My XP2000 watts DuroMax sidekick starts and runs it just fine. Only 4 wires to hook up and mine came with all of the necessary connectors and splices and even a bit of extra wire. It only took 20 mins to hook it up. You need to follow the instructions. The last step is  for the Easy Start to learn the start up. Start the ac with house hold current the first five times waiting 5 mins between each start. Then you can use your generator. If you use a meter to check the draw of current each time, you see the last one is a lot lower and when you use the generator you will see a hugh difference.
You will love it.

Thanks Jack!  Good to know!  Got a link for the setup you are using?  We have an almost new Honda 2200i and it would be nice to be able to run the AC if the power ever goes out here (the onboard propane generator uses WAY too much propane...probably the most inefficient generator ever!).

Sounds like a pretty good idea!  Does that mean that the little Honda 2200 inverter generators should be able to start and nun now on that device?

Daniel, I just installed a Easy Start from Micro Air on my rv ac and it reduced the start up amps from 45 amps to 13 amps. I did this so that I can run my ac on my 2000 watt inverter generator. Have you thought of that?

I ordered a new hard start capacitor to deal with any issues with blowing breakers or fuzes on start up. Didn't realize it was an issue.

If it ain't broke, don't fix it. That's what I like to say as well.

 Maintenance will never go away though.

Glad you got it going. We have been in the low 90's here in the Cleveland Ohio area. My house central air is working good. I had to replace the sticking compressor relay 2 years ago. So far working great again.

So here is a little update on the air conditioner.

I'm still waiting for the capacitors and the relay to arrive...but for now it seems to be working just fine again.  When I went to get the part numbers off the capacitors and relay, the relay was covered with old mud dauber I had to tap on the nests and break/scrape them off.  And I think that freed up the relay.  Either that, or there was a bad wire connection, and removing/reinstalling the wires on everything corrected the problem.  I'm going to leave well enough alone and just keep the parts as spares and use them if I need them...but for now?  If it ain't broke, don't fix it.

I also managed to install a new and proper 30 amp power cord and outlet and outlet box to plug the coach into, since the previous owner simply buried an RV extension cord to get power to the coach.  So now the RV is on a good power source with a brand new breaker.  Because that other cord was there on its own breaker, I decided to run a cable from the generator compartment and tie it in to the cable that goes into the coach to power the rear air conditioner when the generator is running...and put a 30 amp plug end on the other side, plugging it into the old plug coming out of the ground.  So now I can also run the rear AC on really hot days, and it is running off its own breaker!  SWEET!!!

And I also designed and hooked up a hard PVC sewer line to the coach which works perfectly and eliminated the fly problem we were getting around our flexible sewer hoses...apparently flies can smell right through those thin flexible hoses.

I'll post some pictures when I get a chance.

Hi Kevin. Compressor relay or contactor sticking on.

Comment by Kevin F Smith on July 5, 2020 at 10:40am

So I called Camping World, and they were no help, even though I gave them the exact model of AC unit we have, a Coleman SuperMach 6799-807. Coleman is closed for the weekend, so back up on the roof I went! I removed the shroud and the plate that holds the capacitors, and thankfully all three (yes, there are three of them on our unit) were still legible on the sides. So I ordered three new capacitors with the exact same specs from Amazon, and they should be here in a couple of days. I also ordered a Coleman AC relay from Amazon that should be here in less than a week. The relay wasn't marked, so I guessed a exact replacement with the exact positions of the terminals wasn't something I could find, but this one does say Coleman, etc, and the terminals are numbered the same. Hopefully it is just one or more capacitor, which I will replace as soon as all three get here. They were cheap. If that fixes it, I'll return the 30.00 relay and get my money back...or use it if I have to. I'll let you all know if it fixes the problem!
