Generator won't run my Coleman Mach 8 Polar Cub

I have the following A/C unit installed on my camper

Coleman Mach 8 Polar Cub (47201A876)
- 9200btu, 11.7 amp on high, 11.2 on low
- low profile


I couldn't find one of the lower draw units so I was hopeful that my little Champion 2000 Inverter generator would run it. No luck, it's not even close really, it goes into overload immediately.

I'm exploring my options now. I carry the generator on a hitch rack on the back that fits under the camper but I don't have much room to fit a larger generator unless I put the camper on a spacer which I don't want to do.

1. Does anyone know if a Hard start capacitor is factory installed in this A/C unit?

2. I think the Honda 2000 will handle a larger startup draw than the Champion, is anyone able to run this mode of A/C with the Honda.

3. I am considering moving up to the 3100 generator, it's about 2" taller but maybe I can take the wheels off ot make it lower.

  • Try putting in a compressor switch. This will allow the blower to come on and then you can manually enable the compressor afterwards. It may also work if you turn the A/C thermostat on warm first so the compressor does not kick on at the same time as the blower. Once the A/C is on, the blower runs constantly and the compressor only cycles based on the thermostat.

    If you have appliances that automatically kick on to AC when there is power (like the water heater or refrigerator) set them to the manual LPG setting to reduce generator load.
