Honda EU3000is and Coleman A/C Won't Work

Now that's some problem solving if I ever saw any. lol

Comgrats on the new rig.

OK, I solved the problem. Traded the Jayco TT for a new Open Range 216RBS that has a 15K air conditioner and the Honda EU3000 runs it just fine. Kind of an extreme and expensive way to solve a simple problem but it works and I got 2 new slides to go with it. I also installed the Stromberg-Carlson A-frame generator rack. It's a great product and works just fine. Thanks to all for the input.

It's water under the bridge now, but the hard start kit is just a couple of capacitors. Generic kits work fine. All the A/C units I've seen already have connectors and places to strap the capacitors in. I know 20 bucks is 20 bucks, but I wish A/C units would come with them installed. Units would last longer if they did.

First step is the hard start capacitor. On order should be here in a few days.

I also found some reference to these units "short cycling" and not staying off long enough to pressure equalize. A delay cycle timer will be step 2 if the capacitor doesn't work.

Thanks for the input. I'll post what happens.

Well Wait a minute. Is the compressor already running at the 7-10 min point or has it cycled off (normal) and is it tripping when it restarts (Fan on all the time, compressor cycling). These are two vastly different conditions, and knowing which will probably provide the correct answer.

The Hard start kit will probably work if it is at compressor startup once it has run already, so long as the delay is correct. If it is tripping when the compressor is already running, then there is an issue with the steady current draw and the curve of the breaker, and probably some wiring issues.

Perhaps the contactor is flakey and intermittently dropping out, with the compressor trying to restart too soon...

The OP is not complaining, he is asking for someone with the same setup to chime in. Unfortunately it may be a rare combination so I am trying to help a bit here.

Why these asshats who manufacture these things don't start making Inverter style units is beyond me...

I'd suggest to install the Supco capacitor mentioned and also pull the cover of the A/C and make sure everything is clean and operating correctly.

I wouldn't discount the troubleshooting advice offered here. There may be something intrinsically wrong or unusual with YOUR Coleman Mach, connections, or use and that would be observed by measuring the draw of the unit. I know that sometimes we reach for the most reasonable matching circumstances when Internet mining for a solution. Unfortunately, that can sometimes lead down a path that wastes time or money and doesn't offer the correct solution.

Here's another thread I found of others having the same issue. Can't really explain the delay to overload but I'm not the only one experiencing it with this combo.

Post #22 may provide a clue. It seems this particular A/C may draw starting current for minutes instead of just seconds as most on here are assuming.

I'm not complaining. It's just that their guessing is not what I'm looking for. No troubleshooting, voltage checking or amp measurement is necessary. I'm looking for someone who has had and solved this issue with this particular combo of air conditioner and generator. The response from soundguy is probably the answer but I was looking for some confirmation. Don't really need troubleshooting tips but thanks anyway.
