2nd A/C Compressor cutting off

[Longhorn1998]

I have a 32TSBH with two a/cs from the factory. One ducted and the other a stand alone in the front bedroom. When I turn on the stand alone it cools fine and then the compressors cuts off. Is it possible the air from the ducted a/c is interfering with the the knob thermostat on the stand alone. I was hoping I could cool this camper down quick with two units. On my old camper I would run the unit and set it to as cold as possible and the compressor never cut off.

Were you connected to a 50 amp shore power ?

Is it a heat pump? Coleman has issues with the reversing valve sticking and it causes the high pressure switch to shut the compressor off in both heat and cool.

If your stand alone unit isn't ducted and has a removable cover with the supply and return vents in it, be sure to check the seal under that cover that separates the supply and the return. My unit had this problem where the supply air was leaking into the return duct and blowing on the thermostat bulb, This unit had the thermostat and fan control knobs in the roof ac cover end.

I was connected to 50 Amp. It is not a heat pump. I'll check the seal under the cover. I was thinking it might be something like that. It does have the thermostat and temperature control knobs on the cover.
