generator is fairly light weight, only 75 Lbs. dry.
3. The generator is quiet, only 53 to 60 dBA.

Well brand new camper, brand new generator and NO AC.
Ya the generator will not run the AC.

Installed a SUPCO SPP SUPER BOOST AC hard start kit. Cost about $10, took less than 30 minutes to install.
Now I have AC.

This may also work if you are trying to run your AC with a 2000 watt generator.
I know some people that do.

GeoFish

I have this gen and it runs my 13.5 Coleman Mach....Without any mods such as a hard start. Never used it in anything over 90F so this may be the differance. Love it becasue it will run for almost 9 hours on about 1.5 gallons of gas and you can load it with one person. I run the fan for a few minutes prior to turning the a/c on. This seemd to work for me.

Yeah, I just leave the fan on when using the AC, even when on the grid.
