Honda EU2000i or A/C issue. Help

For troubleshooting purposes, try running a microwave oven or portable electric heater and see if the honda can run them. We need to determine if it is the generator or the a/c unit thats having a problem with a heavy load.

Hi Tim,

I sugest that you try adding a Supco SPP6 hard start capacitor. The cost about $15 and installation is simple.

I actually used the SPP6E. One other thing to remember is that the newer A/C units use less electricity. When I was doing this mod I found that the Dometic 13.5's made in the last few years use a couple of amps less than the ones made 10+ years ago. Even so, the SPP6/E solution should help you. Here are some instructions I found Mod My RV SPP6

If you are adding a hardstart to your RV A/C unit, use the SPP6 (no E). The SPP6E is not designed for 120VAC applications, The “E” series is also an instant restart unit, this does not allow the generator sufficient time to rampup to full power. The SPP6 has the preferred PTC relay and allows a longer ramp up time. The SPP6 is rated for 120VAC usage.
Remember for every thousand feet above sea level you generator drops 3% of output. On hotter days the A/C drops in efficiency as well. Check with your A/C manufacturer on the correct generator size for your unit. As far as I know there is not a manufacturer that will reccomend a 2000 watt generator to run a 13,500 BTU A/C unit.
If you have any questions about the SPP6 or any other Supco part, please contact us at 1-800-333-9125 ext. 261 our Tech Support will be glad to assist you.

Sorry, I was wrong. I did indeed use the SPP6. I had to look back at my order history.

I did use the SPP6. But I also noticed that my A/C unit already had a start capacitor on it from the factory. I just added the SPP6 in addition. Do I need to remove the factory start capacitor?

I would be grateful if someone could check the max startup amps on there 9200 btu Polar Cub and let me know what it is so I know if mine is working properly. No one or specs don't show what the max startup amp draw is, only the running amp draw. My running amp draw is 7.1 amps but max startup is 23.1.

Thanks for the help guys. I'm not giving up yet. I'm going to do some more testing tomorrow and possibly get a different generator.

Back to the original topic, as I wrote last night I install a Supco Hard Start Cap. and that didn't work either. So today I spoke with one of my A/C subcontractors about the issues I am having. I'm a Residental General Contractor. Anyway they suggested to check amp draw when starting the A/C on shore power and to check the voltage drop on the generator. I did both and found some interesting info. Attached to shore with all appliances off the amp reading was .03. With the A/C fan only running the amp draw was 1.7. The max amp draw with the A/C starting was 23.1 amps. Then maintained 7.1 amps.
So then came the voltage drop from the generator. With the generator running (not on Eco) voltage was 127 volts, upon A/C start up voltage dropped to 65v, then 30v, then 15v, then 3v, then the generator died.
If this is the norm I don't know how anyone gets by with this generator.
Now maybe there's something wrong with A/C causeing such a amp draw, I don't know. Now keep in mind this a 2007 Polar Cub. The previous owner said he never used the A/C because they live in Denver and always camped in the mountains.
I did reconfirm with Bob at Outfitter today that this is a 9200 btu unit. He recommend taking the generator back and trying another one. I may do that tomorrow.
If anyone has run across this issue and has had success with a cure let me now.

Thanks Tim.

Also the mach 8 cub is r410a ref too
The reson I got from the tech for the higher numbers is since the r410a was used in 09-10 is its harder to pump thru the system causing a more powerfull compressor

The mach 1 ps # is 48207c966 , its interesting that the get those lower #`s and it dosent have a soft start cap on it only a run cap
I wiil be getting one of those before the summer 2014, unless some one has a good older polar cub to sell , ha ha

Reddog the 47201a876 is the new mach 8 cub , not in stores yet
the 49201a876 is the polar cub with r 410 a refrig , there are a few other previous versions , been made since 2009 or 10 ,the data sheet for it shows 11.5 amps , the 9000 series was made prior to that. The reason it says to use the mach 8 cub is because thats what their making or about to make , the main mach 8 page hasent caught up yet , I waited quite a while for them to post the new mach 1 power saver which is the closest thing they make to the polar cub as far as amp draw 9.5, watts in normal 1025 and desert 1260 , locked rotor amps 41.5 . But its a 11000 btuh unit with 320 cfm, drawback is its like 13 inches tall. The new mach8 cub is 300 cfm . To make more sence of it goto literature & tech docs ,in side of the tech info tab, click on product type - rooftop rv ac ,then product series 9000series , 49000 and 47000 you can still see data and product info on all units they dont make anymore, but any polar cub model will tell you its not avail anymore and refer you to the 47210a876 . look at that about in the middle of all the drop down 47000 series , it says mach8 cub.
If you goggle coleman polar cub you will see PPL , Adventurervnet and all the distributers are seling the 49000 seies until they run out and get in the 47000
They dont make it easy do they
I hope its not me thats making it hard

I believe the reason for the model number change 'may' have to due with the new type (green) refrigerant required, but can't say for sure.

I am not comfortable with the information on the RVP`s website www.rvcomfort.com. Maybe I am just reading it incorrectly, but they say the replacement for 9201D875 would be 47201A876.

When I go to the 47201A876, it says 9200 btu. The Data Sheet link also says 9200 btu, and on High it uses 11.7 amps. The Product Literature Sheet link does not include a 9200 btu unit, it says 13500 and 15000 btu and on High they use 15.3 to 15.9 amps. To me, it makes no since.

I would want more clear information before I made a purchase.

Hay Ripit you might want to look at RVP`s website www.rvcomfort.com , the drop down menu that says literature and tech docs has some tests to do to see if the ac is working properly , the rvp tech ph#is 316-832-4357
If your ac is a 9000 series it should run on a honda , maybee your compressor is worn. If its an old good one and you can get parts from the factory its definatly worth fixing , because you cant get a 9201 anymore
All Polar cubs have soft start kits from the factory,
Ripit you might check the voltage your getting at the ac breaker in the dist panel when the hondas running , lower voltage is going to cause higher amp draw

Reddog I have had 2 model 9201 polar cubs that ran on eco mode at 8000ft elv., all the time and ran great ,one was on a 2004 outfitter apex 9.5
There is a diffrence between saying 9000 series PC`s and 9200btuh PC`s, all PC`s have been 9200 btuh even if some pepole have thought they were 7200 or 8800 or whatever ,the RVP tech told me that in 2005, but the models have changed and even the 9000 series have had diffrent amp draws than the one you have when the model changed from a thru e . All below 9 amp though.
When the freon changed 3-4 years ago the numbers jumped way up , but every one is still quoting around 9 amp draw and when someone askes a"will a polar cub run on a honda "question everyone says yes no problem , but that is not true if you buy one now or in the recent past . I wish it was ,I want one again that pulls only 9 amps
I have not had a newer freon model like a 49201 ,which is still a 9200btuh unit , there are a bunch diff models #`s they made over the last 3-4 years .But when I went to buy one I checked with RVP techs and googled recent results and found that combo is very close to runing or not running together
Right now you can still buy a unit that says polar cub on it , old stock ,but as distributers run out and new mach 8 cubs come in this kind of will it or wont it run discution may be reduced .
I an envious of all of you that have a 4+ year old polar cub , treat them well
You can see all the old and new model unit data sheets on RVP`S website, they started as 9000 series , then went to 4900 series , now 4700 series
