Domectic Duo Therm Penguin not operating properly?

I just installed a Penguin 11k BTU on my camper to gain some extra inches to be able to get it under the rv spot without hitting it. The problem I am having with the unit is on cool and tempature set to the highest it runs fine. If I turn the tempature knob to less cold it shuts the unit off instead of just the compressor. I have never owned a Dometic Product but I don't think it should do that as my Coleman the fan would stay on and the compressor just cycles. Any input would be appreciated.

    I will have to look at the schematic, as doing some testing for the last couple of days the unit definately shuts off when it reaches temp and then turns back on. I think I also have a bearing going out in the motor so I will need to see how difficult that is to get out of there and replace. It will get a work out this weekend though as we are loaded and headed to Calistoga, CA for our Anniversary! Looking forward to getting away.

    double check the air box wiring, the fan should circulate the air. Page 10 of the operators manual has the wiring diagrams. http://americanrvcompany.com/assets/images/Dometic/PenguinLowProAirCondUsersGuide.pdf

    That is interesting because the manual even speaks of the fan running continously. I will have to do some experimenting to see if it will restart after it does it cycle. If it makes any difference I am not using a thermostat to control not sure if you are.

    I believe yours is operating normally.

    If the thermostat has the option, try running in the auto mode as opposed to specific high, low, or medium settings. See if this makes a difference in the operation.
